Receiver Controls; Acoustic Artifacts; Guidelines For Reducing Mi And Ti - FujiFilm SonoSite M-Turbo User Manual

Receiver controls

The receiver controls are the gain controls. Receiver controls do not affect output. They should
be used, if possible, to improve image quality before using controls that directly or indirectly
affect output.

Acoustic artifacts

An acoustic artifact is information, present or absent in an image, that does not properly
indicate the structure or flow being imaged. There are helpful artifacts that aid in diagnosis and
those that hinder proper interpretation. Examples of artifacts include:
• Shadowing
• Through transmission
• Aliasing
• Reverberations
• Comet tails
For more information on detecting and interpreting acoustic artifacts, see the following

Guidelines for reducing MI and TI

The following are general guidelines for reducing MI or TI. If multiple parameters are given,
the best results may be achieved by minimizing these parameters simultaneously. In some
modes changing these parameters does not affect MI or TI. Changes to other parameters may
also result in MI and TI reductions. Please note the MI and TI values on the right side of the
screen.
