    摘要： An X-ray CT system includes a fixed frame portion and a rotating frame portion. Being provided with X-ray tubes, the rotating frame portion is arranged so as to rotate with respect to the fixed frame portion. Vane members for feeding air are secured on the rotating frame portion. In operation, with the rotation of the vane members together with the rotating frame portion, cool air is introduced into the rotating frame portion. Consequently, heated instruments, such as the X-ray tubes, in the rotating frame can be cooled down effectively.

    摘要： There is disclosed an X-ray computerized tomography apparatus capable of accurately and promptly carrying out a navigation of an operation, by real-time reconstructing and displaying an image of a slice in which an object such as an insertion object inside a subject exists. This X-ray computerized tomography apparatus is structured to include: an X-ray detection unit for detecting transmission X-rays from a plurality of directions Irradiated from an X-ray beam generation source and transmitted through a subject, a data acquisition unit for acquiring transmission data according to the transmission X-rays detected by the X-ray detection unit, an object position detection unit for detecting a position of an object inside the subject, according to a part of the transmission data, a reconstructing range determining unit for determining a slice to be image-reconstructed, according to the position detected by the object position detection unit, and an image reconstruction unit for reconstructing a tomographic image of a slice in which the object exists, according to a transmission data acquired by the data acquisition unit, the transmission data being acquired in the slice. Thus, the X-ray computerized tomography apparatus directly detects the position of the object from the acquired transmission data, and controls the image reconstruction, display or scanning, based on the detected position.

    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.
