Latest Patents

One of Arakawa's latest inventions is the inherently de-coupled sandwiched solenoidal array coil (SSAC). This innovative coil is designed for receiving NMR radio frequency (RF) signals in horizontal and vertical-field MRI systems. The SSAC comprises two coaxial RF receive coils, where the first coil contains two solenoidal sections that are separated along a common axis. Such a design allows the individual sections to be connected in series while creating opposing magnetic fields to achieve a null region between them. This arrangement leads to electromagnetic de-coupling of the receive coils, maintaining their sensitivity to NMR signals while also allowing flexibility in field-of-view (FOV) selection, thereby preventing image fold-over issues during data acquisition. Additionally, several alternative embodiments are proposed within the patent, showcasing configurations for optimized breast imaging.
