MULTIPLE CHOICE x@




1. The use of x-rays to create a medical image on patients is referred to as
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@


a. electrocardiography.
b. radiography.
c. sonography.
d. magnetic resonance imaging. x@ x@




ANS: B x@x@


Radiography is the making of records of internal structures of the body by passage of
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x


@x-
rays or gamma rays through the body. These records or images are typically referred
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x


@to as radiographs.

c. sound waves x@


d. thermal changes x@




ANS: A x@x@


Some forms of electromagnetic energy, including x-
x@ x@ x@ x@ x@ x@


rays, have the ability to ionize atoms in matter. These ionizations have the ability to
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@


disrupt the composition of matter and are capable of disrupting life processes. Specia
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@
