  • Publication number: 20240130637
    Abstract: System and method for sensing movement such as chest movement of each of a plurality of target test subjects by: transmitting, at each of N transmitting antennas (TXs) of a phased multiple-input multiple-output (phased-MIMO) radar, a common frequency modulated continuous wave (FMCW) signal in each of a plurality of time division multiplex (TDM) slots, each TDM slot having associated with it a respective weight selected in accordance with a transmit steering vector configured to cause a coherent summation of transmitted signal in a desired direction ?0 toward at least one target; receiving target-reflected energy associated with the transmitted FMCW signals at a virtual array formed by stacking signal from P TDM slots received via M receiving antennas (RXs) of the phased-MIMO radar; and processing an output of the virtual array to extract therefrom signal received from the desired direction ?0 to determine thereby target movement in the desired direction ?0.

  • Patent number: 11826560
    Abstract: A computer-implemented method for generating a radiation therapy treatment plan for a volume of a patient, the method comprising: receiving an image of the volume; receiving at least one dose-distribution-derived function configured to provide a value as an output based on, as input, at least part of a dose distribution defined relative to the image; receiving a first probability distribution and at least a second, different, probability distribution, the first and at least second probability distributions; defining a multi-criteria optimization problem comprising at least a first objective function based on the at least one dose-distribution-derived function, the first probability distribution and a loss function; and a second objective function based on the at least one dose-distribution-derived function, the second probability distribution and the loss function; and performing a multi-criteria optimization process based on the at least two objective functions to generate at least two output treatment plans

  • Publication number: 20230117544
    Abstract: A method and apparatus for generating a radiation treatment plan for a volume comprising: receiving a first treatment plan upon which to base a second treatment plan, the first treatment plan indicative of a dose distribution; receiving at least one dose-distribution-derived function configured to provide a value based on at least part of the dose distribution; receiving a target for the respective value of each dose-distribution-derived function comprising receiving a probability distribution; determining an optimization problem, wherein the or each objective function is a function of the dose-distribution-derived function, the respective probability distribution and a respective loss function; performing the optimization process based on said optimization problem; and determining said second treatment plan.

  • Patent number: 11167153
    Abstract: A method of obtaining an interpolated treatment plan is based on interpolating between associated dose distributions through optimization with respect to an optimization problem comprising optimization functions based on deviations from clinical goals. The method may suitably be used to improve navigated plans resulting from multi-criteria optimization.

  • Patent number: 10130105
    Abstract: A bone-meat separator includes a chassis, a driving mechanism, a transmission shaft, a spiral shaft, a feed hopper, a pressurization portion and a bone-meat separation portion. In this design, a separation spiral shaft portion is a conical spiral shaft; the bone-meat separation portion is a conical component coaxially sheathed on the periphery of the separation spiral shaft portion, and an inner wall of the bone-meat separation portion is in clearance fit with an outer wall of the separation spiral shaft portion. With regard to the bone-meat separator, since the inner wall of the bone-meat separation portion and the outer wall of the spiral shaft are always in a stable clearance fit state, the service life is improved.
