energy carried by waves or streams of particles

radiation

2

high-energy radiation produced by the collision of a beam of electrons with a metal target in an X-ray tube

X-radiation

3

a beam of energy that has the power to penetrate substances and record image shadows on photographic film

X-ray

4

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

radiology

5

11

what is the importance of radiographs

to identify many conditions that may otherwise go undetected and to see conditions that cannot be identified clinically

12

name some uses of radiographs

detect lesions
confirm/classify disease
localized lesions or foreign objects
eval. growth and development
document condition of a patient
