The purpose of our research is to develop a new myocardial single photon emission CT (SPECT) system with a semiconductor detector. The gamma camera with a semiconductor detector enables us to measure projection data with arbitrary angles because the detector is smaller than that in ordinary gamma cameras with a scintillation detector. We have proposed a new data acquisition method for a myocardial...
In this study, which is based on data collected from 1351 referred patients, we used myocardial perfusion single-photon emission computed tomography (SPECT) for risk stratification before non-cardiac surgery. We generated binary classifiers using support vector machine (SVM) and conventional linear models for predicting perioperative cardiac events. Input data comprising clinical and surgical risk...
We have developed digital phantoms to be used for a basic education on an image quality and a quantification of SPECT data. Differing from the digital phantoms developed by Castiglioni and et al, several SPECT projection data sets were generated by Monte Carlo simulations (EGS4 code) with different acquisition parameters. A physical, brain and cardiac phantoms were generated. An external shape of...
