Glossary
This glossary contains explanations of terms and abbreviations that appear in the user
guide or on the monitor. Measurements are listed in Appendix B, “Measurement and
Calculation Abbreviations”.
Term Explanation
2D Filter With 2D Filter, an automatic speckle suppression algorithm
continuously analyzes the ultrasound image for irregularities and
adjusts the smoothness to be applied. This reduces speckle and
optimizes the ultrasound image. 2D Filter supports all array
transducers (mechanical transducers are not supported).
A/B Stuart index. PS/ED.
AIUM American Institute of Ultrasound in Medicine.
ALARA As Low As Reasonably Achievable. Refers to the principle of
keeping ultrasound exposure as low as possible.
aliasing Detection of a false flow in the opposite direction from the real
flow. This can occur when the PRF used for the Doppler signal
detection is not high enough compared to the flow speed. The
problem only exists with pulsed wave Doppler detection.
Angular Compound Imaging See ACI.
array transducer A transducer that consists of a set of transducer elements, each
capable of transmitting and receiving ultrasound.
Auto (Cardiac measurement) PS, ED, RI, PS/ED
B/A ED/PS
baseline The baseline separates forward flow from reversed flow in Doppler
imaging. Moving the axis can help overcome aliasing problems.
bodymark A small drawing positioned on the image to help identify it in
documentation.
catalog A list of available items, as in a bodymark catalog or label catalog.
CFM Color flow mapping. See Color mode.
cine A function that lets you review a series of previously acquired
images.
color box When Color mode or Power mode imaging is turned on, the color
box is superimposed on the 2D image. The color box outlines the
area of the tissue in which flow information is available.
color Doppler See Color mode.
