Medical image processing device and medical image processing method
First Claim
Patent Images
1. A medical image processing device, comprising:
- a three-dimensional surface shape generation section that generates a three-dimensional surface shape reflecting a surface shape of an observation target in a medical image based on a two-dimensional image obtained from at least one color signal in the medical image including a plurality of color signals;
a lesion candidate region detecting section that detects a lesion candidate region which comprises a region with an elevation change or a region with a depression change, utilizing information of the three-dimensional surface shape that is generated by the three-dimensional surface shape generation section;
an incidental region detecting section that detects an incidental region that arises because of incidental attributes accompanying a lesion from the medical image; and
a detection standard changing section that changes a detection standard when detecting a lesion from the lesion candidate region in accordance with a detection result of the incidental region;
wherein the detection standard changing section uses, as the detection standard, a first detection standard when the incidental region is not detected, and a second detection standard which is more relaxed than the first detection standard when the incidental region is detected.

Abstract
An image processing device includes; a lesion candidate region detecting section that detects a lesion candidate region based on at least one color signal in a medical image including a plurality of color signals; an incidental region detecting section that detects an incidental region that arises because of incidental attributes accompanying a lesion from the medical image; and a detection standard changing section that changes a detection standard when detecting a lesion from the lesion candidate region in accordance with a detection result of the incidental region.

8. A medical image processing method, comprising:
-
a three-dimensional surface shape generation step that generates a three-dimensional surface shape reflecting a surface shape of an observation target in a medical image based on a two-dimensional image obtained from at least one color signal in the medical image including a plurality of color signals; a lesion candidate region detection step that detects a lesion candidate region which comprises a region with an elevation change or a region with a depression change, utilizing information of the three-dimensional surface shape that is generated by the three-dimensional surface shape generation step; an incidental region detection step that detects existence or non-existence of an incidental region that arises because of incidental attributes accompanying a lesion from the medical image; and a detection standard changing step that changes a detection standard when detecting a lesion from the lesion candidate region according to a detection result regarding existence or non-existence of the incidental region; wherein the detection standard changing step uses, as the detection standard, a first detection standard when the incidental region is not detected, and a second detection standard which is more relaxed than the first detection standard when the incidental region is detected. - View Dependent Claims (9, 10, 11, 12)
