Latest Patents

Iulius Dragonu's latest patents include a method for subject-specific optimization of a multi-band RF pulse. This method focuses on optimizing an RF pulse that is multi-band, utilizing a spokes RF pulse that consists of a train of sub-pulses. The process involves using a starting k-space position as the current k-space position and performing calculations for each slice to be excited by the RF pulse. The calculations include determining a sub-pulse based on the current k-space position and calculating an expected magnetization after that sub-pulse. Additionally, an inverse Fourier transform of the difference between the expected magnetization and a target magnetization is calculated. The optimal k-space position for the next spoke is then determined for each slice, leading to the creation of a multi-band RF pulse based on these positions.

Another significant patent by Dragonu is related to acquiring MRI data from an MRI scan of an object. This method involves generating a series of excitation sequences, which include generating an excitation pulse, an imaging magnetic field gradient, and a spoiler magnetic field gradient. MRI data is collected during the generation of the spoiler magnetic field gradients, ensuring that the same k-space trajectory is traversed during each excitation sequence.
