Development of a wavelength-shifting fibre gamma camera

A wavelength-shifting fibre (WSF) gamma camera was built and tested. A spatial resolution of 3.5 mm /spl sim/ 4 mm FWHM was achieved which is comparable to that of modern Anger cameras. Two CsI(Na) crystals were tested and both showed lower light output than expected. Hence a poor energy resolution...

Zusammenfassung:A wavelength-shifting fibre (WSF) gamma camera was built and tested. A spatial resolution of 3.5 mm /spl sim/ 4 mm FWHM was achieved which is comparable to that of modern Anger cameras. Two CsI(Na) crystals were tested and both showed lower light output than expected. Hence a poor energy resolution of 23% FWHM was obtained. Simulation results predict a spatial resolution better than 3 mm if the WSF signals are three times higher than those obtained experimentally. Ways of achieving this goal are discussed.
