Classification: CPC G  A | IPC A  G

Claim 11:
12. A medical image processing system comprising:
a processor configured to:
acquire a medical image obtained by imaging an observation target;
calculate a feature amount of the observation target for each of pixels of an image region of the medical image or for each of divided regions obtained by dividing the image region of the medical image into a specific size;
determine a disease stage of the observation target by using a spatial distribution of the feature amount;
calculate a distribution index value which is an index value of the spatial distribution of the feature amount;
determine the disease stage based on the distribution index value; and
integrate abnormal regions indicating a pixel or a divided region where the feature amount is outside a specific range,

among integrated abnormal regions in which the abnormal regions are integrated, the integrated abnormal region whose area is equal to or larger than a certain value is set as a specific integrated abnormal region, and the integrated abnormal region whose area is less than the certain value is not set as the specific integrated abnormal region,
the distribution index value is an index value related to a spatial distribution of the specific integrated abnormal region,
the distribution index value is a variance of the feature amount, and
a degree of progress of the disease stage increases as the variance of the feature amount increases.
