Ultrasound (US) and magnetic resonance (MR) are two well-established imaging modalities with largely complementary contrast mechanisms. We propose and experimentally evaluate the feasibility of a fundamentally new tool; miniaturized two-dimensional (2-D) US collocated with a one-dimensional (1-D) single-sided MR system for bimodal imaging in portable or wearable form factors. The proposed system will be capable of scheduling both measurements in real-time, thus enabling closed-loop operation in which the output of one sensor is used to optimize the operation of the other. We study the feasibility of such a system and show preliminary experimental results obtained by combining a commercial US imaging system with a custom single-sided planar MR sensor.
