Aorta

A radiographic process in which the aorta and it's branches are injected with any of various contract media for visualization

Axial

pertaining to or situated on the axis of a structure or part of the body

Betatron

A cyclic accelerator that produces high energy electrons for radiotherapy treatments

Brachytherapy

The placement of radioactive sources in contact with or implanted into the tissues to be treated

Bronchography

An x ray examination of the interior passageways of the lower respiratory tract (larynx trachea and bronchi) following the coating of these structures with a radiopaque substance

Breakdown word

Cineradiography

The filming with a movie camera of the images that appear on a fluorescent screen especially those images of the body structures that have been injected with a nontoxic radiopaque medium diagnostic purposes.

Computed tomography

An x ray technique that produces a film representing a detailed cross section of tissue structure

Digital radiography

Any method of x image formation that uses a computer to store and manipulate data

Doppler effect

The apparent change in frequency of sound or light waves emitted by a source as it moves away from or toward an observer

Eversion

A turning outward or inside out such as a turning of the foot outward at the ankle

Fluorescence

The emission of light of one wavelength (usually ultraviolet) when exposed to light of a different (usually shorter) wavelength

Fluoroscopy

A technique in radiology for visually examining a part if the body or the function of an organ using fluoroscope

Gamma camera

A device that uses the emission of the light from a crystal by gamma rays to produce an image of the distribution of radioactive material in a body organ

Gamma rays

An electromagnetic radiation of short wavelength emitted by the nucleus of an atom during a nuclear reaction. Also called gamma radiation

Half life

The time required for a radioactive substance to lose 50% of it's activity through decay

Interstitial therapy

Radiotherapy in which needles or wires that contain radioactive material implanted directly into tumor areas

Inversion

An abnormal condition in which an organ is turned inside out such as uterine inversion also refers to turning inward

Ionization

The process in which a neutral atom or molecule gains or loses electrons and thus acquires a negative or positive electric charge

Irradiation

Exposure to any form of radiant energy such as heat light or x ray

Lethal

Capable of causing death

Linear accelerator

An apparatus for accelerating charged subatomic particles used in radiotherapy, physics research, and production of radionuclides

MRI

Medical imaging that uses radio frequency signals as it's source of energy

Nuclear medicine

A medical discipline that uses radioactive isotopes in the diagnosis and treatment of disease

Orthovoltage

The voltage range of 100 KeV to 350 KeV supplied by some x ray generators used for radiation therapy

Piezoelectric

The generation of a voltage across a solid when a mechanical stress is applied

Positron emission tomography

A computerized radiographic technique that employs radioactive substances to examine the metabolic activity of various body structures

Pyelography

A technique in radiology for examining the structures and evaluating the function of the urinary system

Rad

Abbreviation for radiation absorbed dose. The basic unit of absorbed dose of ionizing radiation

Radiation therapy

The treatment of neoplastic disease by using x rays or gamma rays usually from Cobalt source to deter the growth of malignant cells by decreasing the rate of cell division or impairing DNA synthesis.

Radioactivity

The ability of a substance to emit rays or particles (alpha beta or gamma) from it's nucleus

Radiographer

An allied health professional trained to use x ray machines and other imaging

Radiommunoassay

An technique in radiology used to determine the concentration of an antigen antibody or other protein in the serum

Radioisotope

A radioactive isotope (of an element) used for therapeutic and diagnostic purposes

Radiolucent

Pertaining to material that allow x rays to penetrate with minimum absorption

Radionuclide (radioisotope)

An isotope or nuclide that undergoes radioactive decay

Radiopaque

Not permitting the passage of X Rays or other radiant energy
