摘要： An improved anatomical visualization system which is adapted to augment a standard video endoscopic system with a coordinated computer model visualization system so as to enhance a physician's understanding of the patient's interior anatomical structure. A database defining a 3-D computer model comprises at least a first software object corresponding to the anatomical structure. A second software object having a surface is placed in registration with the first software object such that they coexist in a single coordinate system. A movable sensor, such as an endoscope, acquires a real-time video image which is texture mapped onto the surface of the second software object. A processing device is provided to generate an image from the first and second registered software objects taken from any specified point of view relative to the single coordinate system.

摘要： An embodiment of the present invention includes a plurality of portable satellite terminals (PSTs) and a network control unit (NCU) in mutual communication by a communications satellite. Integrated services digital network (ISDN) basic rate interfaces (BRI) are provided at each PST and NCU such that commercially available equipment may be connected and link access procedure D-channel (LAPD) protocols are supported end-to-end. CCITT Recommendation V.42 link access procedure-modem (LAPM) with the selective frame reject option is used to carry whole LAPD frames within the information fields of LAPM frames over the satellite link. Protocol conversion units are employed at each PST and NCU to convert LAPD to LAPM and back again.

摘要： Improved cellulose semipermeable hollow fibers useful in detoxifying blood during hemodialysis or hemofiltration treatments. The cellulose fibers are fine, capillary fibers that are made by melt extrusion of certain cellulose ester polyol melt spin compositions into self-supporting gelled fibers. The cellulose ester gelled fibers are subsequently chemically converted into cellulose fibers by deacetylation, in aqueous alkali solution. The product fibers exhibit improved wet intrinsic tensile strength and higher water permeability characteristics than heretofore known cellulose fibers made from cellulose ester spin compositions.The invention includes the method of making the improved fibers and separatory cells such as hemodialyzers or hemofilters which contain the improved fibers in a gamma ray sterilized condition.
