Physics concepts and procedures in the prevention, diagnosis, and treatment of disease


Journal of Medical Physics and Applied Sciences aim is to publish the work and reports on maintaining and improving the quality, safety and cost-effectiveness of healthcare services through patient-oriented activities requiring expert action, involvement or advice regarding the specification, selection, acceptance testing, commissioning, quality assurance/control and optimised clinical use of medical devices and regarding patient risks and protection from associated physical agents (e.g. x-rays, electromagnetic fields, laser light, radionuclides) including the prevention of unintended or accidental exposures.

Medical physics is also called biomedical physics, medical biophysics, applied physics in medicine, physics applications in medical science, radiological physics or hospital radio-physics which is, in general, the application of physics concepts, theories, and methods to medicine or healthcare. Medical physics departments may be found in hospitals or universities.  The biomedical physics seeks to understand the role of physical processes occurring on molecular, cellular, or macroscopic scales; in vital biological functions, ranging from the interaction of chemicals with DNA, to the extraction of oxygen from red blood cells, to the generation of complex electrical signals in the brain and nervous system; and physical principles of medical devices.

Medical Physics is the application of physics to medicine. It uses physics concepts and procedures in the prevention, diagnosis, and treatment of disease.  Medical Physics fulfils an important role in medicine, in biological and medical research, and in the optimisation of certain health related activities. Medical Physics includes areas such as Radiotherapy physics, Diagnostic Radiology physics, Nuclear Medicine Physics, and Radiation Protection.  Diagnostic Radiology and Nuclear Medicine are often grouped in what is termed as “Diagnostic Imaging”, although there are therapeutic aspects of Nuclear Medicine associated with Radiation Therapy.  Other areas of interest in Medical Physics include the measurement of ionising radiation, magnetic resonance imaging, and the application of lasers, ultrasound, and other technologies which utilise physics concepts as applied to medicine.  The scope of duties of medical physicists covers a wide array of activities in modern hospitals where radiation technology is used. As part of a team of health professionals, medical physicists play a central role in assuring the safe and effective use of radiation in medicine.  These goals of quality are achieved through the use of QA/QC protocols in the context of radiation-related technologies, radiation therapy dose planning and verification, diagnostic image optimization and dose reduction, and data management and analysis, all of which are based on an in depth understanding of radiation physics principles and radiation technology. The information presented here is aimed at providing the practicing medical physicist with a resource of practical material, as well as guidance for working in clinical situations. Furthermore, some of the materials are very useful in the support of teaching programs.
