Surface MRI Using a Rastered Backprojection
Lucero T, Bright A, Hornak J, Bray C
Magnetic resonance imaging (MRI) is typically performed by placing the imaged object within a spatially homogeneous magnetic and radio frequency (RF) fields. This convention restricts MRI to system geometries which surround the imaged object with a magnet and RF coil. Many applications could benefit from a surface MRI device where magnet and RF coil are adjacent to the imaged object. We have developed a proof-of-concept surface MRI system which uses an inhomogeneous magnetic field, RF surface coil, and unique reconstruction method to produce tomographic images. Details of our unique system and reconstruction technique, along with phantom images, are presented.
