摘要:
An extraction unit extracts a centerline of a tubular structure from a volume data set. A generation unit generates a plurality of image data sets concerning a plurality of curved planes based on the volume data set. Each of the curved planes contains the centerline. The plurality of image data sets have a plurality of image lengths respectively and contain a plurality of centerlines respectively. A first specification unit specifies a first image data set or a second image data set from the plurality of image data sets. The first image data set is specified based on the plurality of image lengths of the plurality of image data sets. The second image data set is specified based on gradients of the plurality of centerlines of the plurality of image data sets. A display unit displays the first image or the second image.

An X-ray perfusion-image creating unit creates an X-ray perfusion image indicating blood flow dynamics in a certain organ from an X-ray projection image of a subject given with a contrast agent. An image correction unit extracts thickness information indicating the thickness of a myocardium from a three-dimensional image taken by an X-ray Computed Tomography (CT) apparatus. Moreover, the image correction unit creates a corrected perfusion image in which the thickness of the myocardium in the X-ray perfusion image is corrected, based on the thickness information. A display unit then displays the corrected perfusion image.

In an image processing system according to an embodiment, an image processing device in the embodiment includes a receiving unit, a flat image generator, and an output unit. The receiving unit receives setting of a region of interest on parallax images of a subject that are displayed stereoscopically. The flat image generator generates a flat image of a cut surface of the subject that is generated by cutting the subject along a plane corresponding to the region of interest received by the receiving unit based on volume data of the subject stored in a predetermined storage device. The output unit outputs the flat image generated by the flat image generator.

An X-ray CT apparatus includes a perfusion data acquisition unit, a perfusion parameter calculating unit and a perfusion parameter display unit. The perfusion data acquisition unit generate perfusion data by exposing an X-ray to the object with injecting contrast medium. The perfusion parameter calculating unit calculates perfusion parameters corresponding to ROIs based on time variations in density of the contrast medium for the ROIs. The perfusion parameter display unit divides a period to be a calculation target of the time variations into plural time ranges and sequentially displays images each including the ROIs. The images correspond to the time ranges and mutually different time phases respectively and are masked so as to make only ROIs at which the perfusion parameters show values displayed.
