Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Speckle tracking echocardiography (STE) is now widely used  for measuring strain, deformations, and motion in cardiology. STE involves three successive steps:  acquisition of individual frames, speckle detection, and image registration using speckles as landmarks. This work  proposes to avoid explicit detection and registration by  representing dynamic ultrasound images as sparse  collections of moving Gaussian elements in the continuous  joint space-time space. Individual speckles or local clusters of speckles are approximated by a single multivariate Gaussian kernel with associated linear#R##N#trajectory over a short time span. A hierarchical tree-structured model is fitted to sampled input data such that predicted image estimates can be retrieved by regression after reconstruction, allowing a (bias-variance) trade-off beten model complexity and image resolution.  The inverse image reconstruction problem is solved with an  online Bayesian statistical estimation algorithm. Experiments on clinical data could estimate subtle sub-pixel accurate motion that is difficult to capture with frame-to-frame elastic image registration techniques.
