  • Patent number: 10782935
    Abstract: A method and apparatus for generating an application flow logic are disclosed which include performing an initialization process based on storage of at least one software toolbox in a toolbox list of a computer memory device; parsing an application description into a series of module descriptors; creating a module primitive defined in a dictionary as a data string representing a name of a tool in the software toolbox, and a data string for least one of: an input, an output, or a data string; producing a module for each module primitive, an input to each tool being produced as an output of another tool; assembling an application flow logic as a combination of produced modules; and providing access to the application flow logic for execution as a combination of calls to the produced modules stored in the computer memory device.

  • Patent number: 8981779
    Abstract: Active resistive shim coil assemblies may be used in magnetic resonance imaging (MRI) systems to reduce in-homogeneity of the magnetic field in the imaging volume. Disclosed embodiments may be used with continuous systems, gapped cylindrical systems, or vertically gapped systems. Disclosed embodiments may also be used with an open MRI system and can be used with an instrument placed in the gap of the MRI system. An exemplary embodiment of the active resistive shim coil assembly of the present disclosure includes active resistive shim coils each operable to be energized by separate currents through a plurality of power channels. In some embodiments, the disclosed active resistive shim coil assemblies allow for various degrees of freedom to shim out field in-homogeneity.

  • Publication number: 20070246578
    Abstract: A showerhead has at least a first set of nozzles and a second set of nozzles for discharging water. The showerhead discharges water according to one of multiple water delivery functions, where a first water delivery function corresponds to water being discharged through only the first set of nozzles, a second water delivery function corresponds to water being discharged through only the second set of nozzles and a third water delivery function corresponds to water being discharged through the first and second sets of nozzles simultaneously. The spacing between the first set of nozzles and the second set of nozzles is carefully selected so that the third water delivery function corresponds to the integrated nozzles of the first and second sets of nozzles. As a result, the third water delivery function provides a coherent and balanced water flow resulting in a more pleasant feel.

  • Publication number: 20050207531
    Abstract: A method of determining a treatment plan for intensity modulated radiation treatment (IMRT) divides a three-dimensional volume of a patient into a grid of dose voxels. At least a portion of the dose voxels are designated to belong to at least one target or to at least one critical structure. An ionizing radiation dose as delivered by a plurality of beamlets each having a beamlet intensity is modeled. A non-linear convex voxel-based penalty function model is provided for optimizing a fluence map. The fluence map defines the beamlet intensities for each of the plurality of beamlets. The model is then solved based on defined clinical criteria for the target and the critical structure using an interior point algorithm with dense column handling to obtain a globally optimal fluence map.

  • Publication number: 20050197564
    Abstract: A device and a process for performing high temporal- and spatial-resolution MR imaging of the anatomy of a patient during intensity modulated radiation therapy (IMRT) to directly measure and control the highly conformal ionizing radiation dose delivered to the patient for the treatment of diseases caused by proliferative tissue disorders. This invention combines the technologies of open MRI, multileaf-collimator or compensating filter-based IMRT delivery, and cobalt teletherapy into a single co-registered and gantry mounted system.
