Interslice coding of magnetic resonance images using deformable triangular patches

We present a new inter-frame coding for medical images, in particular magnetic resonance (MR) images. Until now, attempts in using inter-frame redundancies for coding MR images have been unsuccessful. We contend that the main reason for this is twofold: bad inter-frame estimation models and ignoring the thermal noise inherent in MRI. Our inter-frame model is a continuous affine mapping based on (and optimized by) deforming triangles. The inherent noise of MRI is dealt with by using a median filter within the estimation loop. Simulations demonstrate the viability of this algorithm.<<ETX>>
