Multiscale Centerline Detection [PDF]

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2016
Finding the centerline and estimating the radius of linear structures is a critical first step in many applications, ranging from road delineation in 2D aerial images to modeling blood vessels, lung bronchi, and dendritic arbors in 3D biomedical image stacks. Existing techniques rely either on filters designed to respond to ideal cylindrical structures

Determination of intramedullary nail based on centerline adaptive registration

Frontiers in Bioengineering and Biotechnology, 2023
Objective: Internal fixation with intramedullary nails is a gold standard for the treatment of femoral shaft fractures. However, both the mismatch between intramedullary nails and the medullary cavity and inaccurate positioning of entry points will lead ...
