The use of narrow scintillators in imaging devices raises the question of whether there is enough light output that can yield reasonable energy and spatial resolutions. Compared to scintillation within large-area detectors (such as those used in conv

Optimization of high energy collimator design

Multi-hole collimators are the most important piece of instrumentation in determining the trade-off between spatial resolution and noise of nuclear medicine images. Recently, we discovered that the collimator-to-detector gap influences very much the

Simulation of SPECT imaging with converging-hole collimators

Autor: X. Yu, D.L. Gunter

Publikováno v: IEEE Conference on Nuclear Science Symposium and Medical Imaging.

The authors have developed a computer program that simulates the images acquired in SPECT (single photon emission computed tomography) using a gamma-ray camera with a converging-hole collimator and following complex orbital trajectories. The nonstati
