Intro to Sonography Questions with Verified
Correct Answers
diagnostic medical sonography, ultrasound, echosonography, and ultrasonography
what are four terms used to describe the use of high-frequency sounds waves in medical
imaging?
ultrasound
_______: refers to sound that is well above the human range of hearing that is used in
medicine to diagnose and assess healthy and abnormal structures, vessels, or organs inside
the body.
sonography
in diagnostic imaging, _______ is the preferred term to describe the use of sound in the range
of 1 to 20 MHz or greater for patient imaging.
transducer
sonography equipment creates waves of energy when an electrical voltage is applied to the
ceramic element housed inside the _______
receiver
the transducer acts as a _______ that processes the echoes returning from inside the body.
composite
the received echoes within the body create a ______ image that is displayed in real time on a
monitor to be viewed, saved, and stored.
greater
, lower frequency transducers permit ______ penetration for imaging organs such as the liver.
sharper
higher frequency transducers allow a ______ image for superficial structures such as breast
tissue.
general, echocardiography, and vascular
diagnostic sonography has what three major imaging specialty areas?
obstetrics and pediatrics
sonography is a preferred modality for imaging in _______ and ________ b/c it can be
performed quickly and effectively to obtain a diagnosis and does not use ionizing radiation.
military
medical applications for imaging emerged from the _______
sound navigation and ranging
during WWI, detection of submarines underwater using high frequency sound was developed
and termed _____ _____ and ______ (SONAR)
a-mode or amplitude mode
the first ______ ultrasound unit was built in the early 1950s. It displayed the intensity of blips
on a screen to determine what anatomic structures were being imaged from the returning echo
information that came back deep within the body
brigtness mode ,patient-mode
the growth of ultrasound continued in the 1960s and equipment matured with _____ mode.
_______ mode displayed a series of dots on a screen that represented varying shades of gray
