  • Patent number: 8395131
    Abstract: A method for high-dose Grid radiotherapy utilizing a three-dimensional (3D) dose lattice formation is described herein. The 3D dose lattice can be achieved by, but not limited to, three technical approaches: 1) non-coplanar focused beams; 2) multileaf collimator (MLC)-based intensity modulated radiation therapy (IMRT) or aperture-modulated arc; and 3) heavy charged particle beam. The configuration of a 3D dose lattice is comprised of the number, location, and dose of dose vertices. The optimal configuration of a 3D dose lattice can be achieved by manual calculations or by automating the calculations for a generic algorithm. The objective of the optimization algorithm is to satisfy three conditions via iteration until they reach their global minimum. With 3D dose lattice, high doses of radiation are concentrated at each lattice vertex within a tumor with drastically lower doses between vertices (peak-to-valley effect), leaving tissue outside of the tumor volume minimally exposed.

  • Patent number: 8233852
    Abstract: An apparatus may include a non-linear module, a control module, and a calibration module. The non-linear module produces an output signal from an input signal. The control module selects, upon an occurrence of a calibration condition, a calibration operation from two or more calibration operations. Each of the two or more calibration operations may generate one or more correction values for the non-linear module. Further, each of the calibration operations produces the input signal from a pre-input signal. This selected calibration operation is performed by the calibration module. The two or more calibration operations include a first calibration operation and a second calibration operation. The first calibration operation produces the input signal from the pre-input signal according to a predictive technique. The second calibration operation produces the input signal from the pre-input signal according to a non-predictive technique.

    Abstract: Techniques are disclosed for producing RF signals from baseband signals. For instance, an apparatus may include an intermediate frequency (IF) signal generation module, and an upconversion module. The IF signal generation module produces an analog IF signal from a digital baseband signal. In turn, the upconversion module generates a radio frequency (RF) output signal from the analog IF signal. The upconversion module may include a translational phase locked loop (PLL) to receive the analog IF signal and to produce the RF output signal. The RF output signal may be for transmission in a wireless communications network, such as a cellular network.
