Abstract

According to one embodiment, an X-ray CT apparatus includes a data acquiring unit, a data processing unit and a data transmitting unit. The data acquiring unit is configured to expose an X-ray to an object, acquire detection data of the X-ray having transmitted the object and compress the detection data to generate compressed data. The data processing unit is configured to generate X-ray CT image data of the object based on the compressed data transmitted from the data acquiring unit through a transmission line. The data transmitting unit is configured to transmit uncompressed detection data of an X-ray to the data processing unit through the transmission line according to information from an input device.

Description

technical field [0001] Embodiments of the present invention relate to an X-ray CT (computed tomography, computerized tomography) apparatus and a data transmission method in the X-ray CT apparatus. Background technique [0002] In an X-ray CT apparatus, in order to obtain a three-dimensional and precise tomographic image of a subject, a helical scanning method and a multi-detector method are widely used. Therefore, the rotation speed of the scanner increases, and the number of columns of detectors increases, and the amount of data output from the detectors becomes large. Along with this, it becomes important to suppress an increase in costs for data transfer and data storage in the X-ray CT apparatus. [0003] Therefore, in an X-ray CT apparatus, in order to reduce the amount of data to be transmitted, it has been proposed to output data from a gantry rotating unit on the detector side in a data acquisition unit (DAS: Data acquisition system, data acquisition system). A met...
