Abstract
In one embodiment, a medical image processing apparatus includes memory circuitry configured to store a program; and processing circuitry configured, by executing the program, to set a region of interest in a medical image, set an analysis region in the region of interest by reducing the region of interest, and calculate feature amount in the analysis region.
Claims13
A medical insane analysis apparatus, comprising:
- memory circuitry configured to store a program;
- and
- processing circuitry configured to, by executing the program,
- set a region of interest in a medical image,
- set an analysis region in the region of interest by reducing the region of interest,
- set a predetermined margin between the region of interest and the analysis region,
- apply local texture anal analysis to plural spots set in the analysis region defined by the predetermined margin,
- determine whether the predetermined margin is appropriate or not, based on differences in index values obtained by the texture analysis applied to the plural spots,
- reduce the analysis region when the predetermined margin is not determined to be appropriate, while maintaining the analysis region when the predetermined margin is determined to be appropriate, and
- calculate a feature amount in the analysis region that has been reduced or maintained.
