To provide an image processing device and a spinal canal evaluation method that can evaluate the spinal canal stenosis in an identified cross-sectional position, the image processing deviceextracts a vertebral region from a series of tomographic images in which at least a part of the spine was scanned and calculates a length in the anteroposterior direction of an object for each cross section in each vertebral region. Also, a cross section including a spinous process is identified based on the calculated length in the anteroposterior direction of an object in each vertebral region, the spinal canal stenosis is evaluated by setting the identified cross-sectional position to be analyzed, and then the evaluation results are displayed. Hence, stenosis evaluation can be performed for various shapes of the spinal canal region in which a closed space hardly appears on an image due to many gaps.

Image processing device and spinal canal evaluation method

Provided is a medical image processing device including: medical image information acquisition unit which acquires medical image information indicating a tomographic image of an object to be examined; evaluation region extraction unit which extracts an evaluation region for each of the tissues contained in the acquired medical image information according to a pixel value, a concentration value, or a luminance value for each of the tissues; and evaluation region display unit which displays the evaluation region on a display device.

Medical imaging processing device, medical image processing method, and program

A medical image diagnosing support apparatus comprises: a first extraction means which extracts a body region of a subject from a tomographic image of the subject acquired by a medical tomographic apparatus; a second extraction means which extracts a non-adipose region from the body region; a third extraction means which extracts a total body adipose region from the body region; a separation means which separates the total body adipose region into a visceral adipose region and a subcutaneous adipose region based on positional information of the non-adipose region; and a display control means which controls of displaying the tomographic image on an image display device with clear indication of the visceral adipose region and the subcutaneous adipose region.

Apparatus and method of supporting diagnostic imaging for medical use

A medical image diagnosing support method is provided that includes a site region extracting step for obtaining a tomographic image which is picked up by a medical diagnostic imaging apparatus and extracting a predetermined site region from the obtained tomographic image, a first region extracting step for extracting a first lesion candidate region from the site region based on pixel values of the site region extracted in the predetermined site region extracting step, a second region extracting step for extracting a second lesion candidate region from the site region based on a distribution of the pixel values of the site region extracted in the predetermined site region extracting step, and a region correcting step for correcting the first lesion candidate region extracted in the first region extracting step by using the second lesion candidate region extracted in the second region extracting step.
