1. A tray for positioning an object temporarily within an imaging coil comprising:
- a body having ends, sides and an object-supporting wall between the sides, the body being sized to fit within an imaging coil lower housing between lower housing sidewalls and across a lower housing surface between the sidewalls; and
at least one protrusion extending laterally outward from each side of the body to a distal edge, each protrusion further having ends and a bottom the ends being positioned and arranged to fit closely between corresponding opposed surfaces on the imaging coil and the bottom being positioned and arranged to at least partially contact a corresponding lower housing sidewall surface such that contact between the protrusions and corresponding imaging coil surfaces locates the tray at a position within the imaging coil and constrains tray movement.

Abstract
Trays for positioning of an object within an imaging coil for imaging procedures. Tray embodiments include a body having sides, ends, an object-supporting wall between the sides and at least one protrusion extending laterally outward from each side of the body. The protrusions cooperate with the structure of the particular imaging coil to locate the tray at a proper imaging position within the imaging coil. Patient-immobilization devices and object-holding devices may be associated with the trays. The trays enable off-the-shelf imaging coils to be adapted for use with an expanded number of patient-immobilization devices and object-holding devices.

19. A tray for temporarily positioning an object at a position within an imaging coil comprised of separable upper and lower housings, the tray comprising:
-
a unitary body having sides, ends and a generally concave wall between the sides, the body being sized to fit in the lower housing between lower housing sidewalls and across a generally concave lower housing surface between the sidewalls; and at least one protrusion extending laterally outward from each body side, each protrusion being integral with the unitary body and having a distal edge, opposed ends, and a bottom, the ends being positioned and arranged to fit closely between opposed imaging coil walls and the bottom being positioned and arranged to at least partially contact an upper surface of a respective lower housing sidewall to locate the tray at the position and provide constraint against tray movement.

20. A tray for temporarily positioning an object at a position within an imaging coil, the tray comprising:
-
a body having sides, ends and a generally concave wall between the sides, the body being sized to fit between lower housing sidewalls and across a generally concave lower housing surface between the sidewalls; and at least one protrusion extending laterally outward from each body side, each protrusion having a distal edge, opposed ends, and a bottom, the ends being positioned and arranged to fit closely between opposed imaging coil walls and the bottom being positioned and arranged to at least partially contact a respective lower housing sidewall to locate the tray at the position and limit tray movement.
