The vertical and horizontal rows of monofilament targets are scanned from all three (large)
scanning surfaces. When viewed from three different distances, they help distinguish between
horizontal and angular scale errors, depending on whether the scale errors are similar or different.
2.3 Optional Scanning Trough (84-318)
This shallow tray has a soft plastic bottom. It is used with scanning transducers designed for water-
immersion use or for rounded transducers that make poor contact with the phantom scanning surface.
Procedure
Cover the trough's bottom surface with a generous amount of scanning gel. Place the trough on the
desired scanning surface, making contact first at one end and laying it down carefully. Avoid air bubbles
in the space between the trough and the phantom surface. With the fingers, squeeze out the air bubbles
and as much of the gel as possible. Fill the trough with scanning oil or water, and position the phantom so
the trough is uppermost and horizontal.
2.4 Storage
The Multipurpose Tissue/Cyst Phantoms from Nuclear Associates should be stored at room temperature.
Damage may occur if the phantoms are subjected
to temperatures below 32°F or above 150°F (0° -
66°C).
For transport outside of this range, the optional Insulated Carrying/Storage Case 89-317 is
recommended.
To minimize dessication of the filling gel, the phantom may be stored in a closed cabinet or case in which
there is a jar or bowl filled with water. The high humidity will reduce dessication to a minimum.
