Course detail
Medical diagnostic devices
FEKT-BPC-LDTAcad. year: 2023/2024
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.
