Point-Source Measurements using a Dome Shaped CsI Detector for Cardiac SPECT
We present feasibility studies of an economically built curved CsI dome for a high performance Cardiac SPECT application. The dome CsI was 99% of standard CsI density and mechanically stable. The light yield was 56% of a standard CsI crystal. Subsequently we successfully performed point-source position-sensitive scintillation light measurement experiments on a CsI:Tl domed sample, with a simple fiber-optic readout. The economical technique of building the detector shown here will be investigated further over the long term future.
