The methodology of PET image remote transfer by Internet has been explored. The original images were acquisited with ECAT EXACT HR+ PET

and then converted to Dicom format by Mview software. The Dicom images were transferred via Internet. Thus the PET images were transferred via Internet successfully. The ideal images were obtained away from 8 km. The transfer time of brain and whole body image was (37±3) s and (245±10) s respectively

while the transfer rate was (34.7±2.8)kbyte/s and (34.4±1.5)kbyte/s

respectively. The results showed that the remote transfer via Internet was feasible and practical.
