Incorporation of a variational registration method into a spectroscopy tool
نویسندگان
چکیده
This work describes the incorporation of a variational image registration algorithm into an interactive medical tool to support clinical decision about treatment of brain pathologies. Through the combination of anatomical (Magnetic Resonance Images, MRI), functional (Positron Emission Tomography, PET) and molecular images (Chemical Shift Imaging, CSI) clinicians can determine the best therapeutic strategy in every case. First, MRI images and CSI are co-registered and analysed in order to create colour maps related with the concentration of metabolites in the brain. Then, PET and MRI are also registered since it allows knowing the metabolic functionality of the brain. The improvement of the Correlation Ratio (CR), the Structural SIMilarity (SSIM) and the Mutual Information (MI) shows the performance of the variational registration method which is at least two times faster than other approaches in the spatial domain. The goal of this tool is to provide surgeons as much information as possible to perform biopsies and/or surgeries.

متن کاملConsistent multi-modal non-rigid registration based on a variational approach
In this paper, a novel variational approach for multi-modal image registration based on consistent non-rigid transforms is proposed. The forward and backward transforms are computed in a variational framework simultaneously. A consistency energy is added into the variational registration framework and an iterative method assures that the forward and backward transforms are close approximate inv...

For the problem of multimodal image registration, an optimal control approach is presented. The geometrical information of the images will be transformed into weighted edge sketches, for which a linear-elastic or hyperelastic registration will be performed. For the numerical solution of this problem, we provide a direct method based on discretization methods and large-scale optimization techniq...
متن کاملCombining Automatic Landmark Detection and Variational Methods for Lung CT Registration
This paper proposes a novel method for image registration of lung CT scans. Our approach consists of a procedure for automatically establishing landmark correspondences in lung CT scan pairs and an elaborate variational image registration scheme. The landmark information is incorporated into the registration scheme as pre-registration using the landmark-based Thin-Plate-Spline (TPS) method. The...
