Estimation of Hounsfield unit conversion parameters for pelvic CT images [PDF]
Australasian Physical & Engineering Sciences in Medicine, 2018 Linear scaling is used to convert raw computed tomography (CT) pixel values into Hounsfield units corresponding to different tissue values. Analysis of a benchmarking study, presented here, where the same CT scan was imported into and then exported from multiple radiotherapy treatment planning systems, found inconsistencies in HU scaling parameter ...

Bronchoscope Tip Localization With Learned Airway Constraints and an Open Source Simulator
Advanced Intelligent Systems, EarlyView.BronchoLoc addresses feature‐poor bronchoscopic imaging by combining monocular video with a preoperative CT graph to estimate 3D camera location. A local tracker identifies candidate branches, while a sequence‐aware global module refines the trajectory. Demonstrating sub‐centimeter accuracy across synthetic and phantom datasets, this framework advances
