英文摘要	The compressive effect of a magnetic field on the positron range from commonly used positron emitters in pet (positron emission tomography) was simulated using the geant4 toolkit with h2o as the environmental material. the compression of the positron range, which was different in the directions parallel and perpendicular to the magnetic field, showed finite final variation of relative change rate versus the magnetic field. the variation greatly depended on the positron-emission energy spectrum in the same medium. furthermore, the volume of the positron annihilation point was dramatically compressed as the magnetic field was set in the range of 3-6 t. it was more prominent for rb-82, which is generally used as a positron source in pet technology.
