Abstract: Provided is a twin disc pump which includes split rod bearings for connecting pump discs to a drive shaft, and pedestal bearings that also receive the drive shaft. The split rod bearings can be disassembled without having to disassemble any portion of a housing of the pump. Accordingly, an operator can gain access to the split rod bearings, the pedestal bearings, and the drive shaft from above the pump without having to access the pump from below. The twin disc pump also includes a new attachment mechanism for connecting a top portion of the housing to an intermediate portion. The twin disc pump also includes a modified metal ring for improved leakage prevention and easier release. The twin disc pump may also be included within a system including a frame capable of locking the pump in different orientations.

Abstract: A method for collecting data for use in image reconstruction of an object being scanned, comprises providing a plurality of detectors disposed in an arc around the object being scanned to detect light passing through the object; impinging a laser beam at a point on the object; integrating the output of each detector at a number of successive time intervals, each time interval being longer than the previous time interval; digitizing the integrated output from each time interval; successively digitizing multiple times the integrated output from the longest time interval and averaging the results; orbiting the detectors and laser beam to another point on a circle; and repeating the above steps until a complete circle has been traversed.

Abstract: A scanner for a medical optical imaging device, comprises an illumination source positioned to direct emitted light into a breast positioned below a support surface; a plurality of detectors positioned to detect light emerging from the breast; and a container disposed below the illumination source and the detectors adapted to trap light reflected from the breast.
