摘要

In transcranial magnetic resonance-guided focused ultrasound (tcMRgFUS) treatments, the degassed water flowing between the gap of the skull and the focused ultrasound (FUS) transducer was used for acoustic coupling and skull skin cooling. However, the circulating water may affect the magnetic resonance (MR) images, such as introducing uncertain artifacts or reducing signal-to-noise ratio (SNR). Th...
