Technical Field

The invention relates to the technical field of intelligent medical image diagnosis, in particular to a child bone age imaging method with lower radiation dose and an imaging device thereof.

Background

At present, a certain proportion of children all over the world are caused to grow and develop to different degrees due to various reasons, and then the children are caused to be short and small after developing. If the children can make bone age examination as early as possible, doctors can find problems as early as possible, and medical intervention is actively carried out under the condition that medical intervention is effective and necessary, so that the children can be helped to normally develop to a great extent, and the normal height is achieved. Unfortunately, medical interventions for these children have a period of validity, and once the period of validity has passed, the effectiveness of the medical intervention is compromised or even completely ineffective. Therefore, timely bone age testing becomes very important for these children.

Generally, the quality of the X-ray image is related to the radiation dose, and the greater the radiation dose, the better the quality of the X-ray image. The quality of an X-ray image can be generally expressed in terms of spatial resolution and signal-to-noise ratio. Spatial resolution refers to the ability of an X-ray image to resolve the details of the image, with higher spatial resolution allowing the physician to see more details in the image. The signal-to-noise ratio represents the ratio of useful signal to unwanted noise in the image. The higher the signal-to-noise ratio, the more useful signals in the representative image, or the lower the unwanted noise in the image, i.e. the better the quality of the image. The X-ray image has high signal-to-noise ratio and more useful signals in the representative image, so that doctors can obtain useful information better to complete film reading and diagnosis. The higher the signal-to-noise ratio of the X-ray image, the lower the noise representing the useless image, the less interference the doctor will disturb when obtaining useful information, and the better the doctor can complete the reading and diagnosis.

Under the same conditions in all other respects, the larger the pixel size of the X-ray detector, the poorer the spatial resolution of the X-ray image, and the higher the signal-to-noise ratio of the X-ray image, and the opposite relationship between the spatial resolution and the signal-to-noise ratio of the X-ray image and the pixel size of the X-ray detector is established, so that the conventional bone age imaging device selects the pixel size of the X-ray detector which is more moderate, and a certain balance is found between the spatial resolution and the signal-to-noise ratio of the X-ray image. The pixel size of the detector using the X-ray is too small, which can cause the required imaging radiation dose to greatly rise and cause radiation damage to the health of the children to be detected; the pixel size of the detector using X-ray is too large, which may cause the spatial resolution of the image to be poor, thereby affecting the diagnosis of bone age of children.

Detailed Description

For a further understanding of the present invention, reference is made to the following detailed description taken in conjunction with the accompanying drawings 1-5 and examples.

Example one

With reference to fig. 1, the method for bone age imaging of children with lower radiation dose of the embodiment includes the following steps: s1: collecting an X-ray image of the age of a hand bone; s2: the spatial resolution of the X-ray image is improved by using an ultrahigh resolution technology; s3: outputting an X-ray image with improved spatial resolution;

according to the child bone age imaging method with the lower radiation dose, pixel size combination is not performed, and according to the requirements of practical application, the operation of improving the spatial resolution is performed in the vertical and horizontal directions by using an image ultrahigh resolution technology, so that doctors can see more image details. Better quality (higher spatial resolution, same image signal to noise ratio) X-ray images can be obtained using a predetermined radiation dose. This mode is similar to the mode of operation where handset vendors use virtual pixels to increase spatial resolution. This does not reduce the radiation dose, but can improve the spatial resolution of the image pattern for certain applications, for example, which is beneficial for examining small bone fractures and ultra-fine bone texture imaging.

Ultra-high Resolution (Super-Resolution) techniques, also known as "Super-Resolution", increase the spatial Resolution of the detector. In recent years, image super-high resolution technology has been developed very rapidly. From the conventional linear image interpolation which is commonly used for improving the spatial resolution of the image to the bicubic interpolation, the image ultrahigh resolution technology based on artificial intelligence is developed for the years, and the image ultrahigh resolution technology greatly improves the spatial resolution of the image. By using so-called ultra-high resolution techniques, one can restore the original low spatial resolution image to an image that is nearly identical to the high resolution image. At present, the development of image ultrahigh resolution technology is a coming and going day by day, and more than one hundred image ultrahigh resolution technologies based on artificial intelligence can be used.

In addition, while the image ultrahigh resolution technology has been rapidly developed, in recent years, the image denoising technology based on artificial intelligence has been rapidly developed. Generally, the image super-resolution technology and the image noise reduction technology can be used separately to respectively improve the spatial resolution of the image and the signal-to-noise ratio of the image. However, some new artificial intelligence image quality improvement techniques have appeared. The image super-resolution technology and the image noise reduction technology can be fused together, and the spatial resolution of the image and the signal-to-noise ratio of the image can be improved simultaneously only by processing the image once. The image quality improvement technology in this patent includes the case of using the image ultrahigh resolution technology and the image noise reduction technology separately, and also includes such combined technology that can simultaneously improve the spatial resolution of the image and the signal-to-noise ratio of the image.

