Abstract: A sterilizer for sterilizing medical instruments, the sterilizer having a pressurizable chamber having an opening communicating therewith. A door is provided for closing and sealing the opening to the chamber. A sterilant inlet and a sterilant outlet communicate with the chamber. A container holds medical instruments to be sterilized. The container is comprised of a tray and a lid dimensioned to rest on the tray. The tray and lid define an interior area for holding medical instruments. The tray has connection means for connecting the sterilant inlet to the interior area of the tray when the tray is inserted in the chamber, and the lid is movable from the tray when pressurized sterilant is introduced into the cavity.

Abstract: A magnetic resonance imaging scanner includes a generally cylindrical main magnet assembly (10) that defines a cylinder axis (16). A first set of shims (60) are rigidly positioned inside the magnet assembly (10) at about a first distance (d1) relative to the cylinder axis (16). A second set of shims (62) are rigidly positioned inside the main magnet assembly (10) at about a second distance (d2) relative to the cylinder axis (16). The second distance (d2) is different from the first distance (d1). A generally cylindrical radio frequency coil (26) is arranged inside the main magnet assembly (10) at about a third distance (d3) relative to the cylinder axis (16). A plurality of gradient coils (20) are arranged inside the main magnet assembly (10) at about a fourth distance (d4) relative to the cylinder axis (16).

Abstract: An MRI apparatus is provided. The MRI apparatus includes a main magnet (12) for generating a main magnetic field in an examination region, a plurality of gradient magnets (16) for generating magnetic field gradients in the main magnetic field, a radio frequency coil (22) for transmitting radio frequency signals into the examination region and exciting magnetic resonance in a subject disposed therein, and a radio frequency coil for receiving the magnetic resonance signals from the subject. The MRI apparatus also includes subject support (52) for supporting the subject, a position controller (60) for controlling the position of the subject support within the examination region, and a position encoder (53) for directly measuring the position of the subject support.
