Synopsis

Cardiovascular MRI at the ultra-high-field is an emerging modality promising a significant increase of the spatial resolution and physical sensitivity of routine cardiac imaging. Pig models play an important role in the establishment and translation of 7T cMRI to humans. The prerequisite for high-quality 7T cMRI data in pigs is dedicated transceiver arrays adapted to the shape of the pig’s thorax. We validated the proof-of-concept of the transceiver pTX cardiac array with adjustable parabolic shape housing for longitudinal studies with pigs. The stability of the transmit and receive characteristics by shape adjustments are tested in-silico and in phantom measurements.
