  • Publication number: 20080087833
    Abstract: A multi-modality detection system and method for detecting medically-related conditions is disclosed. In some respects, the system and methods rely on at least two different modalities for imaging a region of interest including a patient organ such as the breast, brain, or other object within the region of interest. The two or more modalities are enabled with respective detectors as described herein and a respective output of each is collected and formed into a combined (fused) output representative of the plurality of different imaging modalities to enable imagine, diagnosis, study, or treatment of the medical condition.

  • Publication number: 20060239398
    Abstract: A new method of breast imaging to improve the detection of cancer during early stages of development is disclosed. The system combines molecular images of radioisotope uptake in cancerous cells with three dimensional high resolution single photon emission computed tomography (SPECT), positron emission tomography (PET), x-ray computed tomography (CT) and optical reflectance and emission (ORE) images of the breast. The system acquires data from nuclear isotopes within the breast and processes the data into three dimensional molecular tomographic images of cancerous cellular activity, morphological three dimensional x-ray density tomographic images and three dimensional optical surface images.

  • Patent number: 4774036
    Abstract: A color ringed or rimmed edge intraocular lens for implant in either the anterior chamber, the posterior chamber or the cornea of the eye. The lens has a colorless or clear central region of a material such as polymethylmethacrylate (PMMA) and a peripheral surrounding portion of a dark material such as blue PMMA. Polysulfone can also be utilized. The lens can be fabricated by passing a clear rod of optical quality PMMA through an extrusion orifice and coating the circumference of the rod with a layer of predetermined thickness of colored, preferably blue PMMA or other compatible material. Other methods of fabrication can include the introduction of a suitable dye into the outer regions of the rod, or joining the clear central region to a ring of colored material by thermal adhesive bonding or other known processes.

  • Patent number: 4730668
    Abstract: A radiator of the type having an upper water tank, a lower water tank, and a plurality of core radiator modules positioned between the upper and lower tanks with the use of a rubber gasket type seal, the core assembly with upper and bottom tanks secured as a unit with a pair of side frames interconnecting the tanks and core elements, the improvement comprising method and apparatus for replacing the internal module core units with a single conventional replacement core, which would include providing the replacement core in place of the modular units, providing an adaptor assembly connectably engageable onto the top face of the replacement core, the adaptor assembly having a plurality of upper nipples for accommodating the rubber gasket type seals so that the upper water tank and lower water tank can be utilized with the replacement core and the left and right side framework can re-engage the water tanks to provide the new radiator assembly utilizing the replacement core.

  • Patent number: 4661108
    Abstract: Intraocular lens including a meniscus lens optic with a convex anterior surface, a concave posterior surface and a double barrier ledge. The double barrier ledge includes an interrupting channel. A plurality of loops, such as continuously curved J-shaped blue loops, secure at an angle of 0.degree.-10.degree. to the plane of the optic. The double barrier ledge, including the U-shaped channel or other geometrically configured channel between the two ledges, provides a double barrier ledge like seal around the posterior capsule of the eye holding back migration of the cortical epithelium. The double barrier ledge causes a seal which prevents aqueous flowing back to the optical zone of the capsular bag. In the case of a dissection or laser capsulotomy, the double barrier seal prevents vitreous strands from passing beyond and inner edge of the ledge. Other optics for lenses, such as plano-convex or bi-convex, can utilize the double ledge principle.
