Colon diagnosis using CT images of supine and prone positions is time-consuming task because a radiologist has to control viewing fields of virtual colonoscopic (VC) views individually. We propose a method to display VC views of corresponding areas of the colons in the two positions. Viewpoints of VC views in the two positions are obtained by a point interpolation based on the result of the supine-prone correspondence finding. Up-directions of VC views defined based on body orientations of a patient. We generated synchronized VC views of the two positions using the proposed method. Positional difference of the viewpoints between the two positions was 5.03 [mm]. The method can synchronize viewpoints of the supine and prone positions without significant error.
