Using Rose's metal alloy as a pinhole collimator material in preclinical small-animal imaging: A Monte Carlo evaluation.

Abstract
Pinhole collimation is the most common method of high-resolution preclinical single photon emission computed tomography imaging. The collimators are usually constructed from dense materials with high atomic numbers, such as gold and platinum, which are expensive and not always flexible in the fabrication step. In this work, the authors have investigated the properties of a fusible alloy called Rose's metal and its potential in pinhole preclinical imaging. When compared to current standard pinhole materials such as gold and platinum, Rose's metal has a lower density and a relatively low effective atomic number. However, it is inexpensive, has a low melting point, and does not contract when solidifying. Once cast, the piece can be machined... (More)

The aim of this study was to evaluate the imaging properties for Rose's metal and compare them with those of standard materials. (Less)
