ALEXANDRIA, Va., Oct. 21 -- United States Patent no. 12,440,119, issued on Oct. 14.
"Stimulated-echo imaging for EPRI" was invented by Howard J. Halpern (Chicago) and Boris Epel (Chicago).
According to the abstract* released by the U.S. Patent & Trademark Office: "An apparatus and method for improved S/N measurements useful for electron paramagnetic resonance imaging in situ and in vivo, using high-isolation transmit/receive surface coils and temporally spaced pulses of RF energy (e.g., in some embodiments, a RF pi pulse) having an amplitude sufficient to rotate the magnetization by 180 degrees followed after varied delays, by a second RF pulse having an amplitude half that of the initial pulse to rotate the magnetization by, e.g., 90 deg...
