Patent number: 9827446Abstract: Photon-based radiosurgery is widely used for treating local and regional tumors. The key to improving the quality of radiosurgery is to increase the dose falloff rate from high dose regions inside the tumor to low dose regions of nearby healthy tissues and structures. Dynamic photon painting (DPP) further increases dose falloff rate by treating a target by moving a beam source along a dynamic trajectory, where the speed, direction and even dose rate of the beam source change constantly during irradiation. DPP creates dose gradient that rivals proton Bragg Peak and outperforms Gamma Knife® radiosurgery.Type: GrantFiled: December 22, 2016Date of Patent: November 28, 2017Assignees: STC.UNM, The Regents of the University of CaliforniaInventors: Shuang Luan, Lijun Ma, Zhe Chen

Publication number: 20170190338Abstract: A mounting structure for equipment compartment bottom plate is provided. The bottom plate is detachably connected to a skeleton boundary beam of the equipment compartment. A sliding rail is fixedly connected to a side of the bottom plate where the bottom plate is lap-jointed to a skeleton lateral beam of the equipment compartment. One of the sliding rail and the skeleton lateral beam is provided with a recess and the other is provided with a protrusion engaged with the recess. In the mounting structure, the connection of the bottom plate and the skeleton lateral beam is achieved by the engagement of the recess and the protrusion. Therefore, connecting pieces for connecting the bottom plate and the skeleton lateral beam are removed and the number of the connecting pieces is significantly reduced.Type: ApplicationFiled: November 16, 2015Publication date: July 6, 2017Applicant: CRRC QINGDAO SIFANG CO., LTD.Inventors: Wenmin YU, Zhaohua WANG, Shuhai LI, Yonglin SHAN, Zhicheng GUO, Aiqin TIAN, Guizhen YAN, Lijun MA, Sansan DING, Jianying LIANG

Patent number: 9630023Abstract: The present invention is a method and system for developing a dynamic scheme for Gamma Knife radiosurgery based on the concept of “dose-painting” to take advantage of robotic patient positioning systems on the Gamma Knife C and Perfexion units. The spherical high dose volume created by the Gamma Knife unit will be viewed as a 3D spherical “paintbrush”, and treatment planning is reduced to finding the best route of this “paintbrush” to “paint” a 3D tumor volume. Under the dose-painting concept, Gamma Knife radiosurgery becomes dynamic, where the patient is moving continuously under the robotic positioning system.Type: GrantFiled: December 16, 2013Date of Patent: April 25, 2017Assignee: STC.UNMInventors: Shuang Luan, Nathan Swanson, Lijun Ma

Patent number: 8972505Abstract: Techniques for synchronizing personal contact information with or from different sources are disclosed. Through a website (i.e., a server or system), all fractional personal contact information is consolidated, synchronized, processed or updated. In return, any of the resources may be synchronized to get a copy of the latest version of the contact information.
