Fast Musculoskeletal Registration Based on Shape Matching

Abstract: Abstract. This paper presents a new method for computing elastic and plastic deformations in the context of discrete deformable model-based registration. Internal forces are estimated by averaging local transforms between reference and current particle positions. Our technique can accommodate large non-linear deformations, and is unconditionally stable. Moreover, it is simple to implement and versatile. We show how to tune model stiffness and computational cost, which is important for efficient registration, a… Show more

“…Notably, the results were surface models representing real time contour deformations. In [6], a general framework aimed at biomedical engineering for macroscopic 4D-modeling of skeletal muscles is given, especially for the human gastrocnemius and the biceps brachii muscle.…”

“…Somphone et al transformed their binary template, subject to conformity constraints between local patches [25]. In a different approach, Gilles et al used explicit shape representation of the template to segment the musculoskeletal structures out of MR images [26]. The mesh deformation was regularized based on an expanded version of a computer animation technique called shape matching [27].…”

“…target image in an initial state and deformed by minimizing an objective function composed of two terms: a data-term -attracting the surface to detected image contours -and a regularization term, ensuring the surface remains realistically smooth or similar enough to a reference surface (as in [7]). In [4], prior knowledge on the shape of one muscle is further enforced by imposing the model to reside in a hierarchical shape space built via diffusion wavelets decomposition on training examples.…”
