  • Patent number: 10835764
    Abstract: A function/process of recording marker position data and spot data is provided. The marker position data includes position information of a marker 29 measured for tumor tracking irradiation and information on time of execution of X-ray imaging. The spot data includes information on time of irradiation of each spot, a delivered irradiation position, and a delivered irradiation amount. The marker position data and the spot data are synchronized based on the time information, and by using the marker position data and the spot data upon spot irradiation, a delivered dose distribution of proton irradiation is calculated. With this configuration, it is possible to take the influence of interplay effect into consideration, and it is possible to support to make more appropriate determination upon replanning of a treatment plan.

  • Publication number: 20110208032
    Abstract: Provided are a detection device and a detection method that are based on a novel principle and able to detect blood vessels and other various targets with high sensitivity and accuracy. A detection device includes: m electrodes that generate at least around one straight line m rotationally symmetric electric charges (m is an even number that is greater than or equal to 4) whose total amount of charge is substantially 0; and at least one electric field detection element that detects an electric field on the straight line. The m electric charges are a quadrupole, a planar hexapole, a planar octupole, a three-dimensional octupole and the like. In order to make the quadrupole, four electrodes (11 to 14) are disposed at the vertexes of a square. At the center of these electrodes (11 to 14), a detection electrode (20) is disposed. The detection device is used in making up a vein sensing device and the like.
