A medical physicist is a health professional with specialist education and training in the concepts and techniques of applying physics in medicine and competent to practice independently in one or more of the subfields (specialties) of medical physics. [1] A medical physicist plays a fundamental role in applying physics to medicine, but particularly in the diagnosis and treatment of cancer. The scientific and technological progress in medical physics has led to a variety of skills that must be integrated into the role of a medical physicist in order for them to perform their job. The "medical services" provided to patients undergoing diagnostic and therapeutic treatments must, therefore, be the result of different but complementary skills. [2] In general, the medical physicist is responsible for all scientific and technical aspects of imaging, radiation treatment, and radiation safety. It is their occupational role to ensure that medical modalities offered to patients are met with the utmost quality assurance. It is the medical physicist that manage and supervise the efforts of dosimetrists, therapists and technologists in that capacity.
The Australasian College of Physical Scientists and Engineers in Medicine (ACPSEM) is the professional body that oversees the education and certification of medical physicists in Australia and New Zealand and has a mission to advance services and professional standards in medical physics and biomedical engineering.
The presence of Medical Physicists at Expert level ('Medical Physics Experts') in healthcare in the European Union is required by the 2013/59/Euratom directive. [3] The European Federation of Organisations for Medical Physics(EFOMP) has defined a detailed inventory of learning outcomes for Medical Physics Experts in terms of Knowledge, Skills and Competences (the latter in Europe means 'responsibilities'). In Europe the professional preparation for Medical Physicists typically consists of a first degree in Physics or equivalent (e.g., biophysics, electrical or mechanical engineering, computing), a Masters in Medical Physics and a 2-year training Residency. [4] The European Commission has produced 'European Guidelines on the Medical Physics Expert'. [5]
In Finland the qualification of medical physicist is comparable to specialisation of physicians. [6] In contrast to many other countries, qualified medical physicist is considered as a post-graduate university education requiring a licentiate's degree or a PhD and a 5-year training residency. [7]
In 2013, Damascus University [8] instituted a Master's program in Medical Physics, which has significantly contributed to the training of numerous medical physicists across various university and local hospitals, as well as several universities within the Syrian Arab Republic. This program has facilitated the dissemination of knowledge through the publication of several external research articles addressing the role of medical physicists in oncology. [9] Furthermore, it has resulted in the production of multiple academic textbooks in the field of medical physics.
From October 2011 as part of the Modernising Scientific Careers scheme, the route to accreditation as a medical physicist in England and Wales is provided by the Scientist Training Programme (STP). This scheme is a three-year graduate program provided by the National School of Healthcare Science. Entrants are required to have an undergraduate degree (first or upper second class honours) in an appropriate physical science prior to this three-year graduate program.
The STP involves a part-time MSc in Medical Physics (provided by either King's College London, University of Liverpool or Newcastle University) in addition to practical training within the National Health Service. Assessment is provided by the completion of competencies and by a final assessment similar to the OSCE undertaken by other clinical staff. Completion of the STP leads to accreditation with the Institute of Physics and Engineering in Medicine (IPEM) and registration as a Clinical Scientist.
Prior to 2011 the training route in the United Kingdom was administered in two parts, and this scheme is still used in Scotland and Northern Ireland [10] ). Part I involved limited clinical experience and a full-time MSc in medical physics. Part II involved exclusively clinical experience in which the candidate would produce a portfolio of experience and submitted to the Academy for Healthcare Science which (in addition to a viva) would lead to professional accreditation with IPEM.
In North America, [11] medical physics training is offered at the master's, doctorate, post-doctorate and/or residency levels. A professional doctorate has also been recently introduced as an option. [12] Several universities in Canada and the United States offer these degrees.
As of October 2013, over 70 universities in North America have medical physics graduate programs or residencies that are accredited by The Commission on Accreditation of Medical Physics Education Programs (CAMPEP). [13] The majority of residencies are therapy, but diagnostic and nuclear have also been on the rise in the past several years.
