The existing SPECT system for nuclear cardiac imaging suffered from low sensitivity or high cost. In this study we implemented a novel design of the stationary dedicated cardiac SPECT combined with multi-pinhole collimators based on the clinical dual-head scanner with low cost. Previous simulation study has demonstrated the feasibility of the design. Accurate geometry calibration was implemented for...
In this study we proposed a novel design of the stationary multi-pinhole dedicated cardiac SPECT based on clinical dual-head scanner with high sensitivity and low cost for nuclear medicine myocardial perfusion imaging.
The objective of this study was to develop a maximum likelihood gamma positioning method (MLGPM) with accurate calibration of the mean detector response function (MDRF) and the statistics of output from PMTs and the next stage data acquisition electronics in a clinical SPECT detector.
In this study, animal SPECT imaging functionality was developed in Nucmed Inliview 3000 PET/SPECT/CT system with an elliptical-pinhole collimator in the shared PET/SPECT ring detector. The collimator was designed to allow simultaneous PET/SPECT dual-tracer imaging. It contains 5 pinhole rings with 10 pinholes per ring. The transverse plane of pinhole was designed to be elliptical to reduce the axial...
We describe a single photon emission computed tomograph (SPECT) which can be operated inside state-of-the-art magnetic resonance imaging (MRI) systems. The combined SPECT/MRI system allows one to acquire simultaneously the data from both modalities and co-register the images in space and time. The new SPECT is based on the semiconductor cadmium zinc telluride (CZT) and application specific integrated...
