  2. Radiation therapy - Wikipedia

    en.wikipedia.org/wiki/Radiation_therapy

    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.

  3. Nuclear medicine - Wikipedia

    en.wikipedia.org/wiki/Nuclear_medicine

    In nuclear medicine imaging, radiopharmaceuticals are taken internally, for example, through inhalation, intravenously, or orally. Then, external detectors (gamma cameras) capture and form images from the radiation emitted by the radiopharmaceuticals. This process is unlike a diagnostic X-ray, where external radiation is passed through the body ...

  4. Medical applications of radio frequency - Wikipedia

    en.wikipedia.org/wiki/Medical_applications_of...

    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. [2]

  5. Ionizing radiation - Wikipedia

    en.wikipedia.org/wiki/Ionizing_radiation

    Radioactive isotopes for medical use, for example, are dispensed in closed handling facilities, usually gloveboxes, while nuclear reactors operate within closed systems with multiple barriers that keep the radioactive materials contained. Work rooms, hot cells and gloveboxes have slightly reduced air pressures to prevent escape of airborne ...

  6. Tomotherapy - Wikipedia

    en.wikipedia.org/wiki/Tomotherapy

    Tomotherapy is a type of radiation therapy treatment machine. [1] [2] [3] In tomotherapy a thin radiation beam is modulated as it rotates around the patient, while they are moved through the bore of the machine. The name comes from the use of a strip-shaped beam, so that only one “slice” (Greek prefix “tomo-”) of the target is exposed ...

  7. Medical physics - Wikipedia

    en.wikipedia.org/wiki/Medical_physics

    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 ...

  8. Isotopes in medicine - Wikipedia

    en.wikipedia.org/wiki/Isotopes_in_medicine

    A medical isotope is an isotope used in medicine. The first uses of isotopes in medicine were in radiopharmaceuticals , and this is still the most common use. However more recently, separated stable isotopes have come into use.

  9. Radiation - Wikipedia

    en.wikipedia.org/wiki/Radiation

    Infrared or red radiation from a common household radiator or electric heater is an example of thermal radiation, as is the heat emitted by an operating incandescent light bulb. Thermal radiation is generated when energy from the movement of charged particles within atoms is converted to electromagnetic radiation.
