FONAR offers a wide range of Solenoid-, Planar- and Quadrature-Coils to use in the Upright™ MRI. FONAR has several in-house teams of high-level scientists and engineers devoted to improving existing receiver coil designs and introducing new ones.

FONAR’s first receiver coils, or surface coils, were solenoid receiver coils. These coils are basically wrapped around the region of interest. The solenoid receiver coil has been and continues to be a perfect match for FONAR scanners. It is a fundamental fact of physics that optimal Signal-to-Noise Ratios (SNR) are achieved when the axis of the receiver coil is perpendicular to the direction of the scanner’s magnetic field.

With superconductive MRI scanners, the horizontal magnetic field would be parallel, rather than perpendicular, to the solenoid coil axis. Therefore these scanners cannot capitalize on the SNR advantage of the solenoid design are forced to use less efficient receiver coil designs instead.

The unique transaxial horizontal magnetic field of the Upright™ MRI makes it the ONLY Open MRI system that can use flat planar coils. The advantage of planar coils is that they can be placed close to the targeted anatomy, which results in high Signal-to-Noise Ratios (SNR) and, therefore, excellent images.
