Glossary
Terms
For ultrasound terms not included in this glossary, refer to Recommended Ultrasound Terminology, Third
Edition, published in 2011 by the American Institute of Ultrasound in Medicine (AIUM).
as low as reasonably
achievable (ALARA) The guiding principle of ultrasound use, which states that you should keep
patient exposure to ultrasound energy as low as reasonably achievable for
diagnostic results.
curved array
transducer Identified by the letter C (curved or curvilinear) and a number (60). The
number corresponds to the radius of curvature of the array expressed in
millimeters. The transducer elements are electrically configured to control
the characteristics and direction of the acoustic beam. For example, C60xp.
depth Refers to the depth of the display. A constant speed of sound of
1538.5 meters/second is assumed in the calculation of echo position in the
image.
in situ In the natural or original position.
linear array transducer Identified by the letter L (linear) and a number (38). The number
corresponds to the length of the array expressed in millimeters. The
transducer elements are electrically configured to control the characteristics
and direction of the acoustic beam. For example, L38x
i p .
mechanical index (MI) An indication of the likelihood of mechanical bioeffects occurring: the higher
the MI, the greater the likelihood of mechanical bioeffects. See
Chapter 10,
“Acoustic output,” for a more complete description of MI.
MI/TI Refer to mechanical index (MI) and thermal index (TI) .
phased array
transducer A transducer designed primarily for cardiac scanning. Forms a sector image
by electronically steering the beam direction and focus. For example, P21xp.
skinline A depth on the display that corresponds to the skin/transducer interface.
SonoMB technology A subset of the 2D imaging mode in which the 2D image is enhanced by
looking at a target from multiple angles and then merging or averaging the
scanned data together to improve overall image quality and, in parallel,
reducing noise and artifacts.
Tissue Doppler
Imaging (TDI) A pulsed wave Doppler technique used to detect myocardial motion.