In the United States, professional certification is obtained from the American Board of Radiology (for all 4 areas) the American Board of Medical Physics (for MRI), the American Board of Science in Nuclear Medicine (for Nuc Med and PET). As of 2012, enrollment in a CAMPEP-accredited residency or graduate program is required to start the ABR certification process. As of 2013, completion of a CAMPEP-accredited residency is required to advance to part 2 of the ABR certification process. [14]
In Canada, professional certification is obtained from the Canadian College of Physicists in Medicine (for all 4 areas and Mammography). Since 2016, eligibility requirements for Radiation Oncology Physics certification includes graduation and post-graduate training from a CAMPEP accredited institution. [15]
The Association of Medical Physicists in Russia is organized and operates . Teaching of medical physics is carried out at Moscow State University, [16] Moscow Institute of Physics and Technology , Kuban State University. [17] The scientific journal "Medical Physics" is published .
There are regular regional and international educational medical physics activities. The oldest of these is the International College on Medical Physics at the International Centre for Theoretical Physics (ICTP), Trieste, Italy. This College has educated more than 1000 medical physicists from developing countries.
Biomedical engineering (BME) or medical engineering is the application of engineering principles and design concepts to medicine and biology for healthcare applications. BME is also traditionally logical sciences to advance health care treatment, including diagnosis, monitoring, and therapy. Also included under the scope of a biomedical engineer is the management of current medical equipment in hospitals while adhering to relevant industry standards. This involves procurement, routine testing, preventive maintenance, and making equipment recommendations, a role also known as a Biomedical Equipment Technician (BMET) or as a clinical engineer.
Radiology is the medical specialty that uses medical imaging to diagnose diseases and guide their treatment, within the bodies of humans and other animals. It began with radiography, but today it includes all imaging modalities, including those that use no ionizing electromagnetic radiation, as well as others that do, such as computed tomography (CT), fluoroscopy, and nuclear medicine including positron emission tomography (PET). Interventional radiology is the performance of usually minimally invasive medical procedures with the guidance of imaging technologies such as those mentioned above.
Medical physics deals with the application of the concepts and methods of physics to the prevention, diagnosis and treatment of human diseases with a specific goal of improving human health and well-being. Since 2008, medical physics has been included as a health profession according to International Standard Classification of Occupation of the International Labour Organization.
A radiation oncologist is a specialist physician who uses ionizing radiation in the treatment of cancer. Radiation oncology is one of the three primary specialties, the other two being surgical and medical oncology, involved in the treatment of cancer. Radiation can be given as a curative modality, either alone or in combination with surgery and/or chemotherapy. It may also be used palliatively, to relieve symptoms in patients with incurable cancers. A radiation oncologist may also use radiation to treat some benign diseases, including benign tumors. In some countries, radiotherapy and chemotherapy are controlled by a single oncologist who is a "clinical oncologist". Radiation oncologists work closely with other physicians such as surgical oncologists, interventional radiologists, internal medicine subspecialists, and medical oncologists, as well as medical physicists and technicians as part of the multi-disciplinary cancer team. Radiation oncologists undergo four years of oncology-specific training whereas oncologists who deliver chemotherapy have two years of additional training in cancer care during fellowship after internal medicine residency in the United States.
A radiation therapist, therapeutic radiographer or radiotherapist is an allied health professional who works in the field of radiation oncology. Radiation therapists plan and administer radiation treatments to cancer patients in most Western countries including the United Kingdom, Australia, most European countries, and Canada, where the minimum education requirement is often a baccalaureate degree or postgraduate degrees in radiation therapy. Radiation therapists can also prescribe medications and radiation, interpret tests results, perform follow ups, reviews, and provide consultations to cancer patients in the United Kingdom and Ontario, Canada . In the United States, radiation therapists have a lower educational requirement and often require postgraduate education and certification in order to plan treatments.
