Abstract
An apparatus for high resolution positron emission tomography (PET) imaging. The apparatus includes at least a first detector and a second detector arranged to detect gamma rays traveling from a target area, the first detector and the second detector being a detector pair. There is at least one collimator for filtering gamma rays reaching the first and second detectors. The collimator defines respective passages filtering gamma rays reaching the respective first and second detectors, the passages being defined to filter for only gamma ray pairs traveling from the target area at a predetermined range of angles with respect to each other, the predetermined range of angles being in the range of 180°-θ, where θis less than 1° and greater than 0°.
