  • Patent number: 10352880
    Abstract: This disclosure presents systems for x-ray microscopy using an array of micro-beams having a micro- or nano-scale beam intensity profile to provide selective illumination of micro- or nano-scale regions of an object. An array detector is positioned such that each pixel of the detector only detects x-rays corresponding to a single micro- or nano-beam. This allows the signal arising from each x-ray detector pixel to be identified with the specific, limited micro- or nano-scale region illuminated, allowing sampled transmission image of the object at a micro- or nano-scale to be generated while using a detector with pixels having a larger size and scale. Detectors with higher quantum efficiency may therefore be used, since the lateral resolution is provided solely by the dimensions of the micro- or nano-beams. The micro- or nano-scale beams may be generated using an arrayed x-ray source or a set of Talbot interference fringes.

  • Publication number: 20070276228
    Abstract: A computer system and a computer-implemented method are provided for interactively displaying a three-dimensional rendering of a structure having a lumen and for indicating regions of abnormal wall structure. A three-dimensional volume of data is formed from a series of two-dimensional images representing at least one physical property associated with the three-dimensional structure. An isosurface of a selected region of interest is created by a computer from the volume of data based on a selected value or values of a physical property representing the selected region of interest. A wireframe model of the isosurface is generated by the computer wherein the wireframe model includes a plurality of vertices. The vertices are then grouped into populations of contiguous vertices having a characteristic indicating abnormal wall structure by the computer. The wireframe model is then rendered by the computer in an interactive three-dimensional display to indicate the populations of abnormal wall structure.

  • Publication number: 20070179815
    Abstract: Systems and methods for screening large client populations (e.g., students) to identify those clients susceptible to a medical condition (e.g., a cardiac condition) are provided. In general, the system allows for a large number of clients to be tested at a convenient location (e.g., a school), on-site identification of those clients at immediate risk, and over-read of each test result (both normal and abnormal test results) at a later date by a physician capable of gaining access to the records via a secure computer connection. The system further includes various servers and network connections capable of creating and maintaining a secure central database, creating and updating electronic client medical records, down-loading data (e.g., the electronic records) from the central database to portable computing units, collecting client testing data, up-loading and integrating the testing data into the secure central database, and providing secure access to authorized end-users.

  • Publication number: 20070142526
    Abstract: Use of the barrier property effect of nanomaterials to improve the electrical insulation resistance and corrosion protection strength properties of electromagnetic devices. The beneficial effects are realized with nanomaterial loadings of 1-20%, and preferably between 1-5%, parts by weight of coating resins. Nanomaterials include, but are not limited to, silica, alumina, zirconia, and antimony pentoxide, which are dispersed either directly into a coating, or pre-dispersed in a carrier appropriate to the solvent of the resin system. The rheology of the resin system is not significantly altered which would otherwise affect processing of the resins for their intended applications.

    Abstract: Use of the barrier property effect of nanomaterials to improve the electrical insulation resistance, corrosion protection and bond strength properties of electromagnetic devices. The beneficial effects are realized with nanomaterial loadings of 1-20%, and preferably between 1-5%, parts by weight of coating resins. Nanomaterials include, but are not limited to, silica, alumina, zirconia, and antimony pentoxide, which are dispersed either directly into a coating, or pre-dispersed in a carrier appropriate to the solvent of the resin system. Resulting formulations benefit from the fact anti-settling agents need not be incorporated into the resin to keep the inorganic material suspended. Also, the rheology of the resin system is not significantly altered which would otherwise affect processing of the resins for their intended applications.

  • Publication number: 20060173708
    Abstract: A method of providing health care by establishing a predetermined patient population grouped by geographic regions where the patient population has access to a traveling healthcare professional that may travel to the patient's location. The healthcare professional evaluates and examines the patient using a plurality of technologies including a microprocessor and memory storage that is coupled to, or interfaced with, audio/video/data transfer and communications systems, medical devices, and other vital measurement devices that the physician located at the physicians' center uses to assess and consult the healthcare professional who is onsite with the remote patient. During the exam the healthcare professional uses audio/video/data communications for interconnecting the healthcare professional with a physician at the physicians' center.
