Course detail

Medical Diagnostic Technology

FEKT-ALDTAcad. year: 2013/2014

The topics in this course cover operating principles and construction of diagnostic devices and systems for recording of electrical biosignals and non-electric characteristics from human body (ECG,EEG,EMG, EGG, impedance measurements, recording of blood pressure, measurement of blood flow, pletysmography, temperature measurment). The LabView programming environment is used for practicle experiences with acquisition and processing of different biosignal. The Vernier sensors and acquisition cards are used for this purpose as well.

- describe and explain principles of instrumentations for ECG, EEG and EMG sensing,
- describe and explain methods and devices for non-invasive and invasive blood pressure measurement,
- list methods for blood flow measurement,
- explain dilution method for blood flow measurement,
- apply Doppler principle for blood flow measurement,
- define principle of methods in pletysmography,
- discuss and define source of errors in selected diagnostic approaches,
- explain term "vital function monitoring"

Prerequisites

Student should be able to describe basic pasive electronic components (resistance, inductance, capacitance) and should have knowledge about basic physical laws and properties of physical fields obtained in Physics I and II.
