Sensor Instrumentation For Micro Magnetic Resonance Imaging Towards Tissue Biopsies

the demand on Magnetic Resonance Imaging (MRI) in hospital is towards high resolution with possible lower magnetic field. The method for micro imaging on tiny samples in submillimeter level has been researched in the Radio Frequency (RF) and pulsed-DC scope for this publication. A set of planar coils with middle-high field gradients was designed to image dandelion slice in the size of 1.5 mm. A group of Radio Frequency electronics modules was utilized and characterized as transceiver. Considering the isolation is not efficient according to current transceiver probe & associated amplification scheme, further an active RF switch would be used. The current gradient coils integrated on the probe insertion have the ability to carry 0.1 mm resolution experiments without cooling. In next steps A biopsy of Caenorhabditis elegans would also be investigated for micro Magnetic Resonance Imaging with the probe proposed.
