Abstract
Official abstract text for this publication.
A method for extracting photon depth of interaction information in a positron emission tomography system is provided. A pulse is detected in a photodetector. A height of the pulse is measured. A determination of whether the pulse height is within a set range is made. Photon depth of interaction is extracted from the pulse height. An energy of interaction is calculated from the pulse height and calibration data. The extracted photon depth and calculated energy spectrum are used in image reconstruction.
First claim
Opening claim text (preview).
The invention claimd is: 1. A method for extracting photon depth of interaction information in a scintillator crystal of a positron emission tomography system, wherein the scintillator crystal has a rod-like shape with a length with a single photodetector at a first end of the length and a light absorbing coating at a second end of the length and a uniform reflective coating on sides of the scintillator crystal extending from the first end of the length to the second end of the len…
