Patent number: 11300695Abstract: A Time-Resolved PET imaging system for producing an event-by-event, real-time, high resolution, three-dimensional positron emission tomographic images without performing sinogram formation or image reconstruction. The third dimension is provided by measuring the ?T between the arrival times of gamma rays from a positron event being detected by two cooperating detectors. In order to determine the location of a positron event along the lines of response, the measurement includes a fast scintillator, constant fraction discriminator and the digital intervalometer. The arrival time of each photon in the annihilation process is recorded with respect to a clock frequency with picosecond resolution. This approach requires significantly fewer positron events, thus requiring fewer detectors, thereby resulting in an gamma event-by-gamma event, real-time TPET imaging system that is more efficient and more economical to produce than conventional PET systems.Type: GrantFiled: June 7, 2021Date of Patent: April 12, 2022Inventors: Ronald Nutt, Lynda J.

Patent number: 9686851Abstract: A target assembly to produce radioisotopes for the synthesis of radiopharmaceuticals. The target assembly includes a target vessel with a target chamber adapted to receive a target material. A thin cover sheet of particle-permeable material covers the target chamber. In a bombardment process, a high-energy particle beam generated by a cyclotron or particle accelerator strikes the thin cover sheet, whereby at least some of the particles from the particle beam penetrate to the target chamber so as to interact with the target material, altering the nuclear makeup of some of the atoms in the target material to produce radioisotopes.Type: GrantFiled: January 23, 2015Date of Patent: June 20, 2017Assignee: ABT Molecular Imaging Inc.Inventors: Ronald Nutt, David Patton, Sr., Darrell Swicegood, John McCracken, Mark Haig Khachaturian

Patent number: 9657407Abstract: A cantilever device for extending capacity of a scale used in a crystal growth apparatus having a pulling head wherein upward movement of a support column in the pulling head decreases a weight measured by the scale. The device includes a horizontal arm having first and second brackets, wherein the first bracket is attached to the pulling head. The device also includes a plate that extends through openings in the first and second brackets, wherein the plate includes a contact end and a free end. Further, the device includes a flexible element attached between the arm and the plate to form a pivot to enable rotation of the plate. A load is positioned on the plate wherein the load causes rotation of the plate about the pivot to cause upward movement of the contact end to move the support column upward to decrease weight measured by the scale.Type: GrantFiled: October 24, 2014Date of Patent: May 23, 2017Assignee: Siemens Medical Solutions USA, Inc.Inventors: Mark S.

Patent number: 8333952Abstract: A microfluidic radiopharmaceutical production system and process for synthesizing per run approximately, but not less than, one (1) unit dose of a radiopharmaceutical biomarker for use in positron emission tomography (PET). The radiopharmaceutical production system includes a reaction vessel that receives a radioisotope from an accelerator or other radioisotope generator. Organic and aqueous reagents are introduced into the reaction vessel, and the mixture is heated to synthesize a solution of a pre-selected radiopharmaceutical.
