Portable Magnetic Resonance Imaging (MRI) systems are revolutionizing medical imaging by breaking free from the confines of dedicated rooms. These point-of-care (POC) MRI machines are compact and designed for imaging in diverse settings such as emergency rooms, ambulances, rural clinics, and field hospitals. Unlike traditional MRI systems with large magnets ranging from 1.5T to 3T, POC MRIs, exemplified by Hyperfine's new machine, feature a much smaller 0.064T magnet.
While ensuring portability, POC MRI machines must still deliver accurate, clear images safely. Hyperfine achieves this by incorporating non-magnetic capacitors, especially trimmer capacitors, to precisely control the radio frequency coil's resonant frequency and impedance. This control determines the machine's sensitivity to RF pulses and signals. Explore the types of non-magnetic surface-mount device (SMD) capacitors, including trimmer capacitors, that are crucial for maintaining reliability and optimal performance in POC MRI machines.
