Roentgen detector system for dual radiation source-multilayer-spiral computer tomography device, has two roentgen detector units, where one detector in measuring range has confined measuring field range in azimuth direction

摘要

The system has two roentgen detector units (22, 23), where one detector in measuring range that runs parallel to a rotational axis (z) of the system has a confined measuring field range in azimuth direction running perpendicular to the axis when compared to another detector measuring range that runs perpendicular to the former detector measuring range. The azimuth direction is determined by the circumferential direction of a circuit at a roentgen source (27) that is arranged diametrically opposite to the roentgen detector unit (22) with respect to the axis.
