摘要： An X-ray CT apparatus detects a predetermined characteristic wave from each electrocardiographic waveform acquired from an electrocardiograph, predicts intervals with which the characteristic wave appears based on appearance times of the detected predetermined characteristic wave in each electrocardiographic waveform, and determines an X-ray irradiation start time based on the predicted interval time. After an instruction to start collection of X-ray intensity distribution data is received, if an appearance interval of a detected predetermined characteristic wave is within an acceptable normal-heartbeat range, it is determined as a normal heartbeat. If the appearance interval of the detected predetermined characteristic wave is outside the acceptable normal-heartbeat range, it is determined as an abnormal heartbeat. During a period after receiving the instruction to start the collection until reaching a time of starting the collection of X-ray detection information, when determined as an abnormal heartbeat, an X-ray irradiation start time is recalculated, and then determined.

摘要： A condition on the attribute of an image for generating multi-frame image data containing a plurality of frames of images per file from image data is stored beforehand. When image data is received, multi-frame image data is generated from the received image data based on incidental information contained in the image data and the condition stored beforehand. Then, the generated multi-frame image data is archived. When a request for an image is made by a certain terminal, an application functioning on the terminal is identified, and multi-frame image data appropriate for the application is sent from among the generated multi-frame image data.

摘要： A medical image diagnostic apparatus according to an embodiment includes a simplified positron emission computed tomography (PET) image data generating unit, a PET image data generating unit, and a display. The simplified PET image data generating unit generates simplified PET image data based on information obtained by projecting the position of a generation source of a gamma ray emitted from a subject to whom a radioisotope is administered onto a predetermined projection surface in a predetermined direction. The PET image data generating unit generates, based on an evaluation result of the simplified PET image data, PET image data by using projection data in the PET imaging mode generated based on a detection result of the gamma ray emitted from the subject. The display displays the simplified PET image data and the PET image data.
