Research on Visualization of Three-dimensional Surface in Tumor Magnetic Inductive Thermotherapy Plan System

摘要

Because that magnetic inductive thermotherapy requires to implant magnetic inductive media in tumor area with heating under the stimulation of external alternating magnetic field and is a clinical interventional treatment, so it is very important and essential for a doctor to make a reasonable treatment plan in magnetic inductive clinical treatment diagnosis and preoperative plan. The intuitional three-dimensional virtual patient information plays a vital function in making a plan. The research takes advantage of computer graphics algorithm to study the drawing of three-dimensional visual surface of medical image, extracts and launches a study on contour surface through voxel model, contour surface model and MC (Marching Cubes) algorithm and achieves the visual process of three-dimensional surface drawing of medical CT (Computed Tomography) sequence images, which can clearly build well-defined and intuitive virtual focus model and improve the quality and accuracy of thermotherapy plan.
