Patent ID: 7372035

Claim:
A radiological imaging apparatus comprising: a plurality of semiconductor radiation detectors each having a semiconductor member and first and second electrodes provided on the semiconductor member so as to sandwich the semiconductor member between the first and second electrodes, the first electrodes being arranged opposite each other in an arrangement extending in one direction so that the first electrodes are not electrically connected together, the second electrodes being arranged opposite each other in the arrangement extending in one direction so that the second electrodes are electrically connected together in a DC manner; first waveform shaping devices each provided for the first electrodes of a plurality of the semiconductor radiation detectors within the arrangement to execute a waveform shaping process on an output from each first electrode; second waveform shaping devices each connected to the second electrodes of a plurality of the semiconductor radiation detectors electrically connected together within the arrangement to execute a waveform shaping process on an output from each second electrode; and a signal processing device to which outputs from the first waveform shaping devices and second waveform shaping devices are input, and wherein a shaping time required for the second waveform shaping device to execute the waveform shaping process is set shorter than that required for the first waveform shaping device to execute the waveform shaping process.
