System and method for assessing a patient condition using tertiles derived from capsule endoscope images of the small bowel
A system and method are disclosed, which combine image data of a patient, such as images of the patient's GI tract, with rating mucosal damage. According to some embodiments of the present invention the system and method are able to assess a patient's GI tract condition, to monitor mucosal healing in a patient's GI tract, preferably, the small bowel (SB) mucosa and/or to differentiate between different pathological conditions. The system and method of the invention can provide a value or score arrived at by assigning a grade relating to one or more predetermined parameters.
1. A method, using a computing device, to assess inflammatory changes in a patient's small bowel, the method comprising:
providing to a viewer a series of images of the small bowel captured by a capsule endoscope;
dividing, using the computing device, the series of images into textiles by dividing the series of images to three groups, each group pertaining to one third of the transit time of said capsule endoscope through the small bowel;
receiving, using the computing device, scores including at least a score for at least one image from each textile, the score relating to at least one parameter defining mucosal damage;
combining the scores to obtain a final score; and
displaying the final score.
2. The method according to claim 1 wherein the parameter defining mucosal damage is selected from the group consisting of: denuded mucosa; ulceration; and stenosis and combinations thereof.
3. The method according to claim 1 wherein receiving a score comprises receiving a value for one or more factors selected from the group consisting of number, longitudinal extent, distribution pattern, shape and size.
4. The method according to claim 1 comprising creating a thumbnail of the at least one image.
5. The method according to claim 4 comprising creating a report, said report comprising the thumbnail and the final score.
6. A system for assessing a patient's small bowel mucosa, the system comprising:
a swallowable capsule comprising an imaging device;
a receiver to receive images from the swallowable capsule;
a processor to determine tertiles of the patient's small bowel, wherein each tertile comprises images of the received images captured during one third of the transit time of said swallowable capsule through the small bowel, the processor to display at least one image of each tertile; and
the processor to accept a score for the at least one image from each of the tertiles and to calculate a final score based on the score for the images, wherein said score for the images comprises a value of a parameter defining mucosal condition, wherein the processor is to display the final score.
7. The system according to claim 6 wherein the display comprises a time bar to show a time elapsed for the at least one image of each of the tertiles.
8. The system according to claim 6 wherein the processor is to generate a report, said report comprising a combination of scores including the scores for the images.
9. The system according to claim 8 wherein the report comprises thumbnails of the images.
10. The system according to claim 6 wherein the parameter defining mucosal condition is selected from the group consisting of: denuded mucosa; ulceration; and stenosis.
11. The method according to claim 1 wherein the mucosal damage is a lesion.
12. The method according to claim 1 , wherein the scores include a stenosis score based on the series of images independent of individual tertiles.
