  • Patent number: 11446520
    Abstract: Through the present invention, three-dimensional coordinates of a tracking object moving in an irradiation object can be calculated from fluoroscopic X-ray images captured and acquired from various angles in a single fluoroscopic X-ray device mounted to a radiation therapy apparatus. The three-dimensional coordinates of the tracking object are calculated on a straight tracking object presence line connecting an X-ray generating device for fluoroscopy and the position in an X-ray plane detector of the tracking object on the fluoroscopic X-ray image acquired by the X-ray generating device for fluoroscopy and the X-ray plane detector, and using line segment information included in a movement region of the tracking object set in advance.

  • Patent number: 11439848
    Abstract: A template matching is performed on two fluoroscopic images by using a template image prepared in advance and a position corresponding to a high matching score is listed as a candidate for the position of a marker 29. From two lists of the candidates of the position of the marker 29, the lengths of common vertical lines for all combinations are calculated. Then, the position of the marker 29 is detected based on the matching score and the common vertical line. Then, based on the detected position of the marker 29, an amount of a proton beam to be irradiated to a target is controlled. Therefore, a tracking target can be accurately detected even when the conditions for X-ray fluoroscopy is severe, e.g., a thick object.

  • Patent number: 11441734
    Abstract: A method of producing a high-pressure tank including a liner and a reinforcement layer made of fiber-reinforced resin includes a process of forming at least a domed member included in the reinforcement layer. The process includes placing first fiber bundles to form a part of a protruding portion and a part of a domed main body, and placing second fiber bundles to cover the first fiber bundles. The first fiber bundles are placed, such that a fiber direction of the first fiber bundles in the protruding portion follows an axial direction of the protruding portion, and resin with which the fiber bundles are impregnated is solidified while the first fiber bundles are being placed. The second fiber bundles are placed, such that the fiber direction of the second fiber bundles intersects with the fiber direction of the first fiber bundles.

  • Publication number: 20220259686
    Abstract: A dephosphorization method using a top and bottom blown converter. This method uses a converter charged with molten iron and slag, to blow an oxygen-containing gas from a top-blowing lance, supply the gas from an inlet of a blowing hole, and supply a control gas from an opening toward an axial center. This method has: a slag top-surface position measurement step, with the top surface of the molten iron measured in advance, measuring an arbitrary position in a top surface of the slag; a slag top-surface difference calculation of slag thickness difference between the measured top-surface positions of the molten iron and the slag; and a jetting condition adjustment step of, using the obtained slag thickness, adjusting a jetting condition of the gas jetted from the top-blowing lance into an appropriate range. The top-blown jetting condition is adjusted by comparing the slag thickness and the depth of a surface depression.
