Abstract
A simulation is performed by assigning tissue type properties to voxels of a medical image and manipulating the voxels based on the assigned tissue type properties and an input that prompts voxel manipulation. Voxels may also be created and eliminated in response to the input. Tissue type properties may include elasticity, ductility, hardness, density, and thermal conductivity. Manipulation may include changing at least one of voxel size, location, orientation, shape, color, grayscale, and tissue type property value. The input may include insertion of a virtual volume-subtending surgical or anatomic object. Simulations may include virtual motion, deformation of tissue, and radiological dissection for pre-operative planning.
