Abstract
A collimator system rotatable about an axis of rotation for use in a radionuclide emission tomography camera for imaging a region of an object, including a collimator having a number of collimator elements for restricting and collimating the radionuclide emissions. The collimator elements are disposed with their axes intersecting at least one line, parallel to the axis of rotation, at at least two different angles. The collimator elements establish a selected variation in imaging sensitivity across the imaging region.
