Test method for testing the quality of a detector module for an X-ray computer tomograph involves measurement of X-radiation with reference and test modules and then comparison and evaluation of their output signals

摘要

Method for testing the quality of a detector module for an X-ray computer tomograph has the following steps: provision of a measurement arrangement including X-ray source (4), reference detector module (3) and recording arrangement (1) in which the detector module to be tested is inserted; irradiation of the reference detector module and the detector (D) containing the under-test detector module and; measurement and comparison of reference and test module signals. The invention also relates to use of a X-ray computer tomograph gantry and test gantry for testing detector modules.
