Latest Patents

One of his latest patents is focused on magnetic resonance angiography and venography. This patent describes techniques and systems for non-contrast enhanced magnetic resonance angiography and venography (MRAV). Within one cardiac cycle of a subject, a single shot acquisition of non-suppressed arterial MR signals and a single shot acquisition of non-suppressed venous MR signals are employed. Radio frequency (RF) saturation pulses may be applied to one or more slabs to suppress MR signals indicative of venous blood flowing into the arterial imaging slice and vice versa. The RF saturation pulses and the single shot acquisitions are timed to ensure that data is acquired during steady state inflow of blood into the respective imaging slice. This method allows for the acquisition of k-space data from arterial specific and venous specific imaging slices occurring within a single cardiac cycle.

Another significant patent involves a method for separating chemical species in magnetic resonance imaging. This method includes obtaining an MRI gradient echo train of at least three echo data sets at differing phase angles. It produces a plurality of phase error maps among the echo data sets and images at least three distinct chemical species based on these maps.
