Abstract
A method of locating an event with a gamma camera () of an emission computed tomography (ECT) scanner () is provided. The gamma camera () includes a matrix of sensors () situated to view the event. The sensors () have respective outputs that are responsive to the event. The method includes: identifying a first sensor in the matrix that has in response to the event a highest output relative to the other sensors in the matrix (step (B)); identifying a number of second sensors in the matrix that are closest neighbors to the first sensor (step (B)); combining into a total output a number of outputs from the identified sensors, the number of outputs being at least one (1) and less than the number of all the identified sensors (step (B)); and, determining a threshold value which is a percentage of the total output (step (B)).
