Purpose: To simulate exposure (e.g., during interventional procedures) of a worker close to an operating MR scanner by calculating electric fields and current density within an anatomically realistic body model due to a z-gradient coil and to compare results with safety guidelines and European Directive 2004/40/EC.

- The study aimed to combine a high intensity focused ultrasound (HIFU) transducer with an MRI receiver coil to enhance thermal treatment for localized pelvic lesions.
- A specially designed probe was created to enable effective acoustic contact and MR compatibility, improving the signal-to-noise ratio (SNR) significantly with modifications to the transducer surfaces.
- Results demonstrated improved imaging quality and phase detection in MR images at subtherapeutic ultrasound levels, facilitating more precise monitoring during treatment.
