A fast method in reconstruction 3D computed tomography medical images

Computed tomography greatly improves the image information available to surgeons and is quickly becoming one of the most important methods to check for defects inside the patients. However, doctors must check these CT slices and again to find the exact position for the patients. This is not only of waste time but also highly inefficient. This paper presents a fast process to reconstruct 3D surfaces from 2D CT scanned data. Based on the geometric models, a series of 2D CT image slices can be read and transformed into profiles. A 3D B-Spline patch model is then generated. After that it can also be converted to VRML format for virtual surgical application. An actual rapid prototyping model is then made for checking the design process. This actual model allows doctors or patients to observe the CT slices in 3D. This system decreases training time and provides references for medical image research.
