Evaluation of deformable image registration in HDR gynecological brachytherapy
Introduction: In brachytherapy, as in external radiotherapy, image-guidance plays an important role. For GYN treatments it is standard to acquire at least CT images and preferably MR images prior to each treatment and to calculate the dose of the day on each set of images. Then, the dose to the target and to the organs at risk (OAR) is calculated with worst case scenario from I...
متن کاملA Deformable Image Registration Algorithm Using NURBS
Non-rigid image registration is an interesting and challenging research work in medical image processing, computer vision and remote sensing fields. In order to increase the registration accuracy, this paper designs a composite registration algorithm of a rigid transform and free form deformation. Because NURBS (Non-uniform Rational B Spline) with a non-uniform grid has a higher registration pr...
متن کاملDeformable Image Registration using Spring Mass System
The paper describes a novel multi-resolution registration method. It is fast, robust and offers high registration accuracy. The algorithm models deformations using an elastic spring mass system, which contains sparse masses interconnected by springs. The proposed method uses data intensity values to guide deformation with local constraints imposed by interaction of interconnecting springs. More...
متن کاملMjolnir: Deformable Image Registration using Feature Diffusion
Image registration is the process of aligning separate images into a common reference frame so that they can be compared visually or statistically. In order for this alignment to be accurate and correct it is important to identify the correct anatomical correspondences between different subjects. We propose a new approach for a feature-based, inter-subject deformable image registration method u...
متن کاملStrain Measurement Using Deformable Image Registration
The accurate determination of strain in deforming biological tissues is a necessary and important part of experimental investigations in biomechanics. We have developed a method, referred to as Hyperelastic Warping, to combine medical image data with a solid mechanics analysis approach to allow estimation of tissue strains in the absence of detailed information about boundary conditions and in ...
