Arrangement for producing a body section image

摘要

The invention relates to a computer tomograph. According to the invention, the detector system (10) contains detectors (12) made of cadmium telluride CdTe or bismuth germanium oxide Bi12GeO20, whose temperature during operation is at least 40 DEG C, preferably at least 60 DEG C and particularly preferably at least 70 DEG C. By virtue of the temperature increase, the storage effect produced by traps in the semiconductor body is avoided. The output signal of the detector system (10) thus takes the form of electrical pulses which are proportional to the absorption of the rays (4) in the sectional plane through the body.
