Latest Patents

Leigh Johnston holds a patent for an "Asymmetric RF pulse for a magnetic resonance imaging system." This invention involves constructing an asymmetric RF pulse for an MRI system. The process begins by determining a first RF amplitude for a first part of a time interval. An RF amplitude curve, which depends on at least one RF curve parameter, is then received. A combined RF amplitude curve for the time interval is created by merging the first RF amplitude with the RF amplitude curve for a subsequent part of the time interval. The combined RF amplitude curve is optimized using a loss function that includes an energy loss term, which is based on the pulse energy of the combined RF amplitude curve. The optimization process utilizes the RF curve parameter as a variable, resulting in a refined combined amplitude of the asymmetric RF pulse.
