linear array
transducer (L25/10-5)
Identified by the letter L (linear) and a number (25). The number
corresponds to the radius of width of the array expressed in
millimeters. The transducer elements are electrically configured to
control the characteristics and direction of the acoustic beam. E.g, L25.
linear distance
measurement
A two-dimensional measurement in centimeters.
measurement (meas) A menu item used to start a measurement on the image.
menu items A list of menu items on the display.
microcurved
broadband array
transducer (C15/4-2)
A transducer used for abdominal and thoracic imaging. It is normally
identified by the letter C (curved) and a number (15). The number
corresponds to the radius curve of the array expressed in millimeters.
The transducer elements are electrically configured to control the
characteristics and direction of the acoustic beam.
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 5, “Safety” for a more complete description of MI.
MI/TI See Mechanical index and Thermal index.
near A system control used to adjust the amplification of shallower echoes.
See also Far and Gain.
NTSC (National
Television Standards
Committee)
A video format setting. See also PAL.
PAL (phase
alternating line)
A video format setting. See also NTSC.
patient information A menu item used to enter patient information.
power switch Turns system power on or off. The power switch is located on the front
of the system. See Figure 2 on page 10.
probe See Transducer.
review images A menu item used to review individual images stored in memory.
scanhead See Transducer.
select A command to use of the arrows on the directional controller to
highlight the desired menu item and then select it by pressing on the
middle of the directional controller.
setting A value assigned to a system parameter.
