Virtual Prototyping & Bio Manufacturing in Medical by Bopaya Bidanda, Paulo Jorge Bártolo

By Bopaya Bidanda, Paulo Jorge Bártolo

The unique position of RP was once to verify the form and believe of proposal layout, yet recommendations in RP now let for the improvement of subtle clinical units resembling catheters, stents, drug supply structures, syringes and cardio-vascular units, and extra. RP has moved past clinical units, as surgeons now frequently use RP types to brainstorm suggestions for surgical procedures. This ebook offers new makes use of for speedy prototyping in state of the art clinical applications.

It should be noted, however, that bone surgery simulation deals with inhomogeneous materials while virtual sculpting deals with homogeneous materials. The material removal can be achieved by continuously performing Boolean subtraction of the geometric model of the moving tool from the bone model. Galyean and Hughes (1991) introduced the concept of voxel-based sculpting as a method of creating free from 3D shapes by interactively editing a model represented in a voxel raster, and developed a virtual sculpting system with a simple tool.

Two examples of such a system are shown in Fig. 12. This PHANToM has three motors and six encoders to enable 6-DOF motion tracking and 3-DOF force feedback. The GHOST (General Haptics Open Software Toolkit) SDK is a C++ object-oriented software toolkit that enables application developers to interact with the haptic device and create a virtual environment at the object level. GHOST SDK provides a special Fig. 12 Virtual bone surgery with haptic feedback: (a) Chi et al. (2005); (b) Agus et al. (2002) 38 M.
