Current SPAMM methods typically construct data from many repeated motion cycles. However discomfort and health issues may preclude a large number of repetitions. The current study presents the validation of a novel fast SPAMM sequence for the measurement of dynamic 3D soft tissue deformation following just 3 repeated motion cycles. The techniques were validated using marker tracking in a silicone gel phantom and demonstrated a mean displacement difference of 0.07mm (standard deviation 0.6mm). Since only 3 motion cycles are required the presented methods are the fastest currently available for the dynamic measurement of non-linear 3D soft tissue deformation.
