Imaging Systems

radimg_1The images on this page show actual gamma-ray images of various source types and geometric arrangements, which are shown schematically before their respective images. These gamma-ray images were created using the detector shown to the left. Each image has a caption giving a full description of what is shown.

Many of developments in radiation imaging date back over 30 years to our involvement with Nuclear Medicine in the development of instrumentation for gamma-ray imaging. Since the medical instrumentation industry represents one of the largest commercial outlets for radiation instrumentation, we expect that our present involvement in this area will continue to grow in the foreseeable future. The present annual market of about $500M per year in gamma-ray imaging devices will continue to serve as a powerful driver in the evolution of the technology.

Most recently, we have been active in the development of Compton scattering techniques that avoid the efficiency loss due to the collimator in conventional gamma-ray cameras. While there appears to be fundamental limits in the use of this technology at the low gamma ray energies currently predominate in nuclear medicine studies, there would be decided advantages in their application to higher energy gamma rays in either a medical or industrial context. There is a great deal of interest in techniques for higher energy gamma ray imaging for use in the decontamination of nuclear facilities or in fast neutron imaging for the detection of clandestine nuclear materials. For these reasons, it is likely that imaging studies will remain an important research component in the years ahead.
