Abstract: A super-resolution processor includes a storage section for storing data of point spread functions of an X-ray CT scanner which are acquired using a phantom and a super-resolution processing section performing super-resolution of image data of a sample generated by the X-ray CT scanner using the stored point spread functions.

Abstract: An X-ray CT apparatus, as one example, includes at least one X-ray irradiation source configured to irradiate an X-ray to a volume of interest, at least one X-ray detector including a plurality of detection element segments configured to detect the X-ray penetrated through the volume of interest, at least one collimator configured to create an opening that is movable in at least one of a slice direction and a channel direction, at least one image processing part configured to extract a portion of the volume data, a controller configured to set the opening of the at least one collimator to a second opening size according to a cylinder-like second scanning range that is set to limit the volume of interest and configured to perform a second scan, and at least one reconstruction part configured to reconstruct image data based on data collected by the second scan.

Abstract: A cerebral ischemia diagnosis assisting apparatus comprises a storing portion for storing multi-slices or volume data with regard to the head portion of a subject, an image generating portion for generating a tomography image of a brain from the multi-slices or the volume data, an image processing portion for processing the tomography image for generating a contrast highlighting image and a brain sulci highlighting image or either thereof, and a display portion for displaying the tomography image along with the contrast highlighting image and the brain sulci highlighting image.
