Influence of obesity on the tone of bronchial smooth muscles in rats
Acta Biomedica Scientifica, 2023 Background. Overweight and obesity are key factors for the occurrence of many morphofunctional disorders in organs and tissues, including bronchopulmonary system.The aim.

FDA: Feature Decomposition and Aggregation for Robust Airway Segmentation [PDF]
arXiv, 2021 3D Convolutional Neural Networks (CNNs) have been widely adopted for airway segmentation. The performance of 3D CNNs is greatly influenced by the dataset while the public airway datasets are mainly clean CT scans with coarse annotation, thus difficult to be generalized to noisy CT scans (e.g. COVID-19 CT scans).

BREAK: Bronchi Reconstruction by gEodesic transformation And sKeleton embedding [PDF]
arXiv, 2022 Airway segmentation is critical for virtual bronchoscopy and computer-aided pulmonary disease analysis. In recent years, convolutional neural networks (CNNs) have been widely used to delineate the bronchial tree. However, the segmentation results of the CNN-based methods usually include many discontinuous branches, which need manual repair in clinical ...

Photoacoustic Imaging Based on AlN MF-PMUT with Broadened Bandwidth [PDF]
arXiv, 2022 This paper reports an aluminum nitride (AlN) multi-frequency piezoelectric micromachined ultrasound transducers (MF-PMUT) array for photoacoustic (PA) imaging, where the broadened bandwidth is beneficial to improve imaging resolution. Specifically, PMUT based on micro-electromechanical systems (MEMS) technology is suitable for PA endoscopic imaging of ...

Wall shear stress distribution in a compliant airway tree [PDF]
, 2020 The airflow in the bronchi applies a shear stress on the bronchial mucus, which can move the mucus. The air--mucus interaction plays an important role in cough and in chest physiotherapy (CP). The conditions under which it induces a displacement of the mucus are still unclear. Yet, the air--mucus interaction justifies common technics of CP used to help

Design and analysis of a wire-driven flexible manipulator for bronchoscopic interventions [PDF]
, 2016 Bronchoscopic interventions are widely performed for the diagnosis and treatment of lung diseases. However, for most endobronchial devices, the lack of a bendable tip restricts their access ability to get into distal bronchi with complex bifurcations ...

Broken safety pin in bronchus - Anaesthetic considerations
Indian Journal of Anaesthesia, 2012 Safety pins are not commonly aspirated objects in infants and form only a small fraction of all the metallic foreign body (FB) which accounts for 4.4% of all foreign bodies found in tracheobronchial tree. Bronchoscopy procedure has various complications,
