  • DOSE DISTRIBUTION CREATING PROGRAM IN CONSIDERATION OF INFLUENCE OF MAGNETIC FIELD, DOSE DISTRIBUTION CREATING METHOD IN CONSIDERATION OF INFLUENCE OF MAGNETIC FIELD, AND DOSE DISTRIBUTION CREATING APPARATUS
    Publication number: 20230390583
    Abstract: In order to provide a dose distribution creating program in consideration of influence of a magnetic field, a dose distribution creating method in consideration of influence of a magnetic field, and a dose distribution creating apparatus, enabling dose calculation in a magnetic field faster and more accurately than in the related art, the dose distribution creating program in consideration of influence of a magnetic field causes a computer to acquire a captured image of a subject captured with a magnetic field and an electrical wave or a photon beam, a dose distribution not in a magnetic field, and a dose distribution in a magnetic field, and input the dose distribution not in a magnetic field and information based on the captured image to a learning model (171) including a plurality of layers and trained in advance using the dose distribution not in a magnetic field, the dose distribution in a magnetic field, and the information based on the captured image, and estimate the dose distribution in a magnetic fi

  • Failure detection apparatus, failure detection method, and non-transitory computer readable recording medium
    Patent number: 11030028
    Abstract: A failure detection apparatus (10) includes a RAM (125) and a controller (122) configured to execute processing related to detection of a physical quantity in a predetermined sampling period (T1). The RAM (125) includes partitioned areas generated by partitioning the entire area of the RAM (125). The controller (122) is configured to execute sequential failure detection on a portion of the partitioned areas during a time when the controller (122) is not executing the processing in each of the sampling periods (T1).
