The manufacturing of intravascular imaging coils poses several challenges. Due to their size, it can be difficult to incorporate local matching networks and signal amplifiers. This study investigates tuning and amplification strategies for intravascular coils and to assess the signal-to-noise benefits of incorporating a matching network and/or miniature amplifier into catheter-based intravascular imaging devices at various locations in the signal chain. Results suggest that the use of a LNA close to the receiving coil allows for miniature coax cables to be used despite being noisy. Therefore, designing devices for intravascular applications capable of generating high-SNR images becomes much more feasible.
