3D real-time imaging of joints in motion can help us gain valuable insight into joint disorders. The combination of 3D golden-ratio re-ordered cones and multiscale low-rank reconstruction allow for continuous acquisition and high accelerations making 3D real time dynamic imaging of knees possible. We demonstrated the feasibility of this approach to capture patellar motion caused by a quadriceps flexion in 16 slices and with a temporal resolution of ~500ms. Although the resulting images are blurred, this method shows promise.
