Gamma camera with two sequential correction maps

摘要

A method of correcting errors in imaging data in a Gamma Camera including determining a first correction map based on one or both of (1) calculated corrections and (2) a first data acquisition, determining a second correction map based on a second data acquisition and correcting the imaging data based on the first and second correction maps. In a preferred embodiment of the invention, error correction is implemented using a neutral network. Alternatively, a neural network can be used to perform the entire calculation of event position and/or energy.
