The Nuclear Imaging head is a System 600XR manufactured by
The system has 91 photomultiplier tubes with a crystal size
of 388mm X 508mm.
The computer system is Starcam 4000 by GE.
The collimator is high resolution.
The gantry that supports and moves the head was manufactured
by Motion Control Systems of Redmond, WA.
The installation is primarily used to scan horses which are
secured into a platform/paddock located in front of the
unit. A handheld pendant is used to control 5 degrees of
motion. The tower bridge can move forward & back. The tower
moves left & right along the bridge. The carriage can be
raised and lowered via the ball screw which spans the
vertical length of the unit. The fork which suspends the
700 lb detector head rotates clockwise and counter clockwise
and the head tilts forward and back within the fork itself. The bridge that the tower sits on straddles a pit, allowing
the scanner to be lowered and moved under the belly of the
patient (see last picture).
"The installation was made very difficult because the
contractors installed the dropped ceiling superstructure in
the examination lab before we got the tower installed. That
resulted in having to stand the 3000 lb, 14 ft. tower up onto
the moving bridge that straddled a 4 ft deep pit in a very
limited space. There was less then 5 feet of open space on
each side of the pit. Because of the dropped ceiling
structure, there was only 5 feet of high ceiling space
available in front of the pit. We used 2 forklifts working
in tandem to lift the unit in place, working under portable
lighting. It was a difficult installation - at one point we
actually had to stack bricks up in the corner of the pit so
the forklift could drive over without falling in. I came
within a skinned knuckle of taking a cutting torch to the
dropped ceiling structure."
