Abstract: A processor analyzes an image obtained by imaging a subject including a tubular structure in which a fluid flows, thereby deriving fluid information regarding flow of the fluid at each of pixel positions in the tubular structure. The processor derives, within the tubular structure included in the image, a matching degree between the fluid information at a plurality of pixel-of-interest positions set at a first sampling interval and the fluid information at a plurality of pixel positions within a predetermined region based on the pixel-of-interest positions. The processor sets a second sampling interval for displaying the fluid information in accordance with the matching degree. The processor samples the fluid information at the set second sampling interval and causes a display to display the fluid information.

Abstract: A first registration unit performs first registration between a live view and an associated image associated with an object to be imaged. A second registration unit performs second registration between the object captured in the live view and the associated image based on the result of the first registration. At least while the second registration is performed, a display control unit superimposes the associated image on the object captured in the live view, and displays an enlarged view of a partial region of the live view, on which the associated image is superimposed. The second registration unit performs the second registration using a region of the live view larger than the partial region while the enlarged view of the partial region of the live view is displayed.

Abstract: A processor analyzes an image obtained by imaging a subject including a tubular structure in which a fluid flows, thereby deriving fluid information regarding flow of the fluid at each of pixel positions in the tubular structure. The processor sets a sampling interval for displaying the fluid information in accordance with a size of a region intersecting a center line of the tubular structure included in the image. The processor samples the fluid information at the set sampling interval and causes a display to display the fluid information.

Abstract: An image acquisition unit acquires a phase contrast image consisting of a plurality of phases for each of three spatial directions, in which a pixel value of each pixel represents a velocity of fluid for each of the three directions, the phase contrast image being acquired by imaging a subject including a structure inside which fluid flows by a three-dimensional cine phase contrast magnetic resonance method. An identification unit identifies a region of the structure in the phase contrast image on the basis of a maximum value of the velocity of the fluid between corresponding pixels in each of the phases of the phase contrast image.

Abstract: There is provided an image registration device, method, and program that enable easy and quick initial registration between a target part included in an intraoperative video and simulation information, such as a simulation image. A first registration unit performs initial registration between an intraoperative video and simulation information. At this time, an intraoperative image for registration in an intraoperative video is displayed on a display. An operator performs registration between a target part included in the intraoperative image and the simulation information. After the end of initial registration, a second registration unit performs second registration between the simulation information and the target part included in the intraoperative video based on the result of the initial registration.

Abstract: In a craniotomy simulation device, method, and program, a path to an abnormal area can be efficiently determined for a simulation of a craniotomy. A path derivation unit derives, in a three-dimensional image of a brain of a subject including an abnormal area, at least one path from the abnormal area to a surface of the brain through a cerebral sulcus in the brain. A craniotomy pattern setting unit sets a craniotomy pattern for tracing the path, on a surface of a head of the subject included in the three-dimensional image.

Abstract: The invention provides a fluid analysis apparatus, a method for operating a fluid analysis apparatus, and a fluid analysis program that perform display such that the tendency of a fluid flow in a blood vessel is easily checked. Route position information that is capable of identifying an order along a route of the anatomical structure is assigned to each position in the anatomical structure, using three-dimensional volume data in which each voxel has the information of a three-dimensional flow velocity vector indicating a flow velocity of a fluid in an anatomical structure. The three-dimensional flow velocity vector is selected such that the route position information of a position where the three-dimensional flow velocity vector is present is sequentially arranged from one point in the anatomical structure and a trajectory indicating the flow of the fluid is drawn so as to be visibly recognized.
