Analysis of human soft tissue motion and deformation is vital in diverse applications from constitutive modelling in biomechanics to the study of bowel motility. Post-processing Magnetic Resonance Imaging (MRI) to derive soft tissue deformation challenging and requires validation. For this study a novel MRI sequence, based on SPAtial Modulation of the Magnetization (SPAMM) designed for real-time measurement of non-periodic movements was evaluated for its ability to measure 3D soft tissue deformation using marker tracking in a silicone gel phantom. The mean error of the SPAMM based non-invasive deformation measurement technique was found to be 0.75mm.
