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

Journal 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.

Noncoplanar Radiation using Tomotherapy: A Phantom Study

Technology 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.

DIRBoost - an algorithm for boosting deformable image registration. Application to lung CT intra-subject registration [PDF]

, 2022
S.449-459We introduce a boosting algorithm to improve on existing methods for deformable image registration (DIR). The proposed DIRBoost algorithm is inspired by the theory on hypothesis boosting, well known in the field of machine learning.

Statistical Motion Mask and Sliding Registration [PDF]

, 2018
Accurate registration of images depicting respiratory motion, e.g. 4DCT or 4DMR, can be challenging due to sliding motion that occurs between the chest wall and organs within the pleural sac (lungs, mediastinum, liver).

A GPU-Accelerated Deformable Image Registration Algorithm With Applications to Right Ventricular Segmentation

IEEE Access, 2017
Delineation of the cardiac right ventricle is essential in generating clinical measurements such as ejection fraction and stroke volume. Given manual segmentation on the first frame, one approach to segment right ventricle from all of the magnetic ...
