Publication number: 20220072324Abstract: A device, system and method for creating pulsed electric fields with good uniformity are provided. The electric fields occupy a large volume, suitable for placing a human or animal patient. A device for generating the electric fields is provided, which comprises one or more toroidally or cylindrically shaped magnetic core(s) wound with electrical wires, which, when pulsed with electrical currents, generate an electric field of high uniformity in the interior region of the toroidal or cylindrical cores. These electric field pulses, when used in conjunction with pharmacological agent, destroy cancer cells through a process called Targeted Osmotic Lysis.Type: ApplicationFiled: December 2, 2019Publication date: March 10, 2022Applicants: Board of Supervisors of Louisiana State University and Agricultural and Mechanical College, The Phantom Laboratory, IncorporatedInventors: Dennis J. Paul, Harry J. Gould, Richard Philip Mallozzi

Patent number: 8024025Abstract: An apparatus and method for correcting magnetic resonance temperature measurements is disclosed. In one aspect, the method identifies monitoring regions of interest outside a therapeutic region of interest. Next, a pulse sequence sensitive to changes in T1 and proton density is used to measure the temperature changes in these regions. Next, the PRFS is measured in these same regions. The PRFS in these regions will be caused both by the desired shift from temperature change, and the undesired shift from background magnetic field changes. Using the measured temperature changes from the T1-method, the component of the PRFS due to actual temperature changes is subtracted from the PRFS method, leaving only the component caused by the unwanted magnetic field changes. This analysis is performed separately for each region. At the end of this step, one has measured the change in background magnetic field within each region.Type: GrantFiled: May 5, 2008Date of Patent: September 20, 2011Assignee: General Electric CompanyInventors: Richard Philip Mallozzi, Charles Lucian Dumoulin
