With a total of 6 patents, his work focuses on innovative methods and systems that enhance the understanding of brain function and structure.

Latest Patents

Yarnykh's latest patents include groundbreaking technologies such as "Methods and systems for quantitative brain assessment." This patent describes systems and methods for measuring macromolecular proton fraction in a subject. A nuclear magnetic resonance apparatus applies a magnetic field to a body region on the subject, and radiofrequency modes are applied to the body region as well. Each radiofrequency mode delivers a plurality of radiofrequency pulses separated by time delays, wherein at least one of the radiofrequency modes causes suppression of signal components from unwanted tissue. Additionally, at least one of the radiofrequency modes facilitates magnetization exchange between water and macromolecules in tissues in the body region. The amplitudes corresponding to magnetic signals received from the body region are measured, allowing for the calculation of macromolecular proton fraction based on these amplitudes.

Another notable patent is the "Motion-sensitized driven equilibrium blood-suppression sequence for vessel wall imaging." This patent presents an improved motion-sensitization driven equilibrium (iMSDE) sequence based upon an MLEV-4 sequence for black-blood vessel wall imaging. The iMSDE sequence includes a group of four radio frequency (RF) pulses, as well as additional magnetic gradient pulses that are not included in the conventional MSDE sequence. Computer simulations indicate that this new pulse sequence is substantially more immune to local B1 inhomogeneity than conventional sequences. In vivo experiments have demonstrated significant signal improvement at high first-order moments (m) conditions compared to the traditional MSDE sequence.
