摘要： A CT value of an image within a region of interest is calculated with time. While the calculated CT value does not exceed a predetermined threshold value, a reconstruction mode used when an image is reconstructed from projection data is set to half reconstruction. On the other hand, while the calculated CT value exceeds a predetermined threshold value, the reconstruction mode is set to segment reconstruction.

摘要： An image processing system according to an embodiment includes a display unit capable of displaying stereoscopic images by displaying a group of parallax images and a display control unit. The display control unit displays an operation screen for receiving operations on medical image data on the display unit, displays selection information for selecting medical image data on the operation screen, and controls whether the selection information will be displayed as a stereoscopic image or a planar image depending on the content of medical image data selected by the selection information.

摘要： An image diagnostic apparatus of an embodiment includes a density change acquisition unit, a trigger generating unit and a control unit. The density change acquisition unit is configured to acquire data corresponding to a temporal change in density of a contact agent injected into an object. The trigger generating unit is configured to generate a trigger when abnormal data has been detected by a first threshold processing of the data. The trigger is generated by a second threshold processing of data other than the abnormal data. The control unit is configured to perform a control of contrast imaging for the object based on the trigger.

摘要： An X-ray CT apparatus sets at least an imaging-subject area to be imaged, and a heart imaging area included in the imaging-subject area and determined based on a position and size of a heart on a subject P. When an image is taken, the X-ray CT apparatus sets imaging conditions, such as whether electrocardiographic synchronization is required for imaging and a type of reconstruction mode, based on each set imaging area.

摘要： An X-ray CT apparatus has a scanner, a pre-scan control unit, an image generating unit, a region setting unit and a timing sensing unit. The pre-scan control unit controls an operation of the scanner to perform a pre-scan. The image generating unit generates image data of the object based upon the pre-scan. The region setting unit sets, on the basis of the image data, a region of interest, and a larger region encompassing the region of interest and a region around the region of interest and being used to determine whether or not a high pixel value region exists. The timing sensing unit senses, if the larger region does not include a pixel value higher than a first threshold, a timing to start a main scan, at which a pixel value of the region of interest exceeds a second threshold after injection of the contrast medium agent is started.
