    摘要: PROBLEM TO BE SOLVED: To understand a time series variation in signal values of a region of interest in each time phase in detail and effectively based on liver angiographic images obtained at a plurality of time phases in a contrast examination using a contrast agent that reflects a liver blood flow and liver function in an image. SOLUTION: A region-of-interest setting part 32 sets a region of interest in the liver positionally corresponding to each of liver angiopgraphic images between each time phase. A local image generation part 34 generates local sectional images representing an area of interest for each time phase based on each of liver angiographic images in each time phase. A display control part 36 causes the generated local sectional image for each time phase to be displayed in a comparative readable mode. COPYRIGHT: (C)2011,JPO&INPIT

    摘要: Disclosed is an apparatus for analyzing pulse using an array of pressure sensors comprising: an array of pressure sensors that measures the pulse data with a plurality of piezoresistive pressure sensors; a moving part that moves the array of pressure sensors; a controller that controls the moving part, so that the array of pressure sensors can be positioned at the pulse diagnosis site, and analyzes the pulse data measured by the array of pressure sensors; and a display that displays the pulse profile analyzed by the controller. Since both the applied pressure and the pulse pressure can be measured simultaneously using the piezoresistive pressure sensors, various pulse diagnosis techniques can be applied and since pulse length, pulse thickness, etc. can be displayed in four dimensions, softness or roughness of the pulse and other pulse information can be conveyed visually.

    摘要: PROBLEM TO BE SOLVED: To detect a peritoneal cavity region of a subject in a three-dimensional manner with higher accuracy. SOLUTION: The equipment is provided with a bone region extraction section 13 to extract a bone region representing bones of a subject from each of a plurality of axial projection images obtained from a three-dimensional image that shows a region from a location near the upper edge of a liver to a location near a pubic symphysis of a subject, a bone boundary points detection section 16 to detect a plurality of bone boundary points representing boundaries between the bone regions extracted from each of a plurality of axial projection images and regions located at the inner side from the bone regions in the subject, and a peritoneal cavity region extraction section 18 to estimate a curved surface in the three-dimensional image that is almost inscribed in a circle formed by a plurality of bone boundary points detected in each of a plurality of axial projection images for extracting a region surrounded by the curved surface as a three-dimensional peritoneal cavity region.
