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.
