Sonography Study Guide with
Complete Solutions
Ultrasound - ANS-Sound waves with frequencies above 20,000 Hz.
Infrasound - ANS-Sound range below the normal hearing range of humans less than 2
Hz
Anxiety - ANS-general state of feeling worry and fear before confronting something
emotionally / physically.
Acoustic Window - ANS-Optimal location on the body for placement of the ultrasound
transducer to demonstrate both normal anatomy and pathology.
Critical thinking skills - ANS-resourceful actions, judgments, and decisions based on the
combination of professional knowledge, experience, integrity, and ethical standards
Hippocratic Oath - ANS-a pledge observed by physicians and occasionally other
healthcare professionals containing some basic guidelines for ethical standards and
conduct between the healthcare provider and the patient
Stress - ANS-the body's typical reaction to challenging situations that are perceived as
demands on time energy or resources with.
Diagnostic ultrasound - ANS-between 2 and 15 MHz (or higher)
Radiography - ANS-the imaging specialty that utilizes x rays images to obtain images of
the body
Sonography - ANS-ultrasound imaging
Endovaginal Sonography - ANS-Technique used in gynecologic sonography in which an
ultrasound transducer is inserted into the vagina for improved visualization of pelvic
organs and structures; also referred to as transvaginal sonography
fetal echocardiography - ANS-ultrasound to analyze the fetal heart for the diagnosis of
the fetal heart defects
first trimester - ANS-Gestational weeks 1 through 12
, M Mode - ANS-motion mode that captures the movement of structures along a single
scan line represented over time, with depth along the y-axis and time along the x-axis
Pebble theory - ANS-Theory recognized by Boethius in which he hypothesized that
sound waves travel in a manner equivalent to what is observed when waves are created
by dropping a pebble into water
second trimester - ANS-gestational weeks 13 -26
vascular sonography - ANS-the medical use of ultrasound to analyze the circulatory
system
acoustics - ANS-the study of sound
Marin Mersenne - ANS-measured speed of sound in air, father of acoustics
Pythagoras - ANS-Father of Music and Harmonics; created the Sonometer
Da Vinci - ANS-Assumed that sound traveled in waves & who identified that the angle of
reflection equaled the angle of incidence.
Robert Boyle - ANS-Recognized that there must be medium through which sound can
travel
Christian Doppler - ANS-Discovered that the pitch of a sound wave varies if the source
of the sound was moving
Abbe Spallanzani - ANS-Father of Ultrasound
third trimester - ANS-29-40 weeks of Pregnancy
sound - ANS-a traveling variation in pressure and a form of energy that is produced
when a vibrating source causes molecules within a medium to move back and forth
Power Doppler - ANS-amplitude mode of Doppler where it is not the shift itself that
provides the signal but rather the strength (amplitude) of the shift
Reflectoscope - ANS-an instrument that uses ultrasound to detect flaws in metals
endoscope - ANS-a camera device inserted into the body that is used to visually
evaluate body cavities and organs
Currie Brothers (Pierre, Jacques) - ANS-created the principle of piezoelectricity
Paul Langevin & LF Richardson - ANS-Created the Hydrophone
