Part I. Equilibrium and the action potential of cell-The physical size of importance for diagnosis in medicine (ionizing radiation are not included) electrodes to measure the electrophysiological signals - Biological signals (amplifiers, analog methods onedimensional biomedical signal processing, instruments for recording the signal) - Pressure in the medical measurements; electromyography, electroneurography, electrocardiography and electroencephalography;-MRI-ultrasound (diagnosis, therapy, ultrasound tomography, cardiosonography) - Measurement of pressure and flow of gases and liquids in the body, - measuring substances in blood and gases (spectrophotometry, flame photometry) in the medical-laser measurements and therapy. Thermography, Electrical Simulation (pacemaker, rehabilitation movement). Part II – Medical devices: Radiological Diagnosis (X-ray, mammography, CT, Osteodenzitometar, DICOM standard); Nuclear medicine (gamma, SPECT, PET);-radiotherapy: radiotherapy devices (teletherapeutic, linear accelerator, Proton cyclotron, X-ray); planning radiotherapy-Monte Carlo techniques in medical - criteria: measurement and detection of ionizing radiation, types of detectors (TLD, scintilation counters, solid counters, GM counters, ionization chambers, neutron radiation detectors, radiation detectors energy protons)-Q in the radiological diagnosis and radiotherapy.
