摘要： An X-ray computed tomography apparatus of this invention includes a first data detecting system which includes a first X-ray tube and a first X-ray detector and a second data detecting system which includes a second X-ray tube and a second X-ray detector. A reconstructing unit reconstructs image data on the basis of the data detected by at least one of the first and second data detecting systems. A monitoring unit monitors the first data detecting system. In a period during which the first data detecting system is normal, data acquisition is performed by both the first and second data detecting systems. In a period during which the first data detecting system is faulty, data acquisition is performed by the second data detecting system alone.

A blocking member defining a slit structure is provided between the X-ray source and the X-ray detector. The slits of the blocking member include two rows aligned in a channel direction of the detector elements, and two rows staggered in the channel direction, thereby to obtain a CT image with improved spatial resolution.

摘要： An X-ray computed tomography apparatus is provided to reconstruct image data based on projection data acquired by scanning a subject with an X-ray. A calculator is configured to calculate a dose efficiency index based on an expected dose of an X-ray radiated from an input device. The dose efficiency index indicates a diameter of a target which is identified at a predetermined detectability rate and has a predetermined CT value difference with respect to a surrounding CT value. A plan support system is configured to build up a scan planning screen on which the input expected dose is contained along with the calculated dose efficiency index. The scan planning screen is displayed on a display.

摘要： In an X-ray computerized tomography apparatus, a water phantom is interposed between an X-ray tube unit and an X-ray detector in place of a subject under examination and a plurality of pieces of data detected by a plurality of X-ray detector elements are previously measured as a pieces of compensation data while shifting the X-focal point to different positions. Compensation data corresponding to the actual position of the X-ray focal point, which shifts according to the thermal state of the X-ray tube unit, is selected to correct detect data obtained for a subject under examination, permitting optimum compensation of variations in sensitivity among the X-ray detector elements for any position of the X-ray focal point, thereby preventing a ring-like artifact from being produced on a tomography image.
