Validation of three deformable image registration algorithms for the thorax
Deformable image registration (DIR) has been proposed for lung ventilation calculation using 4D CT. Spatial accuracy of DIR can be evaluated using expert landmark correspondences. Additionally, image differences between the deformed and the target images give a degree of accuracy of DIR algorithms for the same image modality registration. DIR of the normal end-expiration (50%), end-inspiration ...
متن کاملAutomatic Rigid and Deformable Medical Image Registration
Advanced imaging techniques have been widely used to study the anatomical structure and functional metabolism in medical and clinical applications. Images are acquired from a variety of scanners (CT/MR/PET/SPECT/Ultrasound), which provide physicians with complementary information to diagnose and detect specific regions of a patient. However, due to the different modalities and imaging orientati...
متن کاملPerformance validation of deformable image registration in the pelvic region
Patients undergoing radiotherapy will inevitably show anatomical changes during the course of treatment. These can be weight loss, tumour shrinkage, and organ motion or filling changes. For advanced and adaptive radiotherapy (ART) information about anatomical changes must be extracted from repeated images in order to be able to evaluate and manage these changes. Deformable image registration (D...
متن کاملEvaluation of various deformable image registration algorithms for thoracic images
We evaluated the accuracy of one commercially available and three publicly available deformable image registration (DIR) algorithms for thoracic four-dimensional (4D) computed tomography (CT) images. Five patients with esophagus cancer were studied. Datasets of the five patients were provided by DIR-lab (dir-lab.com) and consisted of thoracic 4D CT images and a coordinate list of anatomical lan...
متن کاملFirst Steps Toward the Automatic Registration of Deformable Scans
Three-dimensional registration is the process of aligning scans of different incomplete views of an object such that their corresponding regions agree in space and time. It is used to build digital complete models from partial acquisitions of real-world objects which typically contain noise, outliers, and acquisition holes due to occlusions and hardware limitations. For non-rigid models, such a...