Because the patent only needs to use the image ultrahigh resolution technology and the image noise reduction technology, and does not need to develop new image ultrahigh resolution or image noise reduction technology or algorithm, the working principles of the image ultrahigh resolution technology and the image noise reduction technology are not repeated herein.

The child bone age imaging method with lower radiation dose can reduce the radiation dose required by image acquisition under the condition of jointly using an ultrahigh resolution technology when a doctor independently makes an artificial bone age interpretation.

Example two

With reference to fig. 2, the method for bone age imaging of children with lower radiation dose of the embodiment includes the following steps: s01: setting a pixel size merging parameter of an X-ray detector; s02: setting the radiation dose of X-ray of an X-ray generator; s1: collecting an X-ray image of the age of a hand bone; s2: according to the pixel size combination parameters, the spatial resolution of the X-ray image is improved by using an ultrahigh resolution technology; s3: outputting an X-ray image with improved spatial resolution; the X-ray detector collects an X-ray image according to the set pixel size combination parameter; the X-ray generator emits X-rays according to the set radiation dose of the X-rays.

In the present embodiment, although the pixel size of any X-ray detector is a fixed physical size and cannot be changed, one can flexibly increase the equivalent pixel size by combining pixels. For example, one can combine a total of 4 physical pixels, up, down, left, right, left, and right, in up, down, left, and right directions by a factor of 2 × 2 into one pixel. Thus, an equivalent pixel 4 times as large can be obtained, and the light sensing capability of the equivalent pixel is greatly increased. In general, a 4X equivalent pixel provides approximately 4X sensitivity, which is equivalent to an X-ray film that can be obtained with a radiation dose that is 4X smaller to achieve a similar signal-to-noise ratio. One can even use a pixel combination of 4 × 4 times of total 16 physical pixels of upper, lower, left and right in the upper, lower, left and right directions to form an equivalent pixel 16 times larger, so as to obtain an X-ray film with similar signal-to-noise ratio with a radiation dose 16 times smaller. Of course, the only problem with this is that the spatial resolution of the detector is reduced.

The method for children bone age imaging with lower radiation dose can restore the lower spatial resolution of the image caused by pixel size combination to the spatial resolution similar to the spatial resolution of the image which is obtained when the pixel size combination is not used by using the image ultrahigh resolution technology. In fact, the pixel size combining can be done with the same or different pixel size combining in both the vertical and horizontal directions. If the pixel size combination is carried out in the vertical direction and the horizontal direction in the same two-in-one mode, namely the pixel size combination of the upper-lower two-in-one mode and the left-right two-in-one mode, the same operation of improving the spatial resolution by one time is carried out in the vertical direction and the horizontal direction by the image ultrahigh resolution technology. In practical applications, some applications may have different requirements on spatial resolution in the vertical and horizontal directions, and the image super-resolution technique is used to operate different pixel size combinations in the vertical and horizontal directions. For example, if the pixel size combination is only the left-right two-in-one pixel size combination in the horizontal direction, but no pixel size combination is performed in the vertical direction, only the image super-resolution technology needs to be used to perform the operation of increasing the spatial resolution by one time in the horizontal direction, and no operation of increasing the spatial resolution in the vertical direction needs to be performed on the image. Similarly, if the pixel size combination is only the left-right two-in-one pixel size combination in the vertical direction, but no pixel size combination is performed in the horizontal direction, the corresponding operation of increasing the spatial resolution by one time in the vertical direction by using the image ultrahigh resolution technology is only needed, and the operation of increasing the spatial resolution in the horizontal direction is not needed. Generally, if the pixel size combination is performed by N × M times in the vertical and horizontal directions, respectively, then the super high resolution technique is used to perform operations of increasing the spatial resolution by N and M times in the vertical and horizontal directions, where M and N may not be equal to each other, and M and N are positive integers greater than or equal to one. The child bone age imaging method with lower radiation dose can independently select the size of pixel size combination in the vertical direction and the horizontal direction, and independently use the image ultrahigh resolution technology to carry out the operation of improving the spatial resolution in the vertical direction and the horizontal direction.

According to the child bone age imaging method with the lower radiation dose, the equivalent pixel size is greatly improved by utilizing pixel size combination, and the signal to noise ratio of an image obtained by a detector is greatly improved. If the pixel size binning is performed with N x M times the pixel size binning in the vertical and horizontal direction, respectively, one can use a smaller radiation dose than without binning, i.e. a dose (N x M) times smaller than the original radiation dose, to obtain a similar signal to noise ratio of the image as without pixel size binning. If the pixel sizes are combined into four-in-one (N-2, M-2, N × M-4), one can theoretically use one-fourth of the original radiation dose to obtain a similar signal-to-noise ratio of the image, and the main purpose of this mode is to reduce the radiation dose and better protect the subject.

