A Multi-Frequency Approach to Increase the Native Resolution of Ultrasound Images
(IEEE, 2012)
In ultrasound (US), a natural competition exists between the resolution of the image and the depth-of-field (DOF) into the medium, competition which is difficult to overcome with current US probe. Using large bandwidth ...
Robust elastic 2D/3D geometric graph matching
(SPIE, 2012)
We present an algorithm for geometric matching of graphs embedded in 2D or 3D space. It is applicable for registering any graph-like structures appearing in biomedical images, such as blood vessels, pulmonary bronchi, nerve ...
Non-Rigid Graph Registration using Active Testing Search
(2014)
We present a new approach for matching sets of branching curvilinear structures that form graphs embedded in R2 or R3 and may be subject to deformations. Unlike earlier methods, ours does not rely on local appearance ...
Spatio-Temporal Motion Estimation for Respiratory-Correlated Imaging of the Lungs
(American Association of Physicists in Medicine, 2011)
Purpose: Four-dimensional computed tomography (4D CT) can provide patient-specific motion information for radiotherapy planning and delivery. Motion estimation in 4D CT is challenging due to the reduced image quality and ...
Line Filtering for Surgical Tool Localization in 3D Ultrasound Images
(Elsevier, 2013)
We present a method for automatic surgical tool localization in 3D ultrasound images based on line ltering, voxel classi cation and model tting. A possible application is to provide assistance for biopsy needle or ...
