The next subsections discuss positioning the Camera Head with the different MRI mounts. You
may consult the section for your particular mount, and then continue to Section 7.9.2 to
mount the Camera Head and Illuminator onto the Mounting Bar, and the Mounting Bar onto
the mount.

7.9.1.1
Tray Mount (Siemens Full Body Scanners)
The Tray Mount was designed to be inserted into the end of the bore and to be held in place
against the bedrails using nylon bolts at the bottom of the mount. The mount, pictured in the
left side of Figure 7-11 and throughout Figure 7-12, has a post which holds the Mounting Bar
on an adjustable ball head. The post is attached to the tray's bottom using four nylon bolts and
can be flexibly positioned at multiple viewing points in the center of the tray (bottom images of
Figure 7-12), or off to one side or the other (left and top-middle images of Figure 7-12) for
difficult tracking environments. Similarly, the height at which the Mounting Bar is positioned
can be adjusted, and two different length posts are included for added flexibility in the range of
heights at which the Mounting Bar can be positioned.
The Tray Mount has an optional high quality projection screen that is attached at the end of
the tray using bolts. It also comes in a configuration to hold a screen supplied by the user
(bottom images of Figure 7-12). For larger bore openings there is a rectangular riser block that
raises the screen higher by a couple of centimeters. If this is too high for your bore then remove
this riser block (see top right image of Figure 7-12). There are two different lengths of bolts for
use with or without the riser block.
The Tray Mount slides into the end of the bore where its feet rest on the bedrails. Four nylon
bolts attached to the feet should be turned to put pressure on the bedrails and wedge the
mount securely into place. Although the Tray Mount was designed to be operated from the end
of the bore, it is possible to slide it deeper into the bore in the direction of the head coil. Deeper
positioning will work fine and not introduce problems for MRI imaging, however eddy currents
