An Ultrasonic Travel Time Measuring Method for Relative Blood Volume Monitor

Article Preview

Abstract:

This study introduces the basic principle of relative blood volume monitor (BVM) by comparing several ultrasonic travel time measuring methods, brings forth the high-precision ultrasonic travel time measuring method based on TDC-GP2 time measurement chip and MSP430 Single-chip Microcontroller (SCM), presents the configuration of hardware and software in the system, and illustrates the structure and time measurement principle of TDC-GP2 time measurement chip.
