  • Patent number: 7844090
    Abstract: A method of deriving a quantitative measure of a degree of calcification of a blood vessel such as an aorta by processing an image such as an X-ray image of at least a part of the blood vessel containing said calcification comprises: taking a starting set of digital data representative of an image of at least part of a blood vessel containing a calcification set against a background; estimating the boundary of the calcification; using inpainting to replace digital data in said starting set representing the calcification with data extrapolating the boundary of the background to extend over the area of calcification, and so generating an inpainted set of digital data; and computing the difference between the starting set of digital data and the inpainted set of digital data to obtain a quantitative measure of the degree of calcification of the blood vessel.

  • Publication number: 20080190435
    Abstract: A nasal cannula apparatus that is particularly well suited for use with infants and small children. The apparatus includes a soft, close fitting knitted cap that supports elongated flexible oxygen tubes in a comfortable and secure manner about the infant's head. The knitted cap readily adjusts to the size of the infant's head and effectively remains in position about the infant's head as the infant moves about in its crib or infant bed.

  • Publication number: 20030217502
    Abstract: The sink line comprises a plurality of weights attached to a longitudinal supporting structure, preferably in a spaced a part relationship, the weights comprising a core member of a first material entirely enclosed in a coating of a second material, the weights having an outer surface in securing engagement with the supporting structure.

  • Publication number: 20010001511
    Abstract: A method of producing a polyphosphate, orthophosphate, phosphonate or the like chemical treatment cake is disclosed. Conventional commercially available treatment material is obtained in powder form and mixed with water to initiate an exothermic reaction. The material is then poured into a mold and placed inside an insulated hermetic cabinet and allowed to quiescently cool in the passive environment of the cabinet. The cake is harder, more uniform and relatively free of inclusions compared to cakes formed by other methods.
