A crossbar switch matrix can be flexibly connected to any input and output paths via RF switches. However, this type of matrix creates open-stubs in the RF lines. Since the RF wavelength becomes shorter as the magnetic field increases, signal loss due to impedance variations in RF pathways becomes severe, thus degrading image quality. In this study, we propose an advanced compensation method and verify its performance in ultra-high field MRI with single and multi-channel array coils.
