EVM 101 CERTIFICATION EVALUATION
TESTED QUESTIONS WITH COMPLETE
SOLUTION PACKAGE
●● TGC'S
Answer: Time Gain Compensation is used to enhance specific areas of
interest by increasing or decreasing the amplification of echoes at
different depths. It compensates for losses in signal strength as the
ultrasound passes anatomical structures.
●● Focus aka Focal/Trans Zone
Answer: to improve resolution and clarity, transducers are focused.
Enhances the resolution and clarity of specific anatomical structures.
●● 2D Gain
Answer: gain control changes the gain of the image by increasing or
decreasing the overall amplification of the received echoes and
brightness of the image.
●● Near field
Answer: on ultrasound the image area closest to the transducer and the
more superficial part of your neck or body.
,●● Far field
Answer: on ultrasound the image area further away from the transducer
and the deeper part of your neck or body.
●● Screen Orientation Indicator
Answer: ultrasound transducers have a mark that corresponds to the
mark on the ultrasound machines screen. The mark on the transducer is
known as the index.
●● Hyperechoic
Answer: producing echoes of higher amplitude than the surround
medium brighter.
●● Hypoechoic
Answer: producing echoes of lower amplitude than normal for the
surrounding medium. Less bright.
●● Heterogenous
Answer: Different textures & compositions
●● Anechoic
Answer: describes property of being without echoes (black) appearance
on a sonographic image.
, ●● Echogenic
Answer: the ability to create an ultrasound echo.
●● Frequency
Answer: measure of how often something "vibrates" per second.
●● Mega
Answer: Million
●● Transverse
Answer: divides the body cross sectionally into top and bottom (superior
and inferior) sections
●● Longitudinal (sagital)
Answer: divides body into right and left sections
●● When does scatter occur?
Answer: scatter occurs when ultrasound waves encounter a medium with
a non-homogenous surface.
●● Modes of Vascular Ultrasound
Answer: B-Mode, 2D Mode, Color Doppler, Spectral Doppler
