UBone3D: Physics-Rectified Conditional Flow Matching for Anatomical 3D Shape Completion from Ultrasound
Weiying Chen, Yuchong Gao, Siyuan Li +3
Three-dimensional ultrasound (US) is a safe, radiation-free complementary modality to CT and X-rays for longitudinal monitoring, yet its segmentation-derived partial point clouds a…
RoCoSDF: Row-Column Scanned Neural Signed Distance Fields for Freehand 3D Ultrasound Imaging Shape Reconstruction
Hongbo Chen, Yuchong Gao, Shuhang Zhang +3
The reconstruction of high-quality shape geometry is crucial for developing freehand 3D ultrasound imaging. However, the shape reconstruction of multi-view ultrasound data remains…
Neural Implicit Surface Reconstruction of Freehand 3D Ultrasound Volume with Geometric Constraints
Hongbo Chen, Logiraj Kumaralingam, Shuhang Zhang +9
Three-dimensional (3D) freehand ultrasound (US) is a widely used imaging modality that allows non-invasive imaging of medical anatomy without radiation exposure. Surface reconstruc…
Automatic bony structure segmentation and curvature estimation on ultrasound cervical spine images -- a feasibility study
Songhan Ge, Haoyuan Tian, Wei Zhang +1
The loss of cervical lordosis is a common degenerative disorder known to be associated with abnormal spinal alignment. In recent years, ultrasound (US) imaging has been widely appl…
