Construction of human bronchial trees from computed tomography scans through machine learning and stochastic growth algorithms

Published on 2026-05-21 by @OXFORD

Abstract: AbstractDigital twins of human lungs are of great value for healthcare, pharmaceutical, and bio-engineering communities. They can be used to study ventilation and gas mixing problems informing and improving the design of assisted ventilation devices. They can also provide an estimate of the occupational exposure to toxic or pathogenic aerosols. Furthermore, they can be employed to optimize therapeutic aerosols and their delivery through inhalers or nebulizers. Fundamental for all these applicati[...]


Our summary: This study presents a method for constructing human bronchial trees using machine learning and stochastic growth algorithms from CT scans. It focuses on generating accurate 3D models of the bronchial tree and lung lobe volumes. The research evaluates the quality and physiological accuracy of the generated models compared to existing morphometric data.

A systematic framework for motion artifact removal

Published on 2026-04-07 by @MIT

Abstract: AbstractFunctional ultrasound imaging (fUSI) is a promising tool for studying brain activity in awake and behaving animals, offering insights into neural dynamics that are more naturalistic than those obtained under anesthesia. However, motion artifacts pose a significant challenge, introducing biases that can compromise the integrity of the data. This study provides a comprehensive evaluation and benchmarking of strategies for detecting and removing motion artifacts in transcranial fUSI acquisi[...]


Our summary: This study evaluates 792 denoising strategies for removing motion artifacts in functional ultrasound imaging of awake mice. It highlights the effectiveness of adaptive clutter filtering and aCompCor confound regression in preserving data integrity. Two optimized denoising paradigms are proposed to enhance fUSI data reliability and reproducibility.
