ALEXANDRIA, Va., June 12 -- United States Patent no. 12,298,375, issued on May 13, was assigned to O2M Technologies LLC (Chicago).

"Pulse sequence for resonance-based tissue analysis" was invented by Boris Meerovich Epel (Chicago) and Mrignayani Kotecha (Chicago).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method for relaxation time determination includes delivering a series of radio frequency (RF) pulses in a sequence to a specimen having a magnetic resonance spin system. The pulses are separated by equal time intervals and the sequence has a duration comparable or greater than a spin-lattice relaxation time for the spin system. The method includes receiving a response after each RF pulse in the series....
