Abstract :
The concept of positron transmission tomography is described. The signal-to-noise ratio of measured positron transmission raysums is two times better than that of conventional single gamma transmission. Ageing of the source does not change calibration of measurement because the intensity of the source is determined during every sampling period. Focusing of the transmission beam can be made electronically. Information containing in scattered events can be processed.
