Medical Diagnostic Technology
FEKT-ALDTAcad. year: 2018/2019
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.
Learning outcomes of the course unit
Student will obtain knowledge about principles and properties of selected medical instrumentation used for diagnosis. Student will be able to apply this knowledge during data/signal interpretation or during specification and selection process of medical instruments. The student is able to:
- describe principles of bio-amplifiers,
- list and dicussed their properties,
- 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"
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.

Planned learning activities and teaching methods
Techning methods include lectures and practical laboratories. Course is taking advantage of e-learning (Moodle) system. Students have to write three assignment during the course.
Assesment methods and criteria linked to learning outcomes
Laboratory work - 0 - 20 points.
Test - 0 - 30 points.
Written exam - 0 - 50 points.
The test is oriented to basic terminology.
The written exam verify knowledge in principle of medical instrumentation.
