The manual entitled "Medical Biophysics Practices" has been written for first year students of medicine, dentistry and pharmacy. These practices are in strong connection with the topics of the lecture of medical physics, and the majority of them are measurements performed by the students individually or in pairs. This manual contains a short review of these measurements, and a summary of the related theoretical background. For a successful work in the laboratory, it is also essential to read the paragraphs of the textbook listed before the description of the measurements.
