Technical Field

The present invention relates to a bone marrow reading support device, and more particularly, to a bone marrow reading support device based on image analysis, which provides an image for bone marrow reading and provides a discrimination coefficient by classifying bone marrow cells into different categories by category, so that bone marrow reading can be efficiently and easily performed.

Background

Bone marrow examination is one of diagnostic tests performed by collecting bone marrow as a hematopoietic organ. This bone marrow examination is used not only for the diagnosis of various blood diseases and follow-up examination after treatment, but also for the judgment of whether various cancers have metastasized to the bone marrow and are affected by granulomatous diseases such as tuberculosis.

A blood diagnosis specialist observes a stained bone marrow smear and a bone marrow biopsy under a microscope for the purpose of reading bone marrow, and performs diagnosis by synthesizing differentiation coefficients of bone marrow cells. Furthermore, if necessary, comprehensive diagnosis should be performed by observing slides of multiple kinds of specifically stained smears or immunostained biopsy sections. Such a work requires extensive experience and knowledge, and the observing doctor must spend a lot of time because of the need to observe a plurality of portions of the slide glass at a high magnification, thereby often causing severe eye fatigue.

In addition, in the case of difficult reading, the opinion of other experts is required to be solicited, so that the slide of bone marrow needs to be packed and sent by mail or express delivery, and after it has to be observed again using a microscope at the place where it is received, the result is sent by wire or paper, and then the slide is returned. Due to such inconvenience and time consumption, there arises a problem that information required for the day of examination cannot be transmitted to a clinician who makes a patient visit.

In general, one must take a photomicrograph in order to use a bone marrow image, which is poor in quality and is taken only of cells in a part desired by an observer, and thus cannot be used for diagnosis. Furthermore, the bone marrow reading training method has no other method than one-to-one training with many limitations, which requires microscopic observation. Even with mapping, practical use in training is limited due to the fact that there are only a few pictures of typical cell types. The same causes arise in the absence of quality control methods for determining whether a bone marrow examination reading was performed correctly.

Bone marrow reading supporting device based on image analysis

Fig. 1 is a diagram illustrating the configuration of a bone marrow reading support device based on image analysis according to an embodiment of the present invention, fig. 2 is a flowchart illustrating a time-series processing flow according to an embodiment of the present invention, fig. 3 is a flowchart illustrating a reading process of a discrimination coefficient section 20 employed in an embodiment of the present invention, fig. 4 is a diagram illustrating an example of an image obtained by an image obtaining section 10 employed in an embodiment of the present invention, fig. 5 is a photograph illustrating an enlarged image of an image around a macro-particle in fig. 4, and fig. 6 is a photograph illustrating an example of a result provided by a result providing section 30 employed in an embodiment of the present invention.

As shown in fig. 1 and 2, a bone marrow reading support device based on image analysis according to an embodiment of the present invention includes: an image acquisition unit 10, a discrimination coefficient unit 20, and a result providing unit 30.

The image obtaining part 10 obtains (S1) an image of the bone marrow cells as shown in fig. 4 and 5 using an imaging device such as CT, so that the doctor can photograph and provide all images for bone marrow reading.

As shown in fig. 4 and 5, the identification coefficient section 20 generates (S2) the acquired bone marrow image as a necessary image through image processing and software control, and classifies (S3) it into any one of a plurality of categories included in the identification coefficient through a preset algorithm.

The necessary image is, for example, a large particle having a size larger than the size of other particles around in the bone marrow image screen, and the present embodiment captures and provides the necessary image of as many large particles as the specified number.

This embodiment generates cells present in the region of interest before and after the macro particle as necessary images together with the macro particle, and the generated necessary images can be provided in a specified number. That is, after a sufficient size is specified to the front of the particle and the image is taken in order to determine the megakaryocytes, as many as the specified number are provided, and the megakaryocytes are detected by software and an image of high magnification is taken and provided.

The bone marrow cell discrimination coefficient is determined by a cell classification algorithm using a high-magnification cell image obtained from a site where cells are well smeared, and the result providing unit 30 provides the discrimination coefficient together with a necessary image (S4).

For example, the result provider 30 may be configured to: when the slide glass on which the bone marrow to be read is placed is a smear of special staining other than basic bone marrow staining, a specified number of particle images, a region-of-interest image, and a high-magnification cell image can be provided. In addition, the user can set the number of all images to be provided. Bone marrow tissue sections can provide complete images of all conventional, immunostaining, and special staining, and the demander can zoom in to the desired size by clicking.

Here, the discrimination coefficient may be determined in various ways, but is preferably determined in consideration of a characteristic factor of the bone marrow. For example, in the bone marrow cells, the discrimination coefficient is preferably determined based on the site that is most likely to display the bone marrow examination result because of the least contamination of peripheral blood, among the adjacent sites before and after the macroparticle having relatively large particles.

Accordingly, as shown in fig. 3, the discrimination coefficient unit 20 employed in the present embodiment classifies bone marrow images into different categories based on discrimination coefficients determined based on the size and shape of macroparticles having a size larger than other surrounding particles in the bone marrow image screen and the size and shape of megakaryocytes (megakaryocytes) present in the regions of interest before and after the macroparticles.

As shown in fig. 6, the result providing section 30 functions to provide the necessary image together with the result of the discrimination by the discrimination coefficient section 20.

The bone marrow read support device based on image analysis according to an embodiment of the present invention having such a configuration is configured to be able to classify all bone marrow images secured by an imaging device such as CT into any one of different categories classified according to an identification factor and provide them, thereby enabling bone marrow reading without microscopic observation, thereby having an advantage that labor and time can be saved, and to be able to read bone marrow images by an identification factor reflected by an algorithm for bone marrow cell identification, thereby having an advantage that consultation with other experts or remote reading at a central reading center or the like can be possible, and also having an advantage that complete image composition training data can be provided to a bone marrow reader doctor.

The present embodiment further includes a database part 40 storing a plurality of bone marrow images classified by category according to a previously determined identification coefficient, and the result providing part 30 is configured to provide the data analyzed by the identification coefficient part 20 together with the data stored in the database part 40, so that the user can compare and analyze the bone marrow image actually read and the bone marrow image databased, thereby having an effect of enabling more accurate bone marrow reading.

Although various embodiments of the present invention have been described above, the present embodiment and the accompanying drawings are only illustrative of some of the technical ideas included in the present invention. It is apparent that modifications and specific embodiments, which can be easily made by those skilled in the art, within the scope of the technical idea included in the specification and the drawings of the present invention are included in the scope of the present invention.
