[Preliminary experience of wireless teleradiology system using Personal Handyphone System]

We investigated the potential of the wireless teleradiology system, using a Personal Handyphone System(PHS) and hand-held personal computer. To provide and interpret CT images, an internet web system was used. It took 5.5 seconds to transmit a single CT image of 28 KB. Therefore, about 2 minutes was required to brawse a series of brain examinations(20 CT images). Although transmission speed needs to be increased, our system makes it possible to perform imaging diagnosis anywhere and is especially useful in emergency situations.
