Abstract
A determination processing unit determines a disease region in a medical image including an axisymmetric structure. A first determination section of the determination processing unit generates a feature amount map of the medical image from the medical image. A second determination section second inverts the feature amount map with reference to a symmetry axis to generate an inverted feature amount map. A third determination section superimposes the feature amount map and the inverted feature amount map on each other and determines the disease region in the medical image using the feature amount map and the inverted feature amount map superimposed on each other.
Claims7
A medical image processing apparatus, comprising:
- a determination processing unit that determines a disease region in a medical image including an axisymmetric structure,
- wherein the determination processing unit has:
- a first determination section that generates a feature amount map of the medical image from the medical image;
- a second determination section that inverts the feature amount map with reference to a symmetry axis of the feature amount map to generate an inverted feature amount map;
- and
- a third determination section that superimposes the feature amount map and the inverted feature amount map on each other and determines the disease region in the medical image using the feature amount map and the inverted feature amount map superimposed on each other.
A medical image processing method for determining a disease region in a medical image including an axisymmetric structure with a determination processing unit, the method comprising:
- generating a feature amount map of the medical image from the medical image;
- inverting the feature amount map with reference to a symmetry axis of the feature amount map to generate an inverted feature amount map;
- and
- superimposing the feature amount map and the inverted feature amount map on each other and determining the disease region in the medical image using the feature amount map and the inverted feature amount map superimposed on each other.
A non-transitory computer-readable storage medium that stores a medical image processing program causing a computer to execute processing for determining a disease region in a medical image including an axisymmetric structure, the program causing the computer to execute:
- a step of generating a feature amount map of the medical image from the medical image;
- a step of inverting the feature amount map with reference to a symmetry axis of the feature amount map to generate an inverted feature amount map;
- and
- a step of superimposing the feature amount map and the inverted feature amount map on each other and determining the disease region in the medical image using the feature amount map and the inverted feature amount map superimposed on each other.
