Latest Patents
John Star-Lack holds a patent for a method of improved magnetic resonance spectroscopic localization using spectral-spatial pulses. This invention utilizes spectral-spatial 180° refocusing pulses in the point resolved spectroscopy (PRESS) localization sequence. The PRESS sequence employs a series of three pulses with a tilt angle pattern of 90°-180°-180°. The first excitation pulse is a spatially selective 90° tilt angle pulse. The subsequent two pulses are spectral-spatial refocusing pulses that provide multi-dimensional selectivity. This feature allows for enhanced solvent suppression, reduced chemical shift-induced spatial displacement, and the ability to refocus weakly coupled spins. In a preferred embodiment, the spectral-spatial pulses are time-asymmetric and identical, resulting in a linear phase profile through phase compensation between the two refocusing pulses. Alternatively, a linear phase profile can be achieved using time-symmetric refocusing pulses. The time-asymmetric feature is preferred as it results in lower applied RF power and shorter echo times.