A Doctor of Medicine is a medical degree, the meaning of which varies between different jurisdictions. In the United States, and some other countries, the M.D. denotes a professional degree. This generally arose because many in 18th-century medical professions trained in Scotland, which used the M.D. degree nomenclature. In England, however, Bachelor of Medicine, Bachelor of Surgery (M.B.B.S.) was used: in the 19th century, it became the standard in Scotland too. Thus, in the United Kingdom, Ireland and other countries, the M.D. is a research doctorate, honorary doctorate or applied clinical degree restricted to those who already hold a professional degree (Bachelor's/Master's/Doctoral) in medicine. In those countries, the equivalent professional degree to the North American, and some others' usage of M.D. is still typically titled Bachelor of Medicine, Bachelor of Surgery.
A Medical Laboratory Scientist (MLS) or Clinical Laboratory Scientist (CLS) or Medical Technologist (MT) is a licensed Healthcare professional who performs diagnostic testing of body fluids, blood and other body tissue. The Medical Technologist is tasked with releasing the patient results to aid in further treatment. The scope of a medical laboratory scientist's work begins with the receipt of patient or client specimens and finishes with the delivery of test results to physicians and other healthcare providers. The utility of clinical diagnostic testing relies squarely on the validity of test methodology. To this end, much of the work done by medical laboratory scientists involves ensuring specimen quality, interpreting test results, data-logging, testing control products, performing calibration, maintenance, validation, and troubleshooting of instrumentation as well as performing statistical analyses to verify the accuracy and repeatability of testing. Medical laboratory scientists may also assist healthcare providers with test selection and specimen collection and are responsible for prompt verbal delivery of critical lab results. Medical Laboratory Scientists in healthcare settings also play an important role in clinical diagnosis. An estimated 70% of medical decisions are based on laboratory test results and MLS contributions affect 95% of a health system's costs.
Clinical engineering is a specialty within biomedical engineering responsible for using medical technology to optimize healthcare delivery.
PGY, short for postgraduate year, is a North American numerical construct denoting the progress of postgraduate medical, dental, veterinary, podiatry or pharmacy residents in their residency programs. It is used to stratify responsibility in most training programs and to determine salary. The grade of a resident or fellow is denoted with an Arabic or Roman numeral after the PGY designation, such as PGY-3 for a third-year resident in any specialty.
Radiographers, also known as radiologic technologists, diagnostic radiographers and medical radiation technologists are healthcare professionals who specialise in the imaging of human anatomy for the diagnosis and treatment of pathology. Radiographers are infrequently, and almost always erroneously, known as x-ray technicians. In countries that use the title radiologic technologist they are often informally referred to as techs in the clinical environment; this phrase has emerged in popular culture such as television programmes. The term radiographer can also refer to a therapeutic radiographer, also known as a radiation therapist.
The Institute of Physics and Engineering in Medicine (IPEM) is the United Kingdom's professional body and learned society for physicists, engineers and technologists within the field of medicine, founded in 1995, changing its name from the Institution of Physics and Engineering in Medicine and Biology (IPEMB) in 1997. The Institute is governed by an elected Board of Trustees reporting to which are the Science, Research and Innovation Council and the Professional and Standards Council. The councils have operational responsibility for scientific and professional aspects of the Institute's work, respectively. Beneath the councils is a substructure of committees, groups and panels of members, which undertake the work of the Institute.

The European Federation of Organisations for Medical Physics (EFOMP) was founded in May 1980 in London to serve as an umbrella organisation representing the national Medical Physics societies in Europe. The office moved to Utrecht in January 2021. It is a non-profit organisation and aims to foster and coordinate the activities of its national member organisations, encourage exchange and dissemination of professional and scientific information, develop guidelines for education, training and accreditation programmes and to make recommendations on the responsibilities, organisational relationships and roles of medical physicists.
A clinical technologist, also known as a healthcare science practitioner, is a medical professional involved in the practical delivery of medical physics and clinical engineering services. In some locations there is considerable overlap in closely related terms, for example in many countries technologist and radiographer are synonyms, while in the United Kingdom they are considered separate professions. Clinical technologists can be found in nuclear medicine, radiotherapy, radiation protection, and rehabilitation engineering departments, and they are often described by their scope of practice.
