Abstract：Magnetic induction hyperthermia treatment planning system (MHTPS) should provide a more intuitive three-dimen-sional attribute to doctor to develop the most dominant heat treatment plan.Traditional method need to draw all slices contained target manually, then start three dimensional reconstruction.It takes a huge amount of time and unable to meet high efficiency requirements in clinical application.To improve the efficiency of manual segmentations,we systematically studied the numerical methods to segment tissues and organs in hyperthermia planning and conducted a semi-manual minimum energy segmentation method based on the thin plate spline in multi-directional slices.Finally, the experimental results show that this method can describe the two-dimensional contour and three-dimensional model of human tissue organs and tumors well,and solve the problem of the optimal shape of the 3D treatment target area in the magnetic induction hyperthermia treatment planning system,moreover, the efficiency of traditional manual segmentation method is improved and can be used to treatment planning system and reduce the workload of doctors and physiologists.
