Approach

Multi-Scale

— Improves time efficiency

• Limits the number of nodes considered at one time

• Based on the notion that a point force has a limited region

of influence

An m-rep figure shown at three different scales

Finite Element Analysis

— Calculates deformation of meshed objects based on mathematical model of tissue mechanics

Medial Models

— Represents solid object shape & topology, and guides mesh generation

Force Generation

— Drives finite element computations, and can be derived from

1) a known force, as from the ultrasound probe or

2) image data where deformation is apparent
