ABSTRACT:
A medical radiological diagnostics system having an automatic exposure unit employs signal acquisition and a processing circuitry for controlling the radiation source so as to obtain easily diagnosed exposures with a low radiation load. This is accomplished by disposing a stray radiation grid between the radiation receiver and a radiation sensor, or by selecting the spacing between the radiation receiver and the radiation sensor such that scattered radiation is not incident on the radiation sensor, or, in a system having an x-ray image intensifier and a light sensor, by supplying the output signal of the light sensor to the control circuit through a high-pass filter. In all versions, the measured signal is not disadvantageously influenced by scattered radiation, so that a correct exposure of x-ray film is possible.
