Abstract:
A computed tomography apparatus comprising:an x-ray source, which generates an x-ray beam that rotates around a system axis; a detector system which rotates around said system axis together with said x-ray source and which detects radiation attenuated by an examination subject during scanning of said examination subject and produces data representing the attenuated radiation; an image reconstruction computer located remote from said detector system and not rotating with said detector system; a data transmission path between said rotating detector system and said image reconstruction computer for transmitting said data from said detector system to said image reconstruction computer; a memory allocated to said detector system for storing said data from said detector system and rotating with said detector system; a data preparation unit allocated to said detector system which rotates with said detector system and which is connected to said memory, said data preparation unit transmitting said data from said memory to said image reconstruction computer via said data transmission path after completion of the scanning, and said data preparation unit extracting, from the data from the detector system, data transmitted during the scanning to the image reconstruction computer via the data transmission path, as extracted data; and a display connected to said image reconstruction computer, said image reconstruction computer reconstructing an image of said examination subject from said extracted data and causing said image to be displayed on said display.
