    摘要: 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.

    摘要: Systems, apparatuses and methods may provide font substitution based on a custom font. In one example, a custom handwritten font may be generated based on a comparison between handwritten sample text and training text. In another example, handwritten original text may be converted to unique machine text based on a substitution of the handwritten original text with the custom handwritten font. Thus, a user's handwriting may be converted to the user's own best or preferred handwriting.

    摘要: A low cost, low power consumption scalable architecture is provided to allow a computer system to be managed remotely during all system power states. In a lowest power state, power is only applied to minimum logic necessary to examine a network packet. Power is applied for a short period of time to an execution subsystem and one of a plurality of cores selected to handle processing of received service requests. After processing the received service requests, the computer system returns to the lowest power state.
