摘要： A diagnostic assistance device is a diagnostic assistance device configured to generate three-dimensional data of a biological tissue based on tomographic data of the biological tissue, and display the generated three-dimensional data as a three-dimensional image on a display. The diagnostic assistance device includes a control unit configured to adjust a color tone of each voxel of the three-dimensional image according to a distance from a reference point, a reference line, or a reference plane in a three-dimensional space to each point of the three-dimensional data.

摘要： An information processing method for assisting a user to be capable of smoothly ascertaining necessary information. An information processing method causes a computer to execute processing for acquiring classification data in which pixels constituting biomedical image data indicating an internal structure of a living body are classified into a plurality of regions including a living tissue region in which a luminal region exists, the luminal region, and an extraluminal region outside the living tissue region, and generating region contour data, in which a portion where a thickness from an inner surface of the living tissue region facing the luminal region exceeds a predetermined threshold is removed from the living tissue region, based on the classification data.

摘要： An image processing device is an image processing device configured to cause a display to display, as a three-dimensional image, three-dimensional data representing a biological tissue having a longitudinal lumen. The image processing device includes: a control unit configured to calculate centroid positions of a plurality of cross sections in a lateral direction of the lumen of the biological tissue by using the three-dimensional data, set a pair of planes intersecting at a single line passing through the calculated centroid positions as cutting planes, and form, in the three-dimensional data, an opening exposing the lumen of the biological tissue from a region interposed between the cutting planes in the three-dimensional image.

摘要： An image processing device includes a drive unit connected with an ultrasound element or an image sensor element, and an image processing unit that sequentially generates two-dimensional images of an organ, a blood vessel, or a medical instrument, based on information which is acquired by the ultrasound element or the image sensor element, and that generates a three-dimensional image based on the two-dimensional image. The image processing unit includes a storage unit that stores position correspondence information and/or image correspondence information, and a control unit that determines a position inside the three-dimensional image corresponding to a current position of the ultrasound element or the image sensor element, based on the position correspondence information or the image correspondence information, and that generates display information in real time, in which the determined position inside the three-dimensional image is identified and displayed inside the three-dimensional image.
