The suitability of a compact Samsung ultrasound (US) system for real-time imaging guidance of treatment device positioning inside 1.5T interventional magnetic resonance imaging (iMRI) suite was assessed. The US system was tested in a proposed site-specific configuration. Magnetic displacement forces exerted by the static magnetic field on each of the US system components were estimated at the proposed locations. Image quality of both MRI and US systems with the US system set to different operating modes were evaluated. Results demonstrate that this particular US system is suitable for use in the site-specific configuration at our 1.5T iMRI suite.
