Publication number: 20210031055Abstract: Various examples of methods, systems, apparatus and devices are provided for MRI adaptation for radiotherapy machines. In one example, a system for MRI-guided radiotherapy can include a mounting ring and superconducting magnets. The mounting ring can be installed on a gantry of a LINAC to rotate about an isocenter of the LINAC moving with the gantry. The first and second superconducting magnet can be positioned substantially parallel to each other at a separation distance with the centers substantially aligned. The first and second superconducting magnets can provide a main magnetic field within a region of interest located between the first and second superconducting magnets. The superconducting magnets can have an aperture positioned at the center of each magnet and can allow a radiotherapy beam emitting from the gantry head to pass through the apertures. In another example, superconducting magnets can be installed at opposite ends of a LINAC gantry.Type: ApplicationFiled: April 11, 2019Publication date: February 4, 2021Inventors: Steve Bin Jiang, Xun Jia, Ge Wang, Hak Choy, Nima Hassan-Rezaeian, Chenyang Shen

Patent number: 8724888Abstract: A dice recognition system and a dice recognition method for uncontrolled environments are provided. In the present invention, the number of dot on a dice is automatically recognized in an uncontrolled environment by using multiple cameras. The present dice recognition system is different in at least two aspects from any existing automatic dice recognition system which uses a single camera for recognizing dice in an enclosed environment. Firstly, an existing automatic dice recognition system uses a single camera to obtain planar images for dice recognition, while the present dice recognition system uses multiple cameras to obtain different viewpoints images for dice recognition. Secondly, the present dice recognition system is designed for uncontrolled environments, and which can be applied to an open-table game in a general gambling place for dice recognition without changing the original dice, dice cup, and other related objects.Type: GrantFiled: May 30, 2011Date of Patent: May 13, 2014Assignee: National Taiwan University of Science and TechnologyInventors: Gee-Sern Hsu, Xun-Jia Zhang
