Improved modeling of system response in list mode EM reconstruction of Compton scatter camera images
Publikováno v:
IEEE Transactions on Nuclear Science. 48:111-116
An improved List Mode EM method for reconstructing Compton scattering camera images has been developed. First, an approximate method for computation of the spatial variation in the detector sensitivity has been derived and validated by Monte Carlo co

A Compton camera is being tested for nuclear medicine applications. Our design uses a single 3 cm by 3 cm silicon pad detector as the first detector system, and SPRINT, an array of position-sensitive sodium iodide modules, as the second detector. Exp

Compton cameras decouple the inverse relationship between spatial resolution and detection sensitivity which compromises the performance of conventional collimated cameras. However, this improvement is usually achieved at the expense of the amount of

Theoretical studies show our prototype Compton camera, C-SPRINT, matches the 99m Tc performance of clinically available mechanically collimated systems if an advantage in sensitivity of ∼45 can be achieved. Imaging at higher energies substantially

An electronically-collimated imaging system is being built using pixellated, low-noise, position-sensitive silicon as the first detector, and a sodium iodide scintillation detector ring as the second detector. The system consists of a single 3/spl ti

Using the Uniform Cramer-Rao bound on variance, the performance of a conventional parallel-hole collimator has been compared with that of a ring-geometry Compton-scatter aperture. Objects used for the evaluation were uniformly emitting disk sources w
