In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

One of the core ideas of the embodiment of the invention is to provide an X-ray image acquisition method, which comprises the following steps: linking the flat panel detector with the visual field of the beam splitter, and acquiring original image data; and processing the original image data to obtain target image data. After the size of the beam-forming device is set according to the size of the current projection body position, the working visual field of the flat panel detector is adjusted according to the irradiation visual field of the X-ray by the flat panel detector, and the working visual field of the flat panel detector is consistent with the projection visual field of the X-ray. The data acquired by the flat panel detector will not include data for areas not exposed to X-rays. Therefore, the interference of invalid data to valid data is avoided, the image quality is improved, the data acquisition amount is reduced, and the image processing time is greatly shortened. Because the flat panel detector does not receive useless information, images do not need to be cut, and therefore working efficiency is improved.

Referring to fig. 1, a flow chart of steps of an embodiment of a method of X-ray image acquisition of the present invention is shown, which may specifically include the following steps:

s1, linking the flat panel detector with the field of view of the beam splitter, and collecting original image data;

in this embodiment, a method of X-ray image acquisition is suitable for a control system with a beam splitter capable of changing the X-ray field of view in real time by program control instructions and a flat panel detector capable of changing the working field of view in real time by program control instructions. The working view field of the beam splitter is collected and sent to the flat panel detector in real time in the embodiment, so that the real-time linkage of the beam splitter and the flat panel detector is realized, effective original image data are directly collected, and the original data do not include data without an X-ray projection area. Therefore, the interference of invalid data to valid data is avoided, the image quality is improved, the data acquisition amount is reduced, and the image processing time is greatly shortened. Because the flat panel detector does not receive useless information, images do not need to be cut, and therefore working efficiency is improved.

And S2, processing the original image data to obtain target image data. The effective target image data is processed, and the image processing algorithm can complete processing more easily and rapidly due to the reduction of the image data amount and no interference of invalid information, and the image quality is improved.

In this embodiment, the step of linking the flat panel detector with the field of view of the beam splitter and collecting the original image data includes:

s101, collecting first opening data of a beam splitter;

s102, adjusting the opening of the flat panel detector by adopting the first opening data, and acquiring original image data.

By the method, the field of view of the flat panel detector is linked with the field of view of the beam splitter, the first opening data is linked with the size of the opening of the flat panel detector, and the acquired original image data does not contain invalid information. The working range of the flat panel detector is reduced, and the interference of the acquired data volume and useless information is reduced; and convenience is brought to image processing.

In this embodiment, after the step of processing the original image data to obtain the target image data, the method includes:

s3, storing the target image data in a database.

In this embodiment, since the processed target image data does not include invalid information, the target image data can be directly archived without cutting during the imaging process. The working efficiency is improved.

The opening size of the beam splitter can be automatically adjusted according to the registered body position information of a patient, and the irradiation field of X-rays and the collection range of an image receiving surface are controlled. The opening size of the beam splitter can be adjusted through the control button, and when the opening size of the beam splitter is changed, the visual field of the flat panel detector can be kept consistent with the opening size of the beam splitter. The invention can greatly reduce the radiation dose of the patient, reduce the workload of the doctor for cutting the image and improve the image processing speed and the image quality.
