The science or study of radiation used in medicine; a branch of medical science that deals with the therapeutic use of x-rays, radioactive substances, and other forms of radiant energy.

RADIOLOGY (roentgenology)

12

An image or picture produced on a receptor (radiation-sensitive film, digital sensor) by exposure to ionizing radiation; a two-dimensional representation of a three-dimensional object.

RADIOGRAPH
