Controlling Transducer Movement
The 2D images in the data set are scanned with the transducer in different positions.
The transducer can be moved in the following ways:
•
with a computer-controlled positioning device (external or built into the
transducer)
•
untracked freehand (see second warning on page 293)
Computer-Controlled Positioning
If the transducer is moved with a computer-controlled positioning device, you can
make measurements on the reconstructed 3D volume. There are 3 types of computer-
controlled positioning devices you can use:
•
the built-in 3D mover in the 2050 transducer
•
the pullback mover for the 1850 and 8808 transducers
•
the endocavity rotational mover (ECRM) for the 8658 biplane transducer
Anorectal Transducer 2050
The 2050 transducer has a built-in mover for 3D acquisition. For information about
setting up and attaching the 2050 transducer, see the 2050 transducer user guide.
The Pullback Mover
The pullback mover (UA0552) is designed for use with the 1850 and 8808
transducers. The mover is a computer-controlled, motor-driven probe positioner used
to move the transducer backward to produce a series of parallel images. For
information about setting it up, see the relevant transducer guide.
Figure 20-1. The pullback mover with the 1850 transducer.
Caution: The pullback mover is transducer-specific. Do not use it with other
transducers than the ones it is intended for.
