  • Patent number: 10633709
    Abstract: An apparatus and a method for diagnosing a tumor are provided. A histogram generating section generates a histogram from a result of a measurement of fluorescence intensity of a suspension produced from a target sample. The histogram indicates a relation between the fluorescence intensity and the number of cells. A determination section detects an S phase fluorescence intensity range corresponding to S phase cells based on the fluorescence intensity corresponding to a peak of the number of cells in the histogram, detects an abnormal fluorescence intensity range corresponding to tumor cells, based on a change in the number of cells in the S phase fluorescence intensity range, and performs a diagnosis of a tumor in the target sample based on an index of the number of cells in a range defined by excluding the abnormal fluorescence intensity range from the S phase fluorescence intensity range.

  • Publication number: 20150228454
    Abstract: A beam collimator includes a plurality of lens units that are arranged along a reference trajectory so that a beam collimated to the reference trajectory comes out from an exit of the beam collimator. Each of the plurality of lens units forms a bow-shaped curved gap and is formed such that an angle of a beam traveling direction with respect to the reference trajectory is changed by an electric field generated in the bow-shaped curved gap. A vacant space is provided between one lens unit of the plurality of lens units and a lens unit that is adjacent to the lens unit. The vacant space is directed in a transverse direction of the collimated beam in a cross section that is perpendicular to the reference trajectory. An inner field containing the reference trajectory is connected to an outer field of the plurality of lens units through the vacant space.

  • Patent number: 7687782
    Abstract: A beam deflection scanner performs reciprocating deflection scanning with an ion beam or a charged particle beam to thereby periodically change a beam trajectory and comprises a pair of scanning electrodes installed so as to be opposed to each other with the beam trajectory interposed therebetween and a pair of correction electrodes installed in a direction perpendicular to an opposing direction of the pair of scanning electrodes, with the beam trajectory interposed therebetween, and extending along a beam traveling axis. Positive and negative potentials are alternately applied to the pair of scanning electrodes, while a correction voltage is constantly applied to the pair of correction electrodes. A correction electric field produced by the pair of correction electrodes is exerted on the ion beam or the charged particle beam passing between the pair of scanning electrodes at the time of switching between the positive and negative potentials.
