    摘要: A technique for reducing noise in pixel images includes modifying initial image data to prevent subsequent image data loss, shrinking the modified image, processing the shrunken image with known segmentation-based filtering techniques which identify and differentially processing structures within the image. After processing, the shrunken image is enlarged to the dimensions of the initial data and subsequently processed to correct intensity irregularities and to preserve CT numbers. The resulting technique is versatile and provides greatly improved computational efficiency while maintaining image quality, allowing for dose reduction during imaging.

    摘要: Some configurations of the present invention thus provide a method for producing images of an object. The method includes dynamically helically scanning an object on a moving table utilizing a scanning imaging system. During the scan, projection views of the object are acquired and stored together with corresponding table locations. A plane for reconstruction of an image of the object is selected. The stored table locations are used to determine geometric variables applicable to the stored projection views; and the stored projection views are filtered and backprojected utilizing the geometrical variables to reconstruct an image of the object at the reconstruction plane.

    摘要: A transport medium for orderly, in-process transportation of assembled electrical devices during backend processing. A carrier tray is comprised of a plurality of carrier units held in coplanar relationship by a frame. Preferably the carrier units are polyethersulfone inserts latchable into a coordinate matrix of carrier unit holes defined by a metallic sheet. Each carrier unit carries one or more electrical devices in device seats which expose a top and a bottom of each device sufficiently to eliminate any necessity for removing the devices from the medium during all backend processing. Each carrier unit has a standardized perimeter but a core which is adapted to a particular device size and form, and there can be as many different carrier units as there are different device forms and sizes, but all carrier units fit into a standard carrier unit hole. The frames and carrier units are robotically manipulable. Each tray, each carrier unit and each device in a carrier unit are uniquely identifiable by a combination of bar code indicia on the frame and a series of indexing holes along the frame perimeter and centered on each line of carrier units.
