Title: Innovations in MRI Technology by John W. Missal
Introduction
John W. Missal is a notable inventor based in Willoughby, Ohio, recognized for his contributions to magnetic resonance imaging (MRI) technology. With a focus on enhancing the capabilities of MRI systems, he has developed innovative solutions that improve both speed and image quality in medical imaging.
Latest Patents
One of his significant patents is for a multi-mode receiver assembly for MRI systems. This invention allows the MRI apparatus to operate in both quadrature combination mode and phased array mode. The multi-mode receiver assembly includes a receiver coil assembly that comprises a first RF coil assembly and a second RF coil assembly. A signal combining circuit, which features a switch means, performs the functions of combining and splitting magnetic resonance signals received by the two coil assemblies. The application of a DC bias potential to the switch means enables the assembly to switch into quadrature combination mode, where the received signals are phase-shifted and combined into quadrature and anti-quadrature signals. Conversely, the absence of a DC bias potential switches the assembly into phased array mode, allowing for individual processing of the signals. This dual capability enhances the efficiency and quality of MRI examinations.
