- 《Physics in Medicine & Biology》 被引量: 91发表: 1986年 Calibration Method for ML Estimation of 3D Interaction Position in a Thick Gamma-Ray Detector. High-energy (> 100 keV) photon detectors are often made thick relative to their lateral resolution in order to improve their photon-...
Monolithic CdZnTe gamma-ray detectors are used to build gamma cameras for nuclear medicine imaging but their energy resolution is currently limited by charge sharing between adjacent anodes. For this work, charge sharing is simulated using Ulysse, a numerical model that takes into account the ...
Gamma-ray imaging probes. 来自 掌桥科研 喜欢 0 阅读量: 20 作者: WJ Wild 摘要: External nuclear medicine diagnostic imaging of early primary and metastatic lung cancer tumors is difficult due to the poor sensitivity and resolution of existing gamma cameras. Nonimaging counting detectors used for ...
Gamma rays in this energy range can also be efficiently stopped, and therefore measured by external detectors. Most human imaging procedures with radioactivity are accomplished using 99mTc, which emits a 140 keV gamma ray during decay. 99mTc has a 6 h half-life and is continuously available from...
