Benchmarking and performance evaluation of a novel deformable image registration software for radiotherapy CT images

Technical Innovations & Patient Support in Radiation Oncology
Purpose: We evaluated and benchmarked a novel deformable image registration (DIR) software functionality (DirOne, Cosylab d.d., Ljubljana, Slovenia) by comparing it to two commercial systems, MIM and VelocityAI, following AAPM task group 132 (TG-132 ...

Adversarial Deformation Regularization for Training Image Registration Neural Networks [PDF]

, 2018
We describe an adversarial learning approach to constrain convolutional neural network training for image registration, replacing heuristic smoothness measures of displacement fields often used in these tasks.

Fast Predictive Image Registration

, 2016
We present a method to predict image deformations based on patch-wise image appearance. Specifically, we design a patch-based deep encoder-decoder network which learns the pixel/voxel-wise mapping between image appearance and registration parameters. Our

Contour Propagation for Radiotherapy Treatment Planning Using Nonrigid Registration and Parameter Optimization: Case Studies in Liver and Breast Cancer

Applied Sciences, 2022
Radiotherapy treatments are carried out using computerized axial tomography. In radiation therapy planning, the radiation oncologist must do a manual segmentation of volumes of interest to delineate the organs that should be irradiated.

Image Registration Techniques: A Survey

, 2017
Image Registration is the process of aligning two or more images of the same scene with reference to a particular image. The images are captured from various sensors at different times and at multiple view-points.

A Robust Registration Algorithm for Image-Guided Surgical Robot

IEEE Access, 2018
The aim of this paper is to propose a robust registration algorithm to reduce the impact of the marker-recognition error on image-to-physical registration in the robot-assisted cranio and maxillofacial (CMF) surgery. Since the image-guided technology has
