    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.

    摘要： An X-ray detection system has a detector and a data acquisition unit. The detector detects an X-ray passing through a body and producing an analog electric signal for each channel. The data acquisition unit includes a plurality of circuit blocks each including as many circuits as the number of channels assigned to each block. The data acquisition unit converts the analog electric signal into a digital signal for each channel and outputs the resultant digital signal. A phase control unit controls the phase of the circuit blocks such that the circuit blocks are grouped into a plurality of groups. The respective groups operate in synchronization with clock signals for the data acquisition unit. Phases of the clock signals are mutually different at least between two groups.

    摘要： A diagnostic system is provided to display images in an image-display order complying with a desired scan direction in performing a multi-scan. The system is realized by, by way of example, an X-ray CT scanner. The diagnostic system has a display unit, an element performing scanning with an object to acquire data therefrom, an element producing a plurality of images from the data in a production order, an element displaying on the display unit the plurality of images in a display order, and an element for setting the production order or display order. The production or display order is set in accord with a scan direction along which the slice positions are moved every scan. The production order is, for example, a reconstruction order of the images. The image reconstruction based on the reconstruction order results in that images are displayed in that order, i.e., in an order complying with the scan direction. Of course, the display order itself is set, the images are displayed in that order, i.e., in an order complying with the scan direction.
