Latest Patents

Ramasawmy holds a patent titled "Methods and systems for Maxwell compensation for spin-echo train imaging." This patent describes methods, computing devices, and MRI systems that effectively reduce artifacts produced by Maxwell gradient terms in turbo spin echo (TSE) imaging. The technology involves generating a radiofrequency (RF) excitation pulse to produce transverse magnetization, which in turn generates a nuclear magnetic resonance (NMR) signal. A series of RF refocusing pulses are utilized to create corresponding NMR spin-echo signals. The original encoding gradient waveform is modified by adjusting a portion of it or introducing a zero zeroth-moment waveform segment at the ends. During intervals adjacent to the RF refocusing pulses, a first gradient pulse is generated according to the modified gradient waveform. An image is constructed from the digitized samples of the NMR spin-echo signals obtained.
