Variational image registration using inhomogeneous regularization [PDF]

open access: yes, 2014
We present a generalization of the convolution basedvariational image registration approach, in which differentregularizers can be implemented by conveniently exchangingthe convolution kernel, even if it is nonseparableor nonstationary.

On the consistency of Fréchet means in deformable models for curve and image analysis [PDF]

open access: yes, 2010
A new class of statistical deformable models is introduced to study high-dimensional curves or images. In addition to the standard measurement error term, these deformable models include an extra error term modeling the individual variations in intensity

Preliminary Feasibility Study of Imaging Registration Between Supine and Prone Breast CT in Breast Cancer Radiotherapy Using Residual Recursive Cascaded Networks

open access: yesIEEE Access, 2021
Breast cancer is one of the most common malignancies in women. The prone position in Partial Breast Irradiation (PBI) can better protect the heart and lung during radiotherapy. Supine position is used for CT imaging during treatment planning. The posture

Deformable image registration of follow-up breast magnetic resonance images

open access: yes, 2022
S.13-24A novel method for the deformable image registration of follow-up breast magnetic resonance (MR) images is proposed, aimed at an automatic synchronization of temporal images.

Registration of histopathology to magnetic resonance imaging of prostate cancer

open access: yesPhysics and Imaging in Radiation Oncology, 2021
Background and purpose: The diagnostic accuracy of new imaging techniques requires validation, preferably by histopathological verification. The aim of this study was to develop and present a registration procedure between histopathology and in-vivo ...

INSPIRE: Intensity and spatial information-based deformable image registration.

open access: yesPLoS ONE, 2023
We present INSPIRE, a top-performing general-purpose method for deformable image registration. INSPIRE brings distance measures which combine intensity and spatial information into an elastic B-splines-based transformation model and incorporates an ...

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.

Multi-shape Registration with Constrained Deformations

open access: yes, 2021
Based on a Sub-Riemannian framework, deformation modules provide a way of building large diffeomorphic deformations satisfying a given geometrical structure. This allows to incorporate prior knowledge about object deformations into the model as a means of regularisation [10].

Deformable Ultrasound Registration without Reconstruction [PDF]

open access: yes, 2008
Ultrasound (US) imaging is often proposed as an interoperative imaging modality. This use nearly always requires that the collected data be registered to preoperative data of another modality. Existing intensity-based registration approaches all begin by reconstructing a 3D US volume from the collected 2D slices. We propose to directly register the set
