Virtual cutting in medical data.
In this paper we present a method for virtual 3D cutting operations in 3D tomographic data. When cutting interactively the user specifies a series of 3D cutting points and corresponding cut depths on the surface of the object. Each pair of succeeding cutting points then defines a freeform shape of the incision. A 3D meshing algorithm constructs a Finite Element mesh formed by tetrahedrons, representing the surgical intervention.
