  • Patent number: 9084541
    Abstract: According to one embodiment, an input unit repeatedly inputs a trigger signal originating from a specific cardiac phase from an electrocardiograph. An RR period determination unit determines whether the period between the input time point of the latest trigger signal, of repeatedly input trigger signals, and the input time point of an immediately previously input trigger signal is equal to or more than the preset first threshold, for each input of the latest trigger signal. A scan control unit terminates the generation of X-rays, if it is determined that the period is equal to or more than the first threshold.

  • Publication number: 20130251096
    Abstract: According to one embodiment, an X-ray CT apparatus includes units. The unit calculates an arrhythmia index. The unit selects a normal mode or an arrhythmia mode based on the arrhythmia index. In the normal mode, after the elapse of a predetermined delay time from the characteristic wave, projection data is collected along with X-ray generation. Upon detecting an arrhythmia, the X-ray generation is temporarily stopped. In the arrhythmia mode, after the elapse of the predetermined delay time, projection data is collected along with X-ray generation. Upon detecting an arrhythmia, an arrhythmia scanning procedure corresponding to an arrhythmia type is temporarily executed, and projection data is collected along with the X-ray generation.

  • Patent number: 8094775
    Abstract: An X-ray computer tomography apparatus includes an X-ray tube, a two-dimensional array type X-ray detector, a rotating mechanism, a pair of collimators, a collimator moving mechanism which separately moves the pair of collimators in a direction almost parallel to a rotation axis, a reconstruction processing unit which reconstructs image data in a reconstruction range, and a collimator control unit. The collimator control unit controls the position of each collimator in accordance with the distance between an X-ray central plane corresponding to a cone angle 0° and an end face of the reconstruction range. The collimator moving mechanism moves each of the pair of collimators in the range from the outermost position corresponding to the maximum cone angle to the innermost position offset from a position corresponding to a cone angle of nearly 0° to the opposite side.

  • Patent number: 6188744
    Abstract: A plurality of regions of interest can be set to be monitored. From a keyboard (17) or a mouse (19), ROI position information and CT value conditions for the ROI's are set to a ROI position information memory (39) and a ROI condition memory (21), respectively. An image reconstruction system (9) reconstructs data of a first scan stored in a projection data memory, displays as a reconstruct image (59) on a display device (13) via an image memory (11), and calculates individual representative CT values of the ROI's set as the ROI position information, storing in the image memory (11). A condition decision section (43) of a CPU (15) makes decisions of whether the representative CT values of the ROI's meet the conditions in the ROI condition memory (21), executes an operation between respective results of the decisions to decide whether the first scan is to be continued or shifted to a second scan.
