Steven P. Allen is a notable inventor based in Charlottesville, VA, who has made significant contributions to the field of magnetic resonance imaging (MRI). With a total of two patents to his name, Allen's work focuses on enhancing imaging techniques and thermometry methods that have the potential to improve medical diagnostics.

Latest Patents

Allen's latest patents include "Methods and systems for spin-echo train imaging using spiral rings with retraced trajectories." This invention discloses methods, computing devices, and MRI systems that enhance image quality in turbo spiral echo (TSE) imaging. The technology generates a TSE pulse sequence that incorporates a series of radio frequency (RF) refocusing pulses, producing a corresponding series of nuclear magnetic resonance (NMR) spin echo signals. A gradient waveform is generated, comprising a spiral ring retraced in-out trajectory, which encodes the NMR spin echo signals. An image is constructed from digitized samples of these signals, significantly improving the imaging process.

Another patent by Allen is titled "Systems and methods for magnetic resonance based skull thermometry." This invention describes systems and methods for MR-based thermometry, which includes acquiring MR data in an area of interest of a subject heated by focused ultrasound (FUS) applied to the brain. The method utilizes a variable flip-angle T1 mapping sequence to gather T1 values over time, allowing for the determination of temperature changes in the area of interest, which are influenced by the applied FUS.
