electrical voltage is applied to the ceramic element housed inside the _______
receiver - Correct Answer✔️✔️-the transducer acts as a _______ that processes the echoes
returning from inside the body.
composite - Correct Answer✔️✔️-the received echoes within the body create a ______ image that

, greater - Correct Answer✔️✔️-lower frequency transducers permit ______ penetration for
imaging organs such as the liver.
sharper - Correct Answer✔️✔️-higher frequency transducers allow a ______ image for superficial
structures such as breast tissue.
general, echocardiography, and vascular - Correct Answer✔️✔️-diagnostic sonography has what
three major imaging specialty areas?
obstetrics and pediatrics - Correct Answer✔️✔️-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 - Correct Answer✔️✔️-medical applications for imaging emerged from the _______
sound navigation and ranging - Correct Answer✔️✔️-during WWI, detection of submarines
underwater using high frequency sound was developed and termed _____ _____ and ______
(SONAR)
a-mode or amplitude mode - Correct Answer✔️✔️-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 - Correct Answer✔️✔️-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 or "gray scale". These dots determined whether a
structure inside the patient was solid such as the liver or fluid-filled such as the bladder.
