Collimators for an array of radioactive lines for use on a spect system for non-uniform attenuation correction measurements

摘要

According to the present invention, an improved source collimator for use in nuclear medicine imaging is provided. The improved source collimator utilizes a larger collimation angle than has previously been used in the art. The use of the larger collimation angle for the source collimator reduces the sensitivity of the nuclear medical imaging systems to misalignment between the detector and the source collimators.