The present method of bone age imaging in children with lower radiation doses allows one to choose to reduce the radiation dose appropriately if the pixel size binning is performed N x M times the pixel size binning in the vertical and horizontal direction, respectively, instead of choosing a dose that is (N x M) times smaller than the original radiation dose. If the pixel sizes are combined into four (N2, M2) for top, bottom, left and right, one could theoretically use one quarter of the original radiation dose to obtain a similar signal-to-noise ratio of the image, but one could choose to use one half of the original radiation dose to obtain a higher signal-to-noise ratio than the original image. Then, the image ultrahigh resolution technology is used for improving the spatial resolution in the vertical and horizontal directions, so that people can obtain better quality (similar spatial resolution and higher image signal to noise ratio) X-ray images under the condition of saving half of radiation dose.

The children bone age imaging method with lower radiation dose can reduce the radiation dose required by the collected image in multiples under the condition of obtaining the signal to noise ratio of similar images by flexibly using the same or different pixel sizes in two directions for combination; then the spatial resolution of the image is improved by the application of the ultra-high resolution technology which is the same or different in two directions; the aim of greatly reducing the radiation dose required during imaging is fulfilled, and the physical health of the detected children is protected; by flexibly using the combination of the same or different pixel sizes in the two directions, the radiation dose used during image acquisition and the application of the same or different ultrahigh resolution technology in the two directions, flexible and changeable selection can be made on the imaging radiation dose and the image quality of the image according to the requirements of practical application, and the dual purposes of finally reducing the radiation dose required during imaging and improving the image quality are achieved.

EXAMPLE III

With reference to fig. 3, the method for bone age imaging of children with lower radiation dose of the embodiment includes the following steps: s1: setting a pixel size merging parameter of an X-ray detector; s2: setting the radiation dose of X-ray of an X-ray generator; s3: collecting an X-ray image of the age of a hand bone; s4: carrying out data processing suitable for artificial intelligence interpretation on the X-ray image; s5: outputting data suitable for artificial intelligence interpretation; s6: the data is used for bone age interpretation by artificial intelligence; s7: and outputting an artificial intelligent bone age diagnosis result.

The artificial intelligence does not directly use the image data that people are accustomed to seeing when doing automatic bone age judgement. For example, the artificial intelligence model can not be interpreted by directly using image data of different sizes, and generally, images of different sizes are converted into image data of the same size through preprocessing such as image scaling; for another example, the artificial intelligence generally cannot directly use the image data of the integer, and generally the artificial intelligence model can be interpreted after the image data of the integer is converted into floating point data through normalization and other processing; for another example, when the bone age is judged, the artificial intelligence generally does not need the image with high spatial resolution, only needs the image obtained after the pixel size combination, basically does not need to use the ultrahigh resolution technology to improve the resolution of the X-ray image, and can achieve the purpose of reducing the radiation dose by utilizing the pixel size combination.

According to the child bone age imaging method with the lower radiation dose, the same or different pixel sizes in two directions are flexibly used for combination, and the radiation dose required for acquiring images can be greatly reduced without using an ultrahigh resolution technology when artificial intelligence is independently used for bone age judgment, so that the body health of a detected child is effectively protected.

Example four

With reference to fig. 4, the method for bone age imaging of children with lower radiation dose of the embodiment includes the following steps: s1: setting a pixel size merging parameter of an X-ray detector; s2: setting the radiation dose of X-ray of an X-ray generator; s3: collecting an X-ray image of the age of a hand bone; s4: carrying out data processing suitable for artificial intelligence interpretation on the X-ray image; s5: outputting data suitable for artificial intelligence interpretation; s6: the data is used for bone age interpretation by artificial intelligence; s7: outputting an artificial intelligent bone age diagnosis result; s8: according to the pixel size combination parameters, the spatial resolution of the X-ray image in the S3 is improved by using an ultrahigh resolution technology; s9: outputting an X-ray image with improved spatial resolution; s10: and outputting an artificial intelligent auxiliary diagnosis result by combining the X-ray image and the bone age interpretation result.

According to the children bone age imaging method with the lower radiation dose, the same or different pixel sizes in two directions are combined through flexible use, when an artificial intelligence assistant doctor is used for bone age interpretation, the radiation dose required for image acquisition can be reduced under the condition of jointly using an ultrahigh resolution technology, the bone age interpretation efficiency and accuracy are improved, and error diagnosis caused by artificial factors is reduced. In fact, in the application of actual artificial intelligence interpretation in many hospitals, doctors generally have a prejudice on the artificial intelligence interpretation result, and large errors in artificial intelligence interpretation are prevented. Meanwhile, doctors often do not have sufficient confidence in their interpretation, and need to refer to and even use the results of artificial intelligent interpretation as the final interpretation results. This process is referred to as artificial intelligence assisted diagnosis. The artificial intelligence auxiliary diagnosis can greatly reduce the working strength of doctors, accelerate the diagnosis speed, improve the diagnosis efficiency, improve the diagnosis accuracy and greatly reduce the possibility of error diagnosis of the doctors in a fatigue or distraction state.
