Abstract

A medical scan assisted review system is operable to receive, via a network, a medical scan for review. Abnormality data is generated by identifying a plurality of abnormalities in the medical scan by utilizing a computer vision model that is trained on a plurality of training medical scans. The abnormality data includes location data and classification data for each of the plurality of abnormalities. Text describing each of the plurality of abnormalities is generated based on the abnormality data. The abnormality data and the text is transmitted to a client device. A display device associated with the client device displays the abnormality data in conjunction with the medical scan via an interactive interface, and the display device further displays the text via the interactive interface.

First claim

What is claimed is:

1. A medical scan assisted review system, comprising:
a processing system that includes a processor; and
a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations comprising:
receiving, via a network, a first medical scan for review;
generating abnormality data by utilizing a computer vision model to automatically identify a plurality of abnormalities in the first medical scan, wherein the computer vision model is trained on a plurality of training medical scans, wherein each of the plurality of training medical scans include imaging data corresponding to a medical scan taken of a human body, wherein the abnormality data includes location data and classification data for each of the plurality of abnormalities, and wherein the location data and classification data for each of the plurality of abnormalities is automatically generated by utilizing the computer vision model;
generating display parameter data that indicates an automatically selected image slice of a plurality of image slices of the first medical scan for each of the plurality of abnormalities based on the automatically selected image slice being determined to include the each of the plurality of abnormalities;
transmitting the abnormality data and the display parameter data to a client device associated with a user of the medical scan assisted review system, wherein a display device associated with the client device facilitates review of each of the plurality of abnormalities by displaying the location data and the classification data for each of the plurality of abnormalities in conjunction with the first medical scan via an interactive interface;
wherein the client device utilizes the display parameter data to facilitate review of one of the plurality of abnormalities in the first medical scan by automatically displaying, via the display device, an automatically selected one of the plurality of image slices of the first medical scan corresponding to the one of the plurality of abnormalities in the display parameter data.

2. The medical scan assisted review system of claim 1 , wherein the display device, based on user input via the interactive interface indicating a selection to review a different one of the plurality of abnormalities identified in the abnormality data, utilizes the display parameter data to change from displaying, via the display device, the one of the plurality of abnormalities to displaying the different one of the plurality of abnormalities by automatically jumping to a different automatically selected one of the plurality of image slices that corresponds to the different one of the plurality of abnormalities in the display parameter data.

3. The medical scan assisted review system of claim 1 , wherein generating the display parameter data includes automatically selecting a density window for each of the plurality of abnormalities, wherein the client device utilizes the display parameter data to facilitate review of one of the plurality of abnormalities in the first medical scan via the interactive interface by automatically displaying, via the display device, the first medical scan in accordance with a first density window that corresponds to the one of the plurality of abnormalities in the display parameter data, and wherein the display device, based on to user input via the interactive interface indicating a selection to review a different one of the plurality of abnormalities identified in the abnormality data, automatically changes from displaying the first medical scan in accordance with a first density window to displaying the first medical scan in accordance with a different density window that corresponds to the different one of the plurality of abnormalities in the display parameter data.

4. The medical scan assisted review system of claim 1 , wherein the automatically selected one of the plurality of image slices of the first medical scan corresponds to an automatically selected cross-sectional image slice of one of: a magnetic resonance imaging (MRI) scan or a computerized tomography (CT) scan.

5. The medical scan assisted review system of claim 1 , wherein the display device displays the first medical scan in a first view of the interactive interface, and wherein the operations further comprise:
selecting a set of similar medical scans from the plurality of training medical scans by applying a similarity function to determine that a known abnormality included in each of the set of similar medical scan compares favorably to a corresponding one of the plurality of abnormalities; and
transmitting the set of similar medical scans to the client device;
wherein one of the set of similar medical scans corresponding to the one of the plurality of abnormalities is automatically displayed in a second view of the interactive interface that is adjacent to the first view in response to a second prompt via the interactive interface.

6. The medical scan assisted review system of claim 5 , wherein the first medical scan includes a first plurality of image slices, wherein the one of the set of similar medical scans includes a second plurality of image slices, and wherein the second view of the interactive interface automatically jumps to a one of the second plurality of image slices in response to the second prompt that corresponds to a currently displayed one of the first plurality of image slices of the first view.

7. The medical scan assisted review system of claim 6 , wherein the one of the second plurality of image slices is selected based on determining that the one of the second plurality of image slices compares favorably to a cross sectional anatomical region of the currently displayed one of the first plurality of image slices of the first view.

8. The medical scan assisted review system of claim 6 , wherein the one of the second plurality of image slices is selected based on determining that the one of the second plurality of image slices includes a view of the known abnormality that compares favorably to the one of the plurality of abnormalities.

9. The medical scan assisted review system of claim 6 , wherein the first view scrolls to a new one of the first plurality of image slices in response to a third prompt to scroll to the new one of the first plurality of image slices via the interactive interface, and wherein the second view simultaneously scrolls to a corresponding new one of the second plurality of image slices in response to the third prompt.

10. The medical scan assisted review system of claim 5 , wherein each of the set of similar medical scans is associated with a patient record, and wherein each of the set of similar medical scans are selected based on the associated patient record comparing favorably to a longitudinal quality threshold.

11. The medical scan assisted review system of claim 10 , wherein the operations further comprise:
transmitting, via the network, a more recent medical scan indicated in the patient record associated with the one of the set of similar medical scans corresponding to the one of the plurality of abnormalities, wherein the more recent medical scan is displayed by display device in response to a third prompt via the interactive interface.

12. The medical scan assisted review system of claim 1 , wherein the operations further comprise:
receiving, via the network, new abnormality data in response to a second prompt via the interactive interface, wherein a location of the new abnormality data is based on a region identified in the medical scan via the interactive interface; and
generating updated abnormality data based on the new abnormality data.
