    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.

    摘要: 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.
