Abstract: A method and apparatus for performing image reconstruction using data obtained by an N beam helical scan, the method including generating projection data arrays for each of the N row in a CT detector, weighting the data arrays using a unique weighting function that is applicable to detectors having many different numbers of rows N to generate helical weighted arrays for each row, weighting the helical weighted arrays by applying a conjugate weighting function to generate conjugate arrays for each detector row and then combining the conjugate weighted arrays, filtering and back-projecting to generate a slice image.

Abstract: A preservation method for biological material having cell membranes includes microinjecting the cells with sugar; preparing the cells for storage; storing the biological material; and recovering the stored biological material from storage. Carbohydrate sugars such as trehalose, sucrose, fructose, dextran, and raffinose, may be used as bio-protective agents.

Abstract: 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.
