Title:
MEDICAL IMAGE PROCESSING DEVICE, MEDICAL IMAGE PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2017/159335
Kind Code:
A1
Abstract:
The present invention pertains to a medical image processing device, a medical image processing method, and a program, which allow accurate detection of a surgical instrument. The present invention is provided with an imaging unit for taking an image of an object having a luminescent marker arranged thereon, and a processing unit for processing the image taken by the imaging unit. The processing unit extracts a color of light emitted by the luminescent marker from the image, and detects a region within the image where the extracted color is distributed as a region where the object is located. Moreover, the processing unit calculates the chromaticity for each pixel within the image, extracts a pixel having the chromaticity corresponding to the color of light emitted by the luminescent marker, and detects the extracted pixel as a region where the object is present. The present invention can be applied to, for example, an endoscope system, a surgical operation system, a microscopic surgical operation system, and the like.
