Abstract:
1. A method of generating a diagnostic image with a gamma camera of an emission computed tomography (ECT) scanner, said gamma camera including a matrix of sensors situated to view the event, said sensors having respective outputs that are responsive to the event, said method comprising: (a) 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; (b) identifying a sensor in the matrix that has, in response to the event, a third highest output relative to other sensors in the matrix; (c) based on the first and third highest outputs, determining a number of second sensors in the matrix that are closest neighbors to the first sensor and identifying such second sensors; (d) sampling outputs from the identified first and second sensors, said number of outputs being at least three and less than the number of all the identified sensors; (e) determining an event location with the sampled outputs; (f) repeating steps (a)-(e) to determine a plurality of event locations; (g) forming the plurality of event locations into a human viewable image.
