Abstract
Attenuation correction data is obtained from one or more transmission sources to calculate the attenuation factors of a reconstruction area of an object being imaged by a nuclear medicine apparatus, such as a SPECT gamma camera. The transmission sources are capable of swiveling the direction of the transmission to correspond with the direction of capture of the gamma detectors. Additionally, the transmission sources are capable of linear movement to correspond with any linear movement of the detectors. The transmission sources are able to follow the same path as the detectors in order to determine the attenuation factors through the same reconstruction area being scanned by the detectors.
