Radiography is the making of records of internal structures of the body by passage of x-
ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss
ss rays or gamma rays through the body. These records or images are typically referred
ss ss ss ss ss ss ss ss ss ss ss ss ss
ss to as radiographs.

2. Particular care must be taken when using radiation for medical imaging. This is the
ss ss ss ss ss ss ss ss ss ss s ss ss
ss result of radiation’s ability to create
ss ss ss ss ss ss s s in human tissue and possible
ss ss ss ss

a. ionizations
b. radio waves ss
c. sound waves ss
d. thermal changes ss
ANS: s s s s s s A
Some forms of electromagnetic energy, including x-rays, have the abilityto ionize atoms in
ss ss ss ss ss ss ss ss ss s s ss s
ss matter. These ionizations have the ability to disrupt the composition of matter and are
ss ss ss ss ss ss ss ss ss ss ss ss ss
ss capable of disrupting life processes. Special protection should be provided to prevent
ss ss ss ss ss ss ss ss ss ss ss

3. In the diagnosis of patient disease states, physicians can select from an array of
ss ss ss ss ss ss ss ss ss ss ss ss ss
s s medical diagnostic modalities.A few of these involve the use of ionizing energy to
ss ss s ss ss ss ss ss ss ss ss ss ss
ss create a medical image. If a physician is concerned about the use of ionizing
ss ss ss ss ss ss ss ss ss ss ss ss ss
ss radiation, he or she may choose to order any of the following diagnostic modalities
ss ss ss ss ss ss ss ss ss ss ss ss ss
ss EXCEPT
a. thermograms.
b. medical sonography. ss
c. radiography.
d. magnetic resonance imaging. ss ss
ANS: C
Radiography involves the use of x-rays for the production of medical images. Medical
ss ss ss ss ss ss ss ss ss ss ss ss
ss procedures such as thermograms, sonograms, and magnetic resonance scans use
ss ss ss ss ss ss ss ss ss
ss nonionizing energy forms and consequently do not produce ionizations in human tissue.
ss ss ss ss ss ss ss ss ss ss ss
ss They are regarded as nonionizing modalities for imaging and offer excellent alternatives
ss ss ss ss ss ss ss ss ss ss ss

The Hippocratic Corpus is writings that they emphasize rational and natural explanations
