The Compton camera: A challenge in making new apparatus for nuclear medicine.
The term nuclear medicine is commonly used to describe method by which a patient is administered a radioactive trace element. After entering the body, the trace element is attracted by certain cells, i.e. tumours. By detecting the gamma radiation escaping the body, the location of the cells can be determined. Current methods suffer from poor efficiency in detecting the radiation due to the use of mechanical collimators. In the Compton Camera the mechanical collimators is to be replaced by electronic means. This however poses a great challenge on the detection system. IDE AS is together with the University of Michigan, Department of Medical Physics and the European Laboratory for High Energy Physics, CERN, involved in the development of the detector elements and the readout electronics
The possible theses work would be:
Characterisation of multi-channel silicon detectors and electronics
for use in the Compton Camera. The work would consist of setting
up an
experiment to determine the energy and position resolution of a multi-channel
silicon detector. The person would himself design and make part of the
equipment and analyse the results for suitability of the detectors in the
Compton Camera. Some knowledge of electronics would be beneficial. Characterisation
and evaluation of the use of multi channel silicon detectors for detection
of scintillation light from CsI scintillation crystals could as well be
part of the work.
Development and design of the camera head and integration with the data-acquisition system. The work would involve mechanical and electronic design of the front-end modules for the camera. The challenge is to integrate the detectors, electronics and mechanics into a confined space while maintaining the required performance
Development of hardware and software for data-acquisition and
triggering. The readout of the camera-head will be by means of
software running in multiple Digital Signal Processors. The challenge is
to develop fast and efficient code for the first level reconstruction.
The main work would have to be carried out at IDE AS located at Høvik,
near Oslo, Norway or at CERN.
IDE AS is a producer of state-of-the-art electronics for radiation detection. The company was founded in 1992. IDE AS employs today 18 persons. Among the customers are CERN, NASA, Universities in Europe, USA and companies making radiation detection devices.
