A coded aperture for high-resolution nuclear medicine planar imaging with a conventional Anger camera: experimental results
TL;DR: In this paper, a coded aperture camera was designed for high-resolution (1.66-mm) imaging of low energy (140 keV) gamma-ray emitters with a conventional camera.
Journal ArticleDOI
Development and validation of a Monte Carlo simulation of photon transport in an Anger camera
D.J. De Vries,Stephen C. Moore,Robert E. Zimmerman,S. P. Mueller,Bernard Friedland,Richard C. Lanza +5 more
TL;DR: A Monte Carlo simulation of photon transport which includes collimator scatter is developed and Comparisons of measured and simulated PSFs demonstrate the validity of the model and the significance of collimators scatter in the degradation of image quality.
Journal ArticleDOI
Optimal coded aperture patterns for improved SNR in nuclear medicine imaging
TL;DR: Simulations of the performance of some coded aperture patterns chosen from different families and the choice of the optimal pattern family are presented with reference to the characteristics of the object to be imaged and in light of the effect of near-field artifacts.
Journal ArticleDOI
Near-field artifact reduction in planar coded aperture imaging
Roberto Accorsi,Richard C. Lanza +1 more
TL;DR: The theory shows that methods used in the past to compensate for the effects of background nonuniformities in far-field problems are also effective in reducing near-field artifacts.

TL;DR: In this paper, the authors present the first dark matter limit from DMTPC from a surface run at MIT, in an analysis window of 80-200 keV recoil energy, based on a 35.7 g-day exposure, they set a 90% C.L. upper limit on the spin-dependent WIMP-proton cross section of 2.0 × 10 − 33 cm 2 for 115 GeV/c2 dark matter particle mass.
