Abstract
A detector arrangement (10) for detecting and transferring detector signals to a processing unit is described. This detector arrangement is provided in particular for use in a computer tomograph for high-resolution detection of X-rays, the processing unit being in the form of a central processing unit or buffer memory (Z) on a rotatable portion of a gantry (1). To transfer the detector signals with the minimum number of contacts or plug-in connectors also in the case of a high-resolution detector arrangement (10), this comprises at least one detector module having a plurality of individual detector elements as well as an electrical unit having an electro-optical transducer for processing the signals of the detector elements and for generating optical detector module output signals.
Claims19
A detector arrangement comprising:
- at least one detector module having a plurality of individual detector elements, which detect radiation and generate signals indicative of the radiation, the at least one detector module comprising:
- an electrical unit, comprising:
- an electro-optical transducer for processing the generated signals and for generating optical detector module output signals indicative of the generated signals;
- and
- an opto-electrical transducer for processing detector module input signals and supplying the input signals to the detector elements;
- and the at least one detector module further comprising a module carrier having an inner space for the electrical unit and having a cable duct for at least one optical fiber cable.
A method comprising:
- detecting radiation and generating electrical signals indicative thereof with one or more detector elements of a radiation sensitive detector module, where the radiation sensitive detector module comprises a module carrier having a cable duct for at least one optical fiber cable;
- generating optical output signals indicative of the electrical signals using an electro-optical transducer of the radiation sensitive detector module;
- and
- supplying input signals to an opto-electrical transducer of the radiation sensitive detector module for the detector elements of the radiation sensitive detector module.
A detector module for an imaging system, comprising:
- one or more detector elements;
- an electro-optical transducer that generates optical output signals indicative of radiation detected by the one or more detector elements;
- an opto-electrical transducer that receives input signals and supplies said signals to at least one of the detector elements;
- and
- a module carrier having an inner space for the electro-optical transducer and the opto-electrical transducer and having a cable duct for at least one optical fiber cable.
