The Design and Application of Multi-channel Data Collection Board with USB on Medical Instrumentation

Jinwu Qian

Abstract

This paper presents the design and application of 32-channel data collection board based on USB in the shape reconstruction system of endoscope body. The board communicate with computer through the Universal Serial Bus (USB),and utilize 12-Bit A/D Converter and 16-Channel Analog Multiplexers to collect amplified analog signals.In the experiment, the data collection board meet the functional requirement ,and can reconstruct the real-time shape of endoscope body.
