Abstract

Magnetic resonance microscopy is an advanced type of magnetic resonance imaging (MRI) where the image resolution goes beyond of conventional clinical MRI to image very small tissue samples. The image resolution directly depends on the sensitivity of the detector coil, which is responsible for sensing weak magnetic fields from small samples in an MRI scanner. This paper describes the design of two magnetic field detection coils based on a solenoid and Alderman-Grant shapes. The coils are designed to provide over 90% field homogeneity in a 125 mm3 volume to image a 1 mm IDD tissue punctured sample. The performance of the two coils are evaluated theoretically using electromagnetic simulations, and experimentally in a 7 tesla preclinical MRI scanner.
