Abstract
The electric signals for the voltage as a function of distance between Hall devices and permanent magnets over the radial artery were investigated. The electric sgnals, that means signals of arterial pulse wave, were differentiated by the hardware of circuits and then were changed to differential signals as magnetic field. The 3-D images simulated by the software as function fo the intensity of differential signals were achieved. It shows that these system can apply to pulse diagnostic apparatus of porthble type medical instrument.
