BME 6311 - Instrumentation and Measurement in Medicine II

Preparation: Mathematics through differential equations. Undergraduate Physics, Chemistry, Electronic Circuit Analysis. Review of basic sensor classes (resistive, piezoelectric, etc.). Principles of measurement of various biomedical parameters and effects that limit accuracy. Interfacing and loading issues. Discussion of electronic circuits for pre-amplification and signal conditioning. Noise, signal averaging, A/D conversion and sampling effects. Origin and measurement of biopotentials. Bioinstrumentation techniques used for various physiological signal monitoring methods (blood flow, ECG, respiratory, etc.). Discussion of magnetic resonance and ultrasound imaging principles and basic image quality metrics. Laboratory experiments involve construction and characterization of simple transducers and signal conditioning equipment for measuring such biomedical parameters as force, displacement, pressure, flow and biopotentials. Prerequisite: Instructor permission, and EE 203 or MAE 202.
