Abstract:The goal of this thesis is to determine the feasibility of an MRI compatible ultrasound transducer. Combining the capabilities ofMRI and ultrasound allows us to create a superior imaging method which has a fast frame rate and a high quality image. A literature study was combined with prototype testing to determine which materials were suitable for use in an MRI compatible ultrasound transducer. The presence of conductive materials does not seem to be a direct problem for the safety of the patient and the imaging quality, while ferromagnetic metals should be avoided. Image degradation occurred when a signal was applied to the prototype. Despite expectations set by the literature study, aluminium did not provide sufficient shielding, as an increase in zipper artefacts could be seen in the MRI image. This study showed that it should possible to make an MRI compatible ultrasound transducer if shielding is taken into account.
