Abstract
A medical image acquisition unit acquires a medical image obtained by imaging an observation target. A feature amount calculation unit calculates a feature amount of the observation target for each pixel of an image region of the medical image or for each divided region obtained by dividing the image region of the medical image into a specific size. A stage determination unit calculates a distribution index value which is an index value of the spatial distribution of the feature amount of each divided region, and determines the disease stage of the observation target based on the distribution index value.
Claims12
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;
- and
- determine the disease stage based on the distribution index value,
- wherein the distribution index value is a variance of the feature amount,
- the disease stage is an early stage and a progress staged,
- a variation in the spatial distribution of the feature amount in the progress stage is larger than a variation in the spatial distribution of the feature amount in the early stage, and
- a degree of progress of the disease stage increases as the variance of the feature amount increases.

- 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.
