Latest Patents

Cao holds a patent titled "Dynamic shim approach to correct eddy-currents and concomitant fields in magnetic resonance imaging using local shim coil." This patent describes a method for magnetic resonance imaging that includes performing a pre-scan using a spin-echo diffusion acquisition with a one-time MRI pulse sequence. The method measures phase differences between diffusion and non-diffusion acquisitions, which correspond to an estimation of eddy-current-induced phase in a diffusion-prepared sequence. The process involves applying arbitrary waveform shim currents to a shim array during the acquisition, determined from the measured phase differences to create opposite phase maps that compensate for eddy-current or system-imperfection-induced phase differences. This innovative technique enhances the accuracy and reliability of MRI scans.
