  • Publication number: 20200121391
    Abstract: A method for planning a bone grafting procedure includes the collection of imaging scan data of the target region and of a harvest region as a source for a bone graft complementary to the target region. Virtual bone model and harvest regions are generated. A computer processor determines at least one parameter for a bone graft model complementary to the target region. A location at the harvest region for the bone graft is identified based on the bone graft model. The location of the harvest region is registered to a first computer-assist device and the bone graft is harvested. The target region is registered to the first computer-assist device or another device. The cutting characteristics for the target region are communicated to the first computer-assist device or the other device to receive the bone graft. A surgical system for performing the computerized method is also provided.

  • Patent number: 4267961
    Abstract: Photocross-linkable, organic solvent-soluble polymers having a Tg greater than 200.degree. C. are disclosed. The polymers contain sufficient radiation-sensitive cross-linkable units to render the polymers insoluble in organic solvents on exposure to radiation to which the cross-linkable units are sensitive. Also disclosed are supports, particularly supports having a radiation-sensitive surface, having thereon a layer of the described photo-corss-linkable polymers. The polymers are capable of receiving heat-transferrable dyes and are useful in forming color filter arrays for solid-state imaging devices. A particularly convenient method of forming solid-state color imaging devices having a layer containing an array of color filters is also disclosed.

  • Patent number: 4239842
    Abstract: An improved color filter array comprises a transparent heat-transfer dye-receiving layer containing an array of filter elements wherein the dye-receiving layer is a certain polyester wherein at least 30 mole percent of the recurring units contain a saturated gem-bivalent radical having a saturated polycyclic three-dimensional structure that includes a saturated bicyclic atomic bridge hydrocarbon ring member. The improved dye-receiving layers provide filter elements with excellent edge sharpness. The improved color filter arrays are useful in color imaging devices, such as solid-state video cameras.
