Image processing device, living body observation device and image processing method

Abstract

Allows the surgeon to grasp areas where fat detection cannot be detected correctly due to the influence of blood or other interference, reducing the risk of nerve damage. An image processing unit is provided, comprising: a fat area setting unit (32) that detects fat area information indicating a fat area where fat exists in a biopsy image; a fat area reliability calculation unit (37) that calculates the reliability of the fat area information detected by the area setting unit (32); and the display mode setting unit which displays the fat area whose calculation reliability calculated by the fat area reliability calculation unit (37) is lower than the reference reliability as a reference. The fat region indicated by the region information is processed into a display format that can be distinguished from the surrounding region.

Description

technical field [0001] The present invention relates to an image processing device, a living body observation device and an image processing method. Background technique [0002] Conventionally, narrow-band light observation (NBI) for emphasizing and displaying capillaries on the mucosal surface and the like by irradiating illumination light of a narrowed-band wavelength that is easily absorbed by hemoglobin contained in blood is known (see, for example, Patent Document 1). [0003] This narrow-band light observation is expected as an alternative observation method for pigment dispersion widely performed for detailed diagnosis of the esophagus region or observation of pockmarked images (glandular structure) of the large intestine. Based on the reduction of examination time and unnecessary biopsies, It can be expected to contribute to the improvement of inspection efficiency. [0004] However, narrow-band light observation is capable of emphasizing blood vessels, but it is d...

Problems solved by technology

[0004] However, although narrow-band light observation can emphasize blood vessels, it is difficult to emphasize nerves

[0005] For example, when nerves are preserved in total rectal resection or total prostatectomy, it is necessary to expose the target organ in order not to injure the nerves distributed so as to surround the target organ when resecting the target organ. However, thin nerves with a diameter of 50 to 300 μm are white or transparent, so it is difficult to observe even with magnified observation using a laparoscope

Therefore, doctors have to rely on experience or feeling to perform surgery, and there is a disadvantage that the possibility of nerve damage is high.
