Medical applications of radio frequency (RF) energy, in the form of electromagnetic waves (radio waves) or electrical currents, have existed for over 125 years, [1] and now include diathermy, hyperthermy treatment of cancer, electrosurgery scalpels used to cut and cauterize in operations, and radiofrequency ablation.

Nuclear medicine (nuclear radiology, nucleology), [1] [2] is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease. Nuclear imaging is, in a sense, radiology done inside out , because it records radiation emitted from within the body rather than radiation that is transmitted through ...
MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from computed tomography (CT) and positron emission tomography (PET) scans. MRI is a medical application of nuclear magnetic resonance (NMR) which can also be used for imaging in other NMR applications, such as NMR spectroscopy. [1]
"Radiation therapy" defined as the utilization of electromagnetic or particle radiation in medical therapy has 3 main branches, including external beam radiation therapy (teletherapy), locoregional ablative therapy (such as brachytherapy (sealed source radiation therapy), selective internal radiotherapy (SIRT), radiofrequency ablation ...
Laser radiation being delivered via a fiber for photodynamic therapy to treat cancer. A 40-watt CO 2 laser with applications in ENT, gynecology, dermatology, oral surgery, and podiatry Laser medicine is the use of lasers in medical diagnosis , treatments, or therapies, such as laser photodynamic therapy , [ 1 ] photorejuvenation , and laser ...
Traditionally, medical physicists are found in the following healthcare specialties: radiation oncology (also known as radiotherapy or radiation therapy), diagnostic and interventional radiology (also known as medical imaging), nuclear medicine, and radiation protection. Medical physics of radiation therapy can involve work such as dosimetry ...
The medical applications of nuclear technology are divided into diagnostics and radiation treatment. Imaging - The largest use of ionizing radiation in medicine is in medical radiography to make images of the inside of the human body using x-rays. This is the largest artificial source of radiation exposure for humans.
Radiation oncology is the medical specialty concerned with prescribing radiation, and is distinct from radiology, the use of radiation in medical imaging and diagnosis. Radiation may be prescribed by a radiation oncologist with intent to cure or for adjuvant therapy.
