ALEXANDRIA, Va., Oct. 6 -- United States Patent no. 12,754,272, issued on Oct. 6, was assigned to SHANGHAI JIAO TONG UNIVERSITY (Shanghai).

"Echo planar imaging method capable of reducing image distortion" was invented by Zhiyong Zhang (Shanghai) and Hao Chen (Shanghai).

According to the abstract* released by the U.S. Patent & Trademark Office: "An echo planar imaging method capable of reducing image distortion is provided. Two radio frequency (RF) pulses Alpha and Beta are used to respectively flip over a longitudinal magnetization into a transverse plane at different moments, so as to obtain observable transverse magnetization; the transverse magnetization obtained by flipping over the longitudinal magnetization by means of Alpha and Be...
