Latest Patents

One of Hoult's latest patents is titled "Detection of ferromagnetic objects approaching a magnet." This innovative apparatus is designed to detect potentially dangerous ferromagnetic objects that a person may inadvertently carry while approaching the magnet of a magnetic resonance imaging system. The device utilizes the fringe field of the magnet and includes guide members that define a safe path for individuals to follow. The path is generally parallel to the magnetic field, and it features at least one sense coil, with typically two sets of sense coils positioned on either side of the path. The movement of any ferromagnetic object within the magnet's field generates a voltage in the sense coil, ensuring safety during imaging procedures.

Another notable patent is the "Method of effecting nuclear magnetic resonance experiments using Cartesian feedback." This method employs Cartesian electronic feedback to significantly reduce the adverse effects of sample-mediated and direct interactions between coils in an array of transmitting and/or receiving coils during nuclear magnetic resonance experiments. The feedback mechanism maintains constant relationships between input transmitter voltage and magnetic resonance flip angle, as well as between transverse nuclear magnetization and the strength of the free induction decay signal presented by a receiver for analysis, regardless of variations in sample electrical conductivity.
