A practical triple energy window technique (TEW) is proposed, which is based on using the information in two lower energy windows and one single calibration to estimate the scatter within the photopeak window. In order to evaluate the technique, a Monte Carlo simulation program which simulates the PENN-PET University of Pennsylvania positron emission tomography scanner geometry was used. Different phantom activity distributions and phantom sizes were tested to simulate brain studies including uniform and nonuniform distributions. The results from simulated data indicate that the TEW technique works well for a wide range of activity distributions and object sizes. The preliminary comparison between the TEW and dual window techniques shows better quantitative accuracy for the TEW, especially for the nonuniform distribution phantoms.<<ETX>>
