Evaluating the Phantom

Remember

A 4.5 MHz probe will provide a good overall view of the phantom for this demonstration.
1.
Turn the handle out of the way and slide the cover off the phantom.
2.
To couple with water, fill the dam with distilled water. For a better image quality,
use gel.
3.
Rest the transducer on the scanning surface. Adjust the scanner to display the
full depth of the phantom.
You may notice that the tissue echoes near the bottom of the phantom fade into noise.
The depth at which usable echoes disappear is called the depth of penetration. The
depth markers on the phantom label will help you determine the depths of the targets.
The phantom comes ready to scan. Do not peel off the
surface material.
Never press the transducer into the scanning surface.
Always clean and dry the scanning surface after each use.
Never leave coupling gel or water on the scanning surface
for more than a few hours.
Do not use mineral oil, baby oil, or lanolin-based gels as a
coupling medium.
