Table 5-1 B-mode Touch Screen Controls
FOV
The Field of View control adjusts the image width. Full,
Large, Med. and Small settings are available. As the image
becomes narrower, the frame rate increases.
Steer
The Steer control is only available for linear transducers and
steers the B-mode image left or right, without moving the
transducer. This function can be particularly useful when
visualizing needles or other objects that are enhanced by a
perpendicular beam. Steer is not available if Spatial
Compounding or Trapezoid are turned on.
Trapezoid
The Trapezoid control activates the trapezoidal imaging on
linear transducers. It is a part of the B-mode function and
available in live imaging.
Image Type
B-mode supports presets for Detail, General, and
Penetration. See section 10.3.2 for more information.
Line Density
Adjusts the line density to optimize the lateral resolution for
the best possible image. The higher the line density, the
higher the lateral resolution, but the lower the frame rate.
Needle
Press to invoke the touch screen for Needle Enhancement
Visualization and Needle Biopsy Guide functions. See
section 6.4 and 6.5 for more information.
Acoustic power
Adjusts the acoustic output power of the activate transducer
and is only available in live imaging. Higher acoustic power
numbers correspond to increased sensitivity in the image
with improved penetration, but the ALARA principle should
be followed in actual clinical situations.
Center Line
Press to activate the Center Line function. Refer to section
6.6 for details.
