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.

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.

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.
