International Classification:

B01D 6306

US Classification:

210192

Abstract:

A device which serves as an artificial pancreas comprises a hollow fiber having an inner diameter of about 5 mm which is surrounded by islets of Langerhans enclosed in a housing. The islets are suspended in a semi-solid matrix which ensures desired distribution of the cells about the hollow fiber. The hollow fiber and suspended islets are enclosed in a housing which further aids the desired distribution of islets about the hollow fiber. The hollow fiber has a porosity which selectively allows passage of substances having a molecular weight of less than about 100,000 Daltons. The semi-solid matrix in which the islets are embedded and suspended is formed of an appropriate supporting material such as alginate or agar.

Assignee:

Raytheon Company - Lexington MA

International Classification:

G01T 116

US Classification:

250363S

Abstract:

A radiographic imaging system coupled to a movable table for repositioning subject matter at the conclusion of a scanning of an area of the subject matter. The imaging system is further coupled to a plural axis recording system in which a recording implement, such as a flashing light source, is driven in synchronism with a scanning motion of the imaging system along a recording medium such as a photographic film. Controller circuitry is coupled between the movable table, the imaging system and the recording system for synchronizing their respective operations and for selectably scaling the movement of a drive unit relative to the movement of the scanning. A large subject such as a complete human being may be scanned by repositioning the subject and the movable table at the conclusion of each of a sequence of area scans of the imaging system, and by scaling the output of the scanning system so that the successively scanned regions of the subject can be recorded upon a single standard size x-ray film plate.
