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.
