Abstract:
1. A computed tomography system comprising: a stationary part; a rotatable part, mounted for rotation around an examination axis relative to said stationary part; an x-ray source mounted on said rotatable part; a radiation detector unit mounted on said rotatable part opposite said x-ray source; a data acquisition unit mounted on said rotatable part and connected to said radiation detector unit for receiving radiation attenuation data from said radiation detector unit; an image reconstruction device that is stationary with respect to said rotatable part; a data transfer device disposed between said data acquisition unit and said image reconstruction device for transferring said attenuation data from said data acquisition unit to said image reconstruction device; a storage unit connected to said data acquisition unit for buffering at least a portion of said attenuation data received by said data acquisition unit before said attenuation data are transferred to said image reconstruction device; and said data acquisition unit comprising a data administration system for transferring a first portion of said attenuation data directly to said data transfer device in real time and for storing a second part of said attenuation data in said storage unit for subsequent transfer to said image reconstruction device via said data transfer device.
