Introduction Development of patient specific implantsReconstruction of three dimensional (3D), Bio-CAD models fromcomputer tomography (CT) images are some of the problem that has been emergedbecause of enhanced development of IT and adverse engineering method. Thismodel is for medical image. It is required to make attention on such issues that arebeing faced. Reverse Engineering (RE) and Rapid Prototyping (RP) are few of thesurgical imagery and free form application. The above techniques are effective toformulate anatomic models. This model has different features like symptomatic,therapeutic and rehabilitation medical techniques (Carlesimo, Lombardi andCaltagirone, 2011). The above mentioned Bio-CAD models are effective in their own way formedical practitioners which has number of features like computer-aided surgery,functional modelling of weave, design of orthopaedic device, organism, tissueplatform and free form fictionalisation or bio-manufacturing [1-4]. This model is also very helpful in non- medical techniques where it is effective intreatment. Such application consists for also fir the treatment of traveller safetydesigning and crash investigation [2, 4-7]. For the reconstruction of 3D Bio-CAD models, mass based or isometricbased approachers are considered at large level. Voxel (Volume image) is used inbetter way for the interpretation of CT scan data. This system is used at large inthought commercialism available bio surgical software (Chang and et. al, 2013).Voxel model is depicted by cuboidal or optical device elements which is set as per itstallness, width and extent. It is transferred to stl (stereolithography) format. When it is transformedin this format then it is printed on rapid prototyping system. This format is effectivein high resolution surface and it is for visual image of human anatomy. There aresome of its limitation and restriction as it require large memory, loss of geometricinformation. It is not preferable in model eating. Triangular patterned theory frommarch cube is hard for the production and technology application which is exceptpre-processing [8, 10]. The cited limitation of voxel model is replaced by transferring CT imagemodel into CAD based solid models, that considers isometric based formulation.Representation of CAD based model can be made by boundaries. It envelops in'boundary representation' method. B-Spline curves, Non-Uniform Coherent B-Spline(NURBS) elements are considered to make the boundary surface. This is helpful inproviding some other advantages of taking higher degree continuity. Tangential(C1 ) and Curvature (C2 ) over Positional (C0 ) continuity is in stl data. This is effective method that is beneficial as comparison to volume basedapproach. It is advantageous because of its editable and limited file size. It ensureswater tight surface model. RE (Reverse Engineering) technique is used in better waybecause it comprises of different steps. These stages cover action; pre process forelimination of noise and out liars; generation of partition and theory from pointcloud data [8,9] (Dreher and Schneider, 2010).
