Content (Syllabus outline)

Physics of the living matter: an introduction to medical physics (bioelements, homeostasis, feedback loops in living matter), basics of biochemistry (chemical bonding, hydrogen bonding, water molecule, isomerism, biomolecules, proteins, DNA, lipids), basic physiology concepts (membrane, ions, membrane potential), action potential of nerve cells (morphology of the action potential, Hodgkin-Huxley model of the membrane), cardiac muscle fiber (action potential, current dipole), heart muscle (syncytium). Imaging methods in medical physics: electrocardiogram, electroencephalogram, x-ray (ionizing radiation, sources of X-rays, X-rays interaction with living matter, examples of X-ray images), the basic principles of X-ray tomography, fundamentals of dosimetry (interaction of ionizing radiation with living tissues, dose, protection against radiation), magnetic resonance imaging (physical basis, excitation and relaxation of nuclei, sequences, basic elements of imaging, use of gradients, k-space), ultrasonic imaging (physical basis, acoustic impedance, attenuation, warp imaging, Doppler imaging), imaging in nuclear medicine (concept of radiopharmaceutical, gamma radiation sources, an overview of tomographic methods - SPECT, PET, security imaging). Safety at work, which include the patient (the part that is connected to the medical physics)
