Multi-site, Multi-domain Airway Tree Modeling

Jiancheng Yang, Yi Wu, Ying Zhu, Boyu Zhang

Open international challenges are becoming the de facto standard for assessing computer vision and image analysis algorithms. In recent years, new methods have extended the reach of pulmonary airway segmentation that is closer to the limit of image resolut ...

Prediction of Dispersion Rate of Airborne Nanoparticles in a Gas-Liquid Dual-Microchannel Separated by a Porous Membrane: A Numerical Study

Carlotta Guiducci, Zohreh Sheidaei

Recently, there has been increasing attention toward inhaled nanoparticles (NPs) to develop inhalation therapies for diseases associated with the pulmonary system and investigate the toxic effects of hazardous environmental particles on human lung health. ...

Endoscopic Fluorescence Imaging

Blaise Lovisa

Since several decades, the physicians are able to access hollow organs with endoscopic methods, which serve both as diagnostic and surgical means in a wide range of disciplines of the modern medicine (e.g. urology, pneumology, gastroenterology). Unfortunat ...

Endoscopic low coherence interferometry in upper airways

Christian Depeursinge, Florian Lang, Daniel Boss, Yves Delacrétaz

We introduce Endoscopic Low Coherence Interferometry to obtain topology of upper airways through commonly used rigid endoscopes. Quantitative dimensioning of upper airways pathologies is crucial to provide maximum health recovery chances, for example in or ...

Optimized autofluorescence bronchoscopy using additional backscattered red light

Hubert van den Bergh, Georges Wagnières, Tanja Gabrecht

Autofluorescence bronchoscopy (AFB) has been shown to be a highly sensitive tool for the detection of early endobronchial cancers. When excited with blue-violet light, early neoplasia in the bronchi tend to show a decrease of autofluorescence in the green ...

Design of an endoscopic optical reference to be used for autofluorescence bronchoscopy with a commercially available diagnostic autofluorescence endoscopy (DAFE) system

Georges Wagnières, Tanja Gabrecht, Blaise Lovisa, François André Borle

We present the design of a sterilizable optical reference to characterize and quantify the inter-patient variations in tissue autofluorescence during autofluorescence bronchoscopy with Richard Wolf's diagnostic autofluorescence endoscopy (DAFE) system. The ...

The inverse Womersley problem for pulsatile flow in straight rigid tubes

Nikolaos Stergiopoulos

In this study a numerical solution for the problem of pulsating flow in rigid tubes is described. The method applies to the case of known flow rate waveform, as opposed to Womersley solution where the pressure gradient was the known quantity. The solution ...
