Tematika

The use of measuring instruments is indispensable in both medical diagnostics and research. Based on the physical nature of the measured parameter (voltage, pressure, flow, temperature, optical), we discuss the operating principle of each device, covering the electronic background of processing on both the hardware and software sides. The correct interpretation of the results provided by everyday instruments, the recognition of their errors, and their elimination may become easier after mastering the approach given by the course.
