As low as reasonably achievable. 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.
Ultrasound transmission gel. Widely used gel for
diagnostic and therapeutic medical ultrasound.
Acoustically correct for a broad range of frequencies used,
is completely aqueous, formaldehyde and spermicide
free. Produced by Parker Laboratories, Inc.
In the natural or original position.
A device that transforms one form of energy into another
form of energy. Ultrasound transducers contain
piezoelectric elements, which when excited electrically,
emit acoustic energy. When the acoustic energy is
transmitted into the body, it travels until it encounters an
interface, or change in tissue properties. At the interface,
an echo is formed that returns to the transducer, where
this acoustic energy is transformed into electrical energy,
processed, and displayed as anatomical information.
Real-time image technology that reduces speckle noise
and artifacts in high-resolution images while preserving
and enhancing critical tissue information.
