New methods of examining gamma camera collimators

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1988

New methods are proposed and described to examine the quality of gamma camera collimators in two special performance categories, namely, uniformity in regional efficiency and regional variations in channel tilt. These two performances are critical areas for SPECT imaging. Results obtained from experimental and commercial collimators illustrate the variability seen for these performance characteristics in currently available collimators.

Development of a portable gamma camera with coded aperture

Nuclear Instruments & Methods in Physics Research Section A-accelerators Spectrometers Detectors and Associated Equipment, 2006

Since the beginning of the 1990s, the CEA is being involved in the development of compact gamma cameras based on a pinhole collimator, a scintillator and an intensified CCD. In collaboration with the Kurchatov Institute, the CEA has recently developed a miniature coded mask, which significantly improves sensitivity and angular resolution. Laboratory tests have demonstrated excellent performance. They are summarized, accompanied with on-site test results. We also present preliminary results of Medipix2/CdTe, a semiconductor pixel detector.
