Publication number: 20230190211Abstract: Described herein is a positron emission tomography (PET) detector array that has a plurality of detector elements, with each detector element mounted on a resilient, rigid support surface. A detector element movement system is connected to each rigid support surface, so that each detector element can be moved independently. This allows for the relative position of the individual detectors to be changed during imaging so that the imaging window can be increased or decreased during imaging, thereby allowing for improved, better resolution imaging of smaller volumes if desired.Type: ApplicationFiled: July 15, 2021Publication date: June 22, 2023Inventors: James Schellenberg, John Saunders

Patent number: 11653996Abstract: Apparatus for imaging during surgical procedures includes an operating room for the surgical procedure and an MRI for obtaining images periodically through the surgical procedure by moving the magnet up to the table. The magnet wire is formed of a superconducting material such as magnesium di-boride or Niobium-Titanium which is cooled by a vacuum cryocooling system to superconductivity without use of liquid helium. The magnet weighs less than 1 to 2 tonne and has a floor area in the range 15 to 35 sq feet so that it can be carried on the floor by a support system having an air cushion covering the base area of the magnet having side skirts so as to spread the weight over the entire base area. The magnet remains in the room during surgery and is powered off to turn off the magnetic field when in the second position remote from the table.Type: GrantFiled: January 20, 2020Date of Patent: May 23, 2023Assignee: Sino Canada Health Engineering Research Institute (Hefei) Ltd.Inventors: Gong Zhang, Haoqin Zhu, Gordon A.
