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.
