摘要： An X-ray CT apparatus has a scanner, a pre-scan control unit, an image generating unit, a region setting unit and a timing sensing unit. The pre-scan control unit controls an operation of the scanner to perform a pre-scan. The image generating unit generates image data of the object based upon the pre-scan. The region setting unit sets, on the basis of the image data, a region of interest, and a larger region encompassing the region of interest and a region around the region of interest and being used to determine whether or not a high pixel value region exists. The timing sensing unit senses, if the larger region does not include a pixel value higher than a first threshold, a timing to start a main scan, at which a pixel value of the region of interest exceeds a second threshold after injection of the contrast medium agent is started.

摘要： A CT value of an image within a region of interest is calculated with time. While the calculated CT value does not exceed a predetermined threshold value, a reconstruction mode used when an image is reconstructed from projection data is set to half reconstruction. On the other hand, while the calculated CT value exceeds a predetermined threshold value, the reconstruction mode is set to segment reconstruction.

摘要： An X-ray CT apparatus comprises three X-ray generating units, three groups of detecting elements and a reconstructing unit. The three X-ray generating units are arranged so as to make an angle formed by a first X-ray exposure direction and a second X-ray exposure direction on a rotational plane thereof be a same angle as that formed by the second X-ray exposure direction and a third X-ray exposure direction on the rotational plane, the same angle being smaller than 120 degree. The three groups of detecting elements are arranged opposite to the three X-ray generating units respectively so as to make a field of view formed in a center wider than two side fields of view. The reconstructing unit is configured to reconstruct an image using detection data detected by at least desired one of the three groups of the detecting elements.
