Abstract: An open architecture platform superconducting magnet for international procedures with a shaped yoke assembly and associated magnet coil and with a patient support positioned above the magnet coil, and a magnetic field imaging volume which is conically shaped with a cross section which decreases in size remote from the coil.

Abstract: A collimator 100 for use in a radiation imaging system 10, and a method for making such collimators, are provided, wherein the collimator 100 is capable of collimating radiation in two orthogonal planes. The collimator in one embodiment includes a block 101 of radiation absorbing material having a plurality of focally aligned channels 102 extending therethrough; in a second embodiment, the collimator includes first and second collimation 204, 212 sections having a respective first plurality of focally aligned plate sets 201 and a respective second plurality of focally aligned plate sets 203 disposed orthogonally to the first plurality of plate sets. The method for making the collimator includes generating a CAD drawing, generating from the CAD drawing one or more stereo-lithographic files, and using the stereo-lithographic files to control an electro-deposition machining machine which creates the channels in the block.

Abstract: A curable masking material for protecting a passage hole in a metal-based substrate is formed of an extrudable resin composition. The resin composition is thermally stable at elevated temperatures, and does not serve as an adhesion site for any coatings which are applied over the masking material. In addition, the resin composition has non-Newtonian flow characteristics and is adapted to form a protrusion extending from the passage hole upon extrusion to fill the passage hole.

Abstract: To determine electrical resistance of an ohmic contact between a flexible printed circuit and a metallized layer upon a substrate of piezoelectric material, the printed circuit is provided with two exposed metal pads, in close proximity to each other, and two electrical leads from each pad to locations on the printed circuit that are accessible for probing with a four-lead resistance meter. For measurement of contact resistance in process development and process capability studies, many sets of such pads, of a variety of sizes, may be combined into a single printed circuit. For in-process monitoring of transducer manufacturing, a small number of contact resistance measurement pads may be designed into production printed circuits.

Abstract: A turbine inner shroud and a turbine assembly. The turbine assembly includes a turbine stator having a longitudinal axis and having an outer shroud block with opposing and longitudinally outward facing first and second sides having open slots. A ceramic inner shroud has longitudinally inward facing hook portions which can longitudinally and radially surround a portion of the sides of the outer shroud block. In one attachment, the hook portions are engageable with, and are positioned within, the open slots.

Abstract: A gamma ray collimator assembly comprising a first portion and a second collimator portion, the first and second portions having different gamma ray acceptance angles.
