Penetration and scatter in channel micro-pinholes for SPECT: a Monte Carlo investigation

Abstract

Pinhole SPECT is rapidly gaining popularity for imaging laboratory animals. High resolution images can be achieved by using small pinhole diameters, but micro-pinhole images have higher contributions of penetrated and scattered photons. A characterization of penetration and scatter in the pinhole aperture metal can be used in the design of small animal… (More)
