Application Of The Non-Negative Matrix Factorization Technique To [[C-11]-Dtbz Dynamic Pet Data For The Early Detection Of Parkinson'S Disease
MEDICAL PHYSICS(2014)
摘要
Purpose: To investigate the dependence of the reconstructed image quality on the number of projections in multiprojection Compton scatter tomography (MPCST). The conventional relationship between the projection number used for reconstruction and reconstructed image quality pertained to CT does not necessarily apply to MPCST, which can produce images from a single projection if the detectors have sufficiently high energy and spatial resolution.
