Thermo-acoustic ultrasound (TAUS) has been shown to be able to detect the peaks in local SAR indicative of RF-induced lead tip heating in an MRI setting. Here, we detail a reproducible TAUS acquisition system consisting entirely of commercially accessible electronics that can interface with an MRI scanner. This system achieves comparable performance to our previously demonstrated acquisition system with lower cost electronics, while also providing additional functionality that could aid in the development of a robust TAUS pre-scan to assess the risk of RF-induced lead tip heating in MRI.
