However\, mi croMRI systems cannot resolve cells or compete with optical techniques req uired for pathology and personalized medicine applications. Point-of-use h yperpolarization systems can provide both enhanced signal and contrast ena bling microMRI of small samples such as tumor biopsies and patient derived organoids used for\ntherapeutic evaluation.\nHere\, I present the develop ment of a novel table-top microMRI system that uses integrated point-of-us e solid-state water-proton hyperpolarization systems that rely on spintron ic concepts. The system operates at 135 mT with the nuclear magnetic reson ance (NMR) and ferromagnetic resonance (FMR)-based hyperpolarization syste ms running at ~6 MHz and ~10 GHz\, respectively. The hyperpolarizer operat es at room temperature and low field and is much smaller and simpler than other existing hyperpolarization systems. The mode structure of the FMR fi lm can be complex and needs to be understood to optimize spin transfer. I will discuss spin transport and spin-electrochemistry of ferromagnetic fil ms interacting with proton spins in biologic solutions. The surface spin c hemistry and transport is complex and the essential component of this tech nology. I will also discuss the design of micromagnets\, compact gradients \, FPGA based console\, and compact microwave systems which are required t o enable the fabrication of a low-cost small footprint table-top MRI.\n\nC o-sponsored by: UCCS\n\nSpeaker(s): Stephen Russek\, \n\nRoom: A204\, Bldg : Osborne Center for Science and Engineering\, 1420 Austin Bluffs Pkwy\, C olorado Springs\, Colorado\, United States\, 80918\, Virtual: https://even ts.vtools.ieee.org/m/313830 LOCATION:Room: A204\, Bldg: Osborne Center for Science and Engineering\, 14 20 Austin Bluffs Pkwy\, Colorado Springs\, Colorado\, United States\, 8091 8\, Virtual: https://events.vtools.ieee.org/m/313830 ORGANIZER:dbozhko@uccs.edu SEQUENCE:4 SUMMARY:Table Top microMRI for Cell Imaging URL;VALUE=URI:https://events.vtools.ieee.org/m/313830 X-ALT-DESC:Description: <br /><p>Current microMRI uses large superconductin g magnets (&gt\; 7T) and can obtain a resolution of approximately 2 to 20 micrometers.
