Random Walks for Deformable Image Registration [PDF]

open access: yes, 2011
We introduce a novel discrete optimization method for non-rigid image registration based on the random walker algorithm. We discretize the space of deformations and formulate registration using a Gaussian MRF where continuous labels correspond to the probability of a point having a certain discrete deformation.

Progressive 3D biomedical image registration network based on deep self-calibration

open access: yesFrontiers in Neuroinformatics, 2022
Three dimensional deformable image registration (DIR) is a key enabling technique in building digital neuronal atlases of the brain, which can model the local non-linear deformation between a pair of biomedical images and align the anatomical structures ...

Validating Dose Uncertainty Estimates Produced by AUTODIRECT: An Automated Program to Evaluate Deformable Image Registration Accuracy. [PDF]

open access: yes, 2017
Deformable image registration is a powerful tool for mapping information, such as radiation therapy dose calculations, from one computed tomography image to another. However, deformable image registration is susceptible to mapping errors.

Noncoplanar Radiation using Tomotherapy: A Phantom Study

open access: yesTechnology in Cancer Research & Treatment, 2020
Background: There are very few studies on noncoplanar radiation in tomotherapy because deformable image registration is not implemented in the TomoTherapy Planning Station, a treatment planning device used in tomotherapy.

Medical Image Registration Incorporating Deformations. [PDF]

open access: yesProcedings of the British Machine Vision Conference 1995, 1995
Multiple sources of 3D medical image data can be used to construct detailed patient representations. Typically registration is achieved assuming the validity of rigid body transformation. In many applications, and in particular when updating representations used for guidance during surgery and therapeutic interventions, this assumption is inappropriate.

Biomechanical model-based deformable registration of MRI and histopathology for clinical prostatectomy

open access: yesJournal of Pathology Informatics, 2011
A biomechanical model-based deformable image registration incorporating specimen-specific changes in material properties is optimized and evaluated for correlating histology of clinical prostatectomy specimens with in vivo MRI.

Effect of image registration on 3D absorbed dose calculations in 177 Lu-DOTATOC Peptide Receptor Radionuclide Therapy [PDF]

open access: yes, 2018
Peptide receptor radionuclide therapy (PRRT) is an effective MRT (molecular radiotherapy) treatment, which consists of multiple administrations of a radiopharmaceutical labelled with 177Lu or 90Y.

Interactive Multigrid Refinement for Deformable Image Registration [PDF]

open access: yesBioMed Research International, 2013
Deformable image registration is the spatial mapping of corresponding locations between images and can be used for important applications in radiotherapy. Although numerous methods have attempted to register deformable medical images automatically, such as salient-feature-based registration (SFBR), free-form deformation (FFD), and demons, no automatic ...
