Volumetric Non-rigid Registration via Thin-plate Spline Model
Registration and warping are essential steps in volumetric data fusion.Medical images are of major parts in diagnosing and treatment and actually are considered a total evaluation of work.In resent years medicines have been using diagnosing devices contain computers as a complementary in detecting harms,evaluating the amount of harm deciding the way of treatment.By quick developing in construction of three dimensional medical imaging devices,high resolution modalities could be used to produce lots of images.This issue is crucial specially in case of medical imaging like Ultrasound,CT and MRI which helps medicines in diagnosing,treatment and investigations.In radiation therapy these information includes surface texture,extracting specified object area in image,and detecting of tumor which can increase the power of medical doctor diagnosing power and usage of image processing techniques will become important in these area.Finding the exact location of target with enough magnification is one of the primary needs in effective radiation therapy.Results show that a Thin Plate Spline is a sufficient model for a volumetric non-rigid registration.The technique is evaluated by mapping of a sphere to a cube and then on a medical object.Experimental result declares that the employed technique is robust in the presence of the noise,changing the number of control points and works effectively in different object resolutions.
