title: The correction of MR images distortion with phantom studies.
abstract: In the field of Image Guided surgery, Geometrical accuracy of images acquired from CT and MR is an essential prerequisite for good registration process. In this paper, we present the experiment with MR phantom. We visualize the distortion of MR images in 3-D shape and modify it by surface fitting algorithm using the control Point.
