摘要： Upon successively acquiring a plurality of tomographic images of an identical patient, and displaying them time-serially, the display mode of images is changed. More specifically, the display order of images is switched in correspondence with the standing position of the observer. The standing position of the observer can be automatically detected. The aperture width of a precollimator is controlled in accordance with the setups of images of interest/non-interest, and data from predetermined detection element arrays are bundled in accordance with the setups. At least one of a plurality of reconstructed tomographic images and a specific image undergo a differential process to generate and display a differential image. The pixel values of at least one of a plurality of reconstructed tomographic images are compared with a predetermined threshold value to generate and display an image consisting of only pixels that have exceeded the threshold value.

摘要： A rotation frame supports an X-ray tube and an X-ray detector to be rotatable about a rotation axis. A top plate support mechanism supports the top plate on which a sample is placed to be movable along the rotation axis. A scan controller drives the top plate support mechanism and the rotation frame so as to scan a plurality of scan areas either partially overlapping or being adjacent along the rotation axis with the X-rays. A reconstruction processor generates a plurality of volume data sets corresponding to the plurality of scan areas on the basis of the output from the X-ray detector. A boundary corrector corrects CT values of the plurality of volume data sets on the basis of CT value differences between the overlapping or adjacent portions of the plurality of volume data sets.

摘要： According to one embodiment, an X-ray computed tomography apparatus includes an X-ray tube, X-ray detector, acquisition unit, rotating mechanism, input unit, and control unit. The input unit repeatedly inputs trigger signals originating from a specific phase of a periodic motion of a body of a subject or a periodic motion of an organ of the subject. The trigger signals being supplied from a measuring device which measures the periodic motion. The control unit causes the X-ray tube to start generating X-rays on the basis of the input of a first trigger signal of the repeatedly input trigger signals, and causes the X-ray tube to stop generating X-rays on the basis of the input of a second trigger signal next to the first trigger signal in order to repeatedly scan the subject over substantially one period of the movement while a scan position is fixed.
