Neural Radiance Fields for High-Fidelity Soft Tissue Reconstruction in Endoscopy.
Sensors (Basel)
January 2025
Shanghai Film Academy, Shanghai University, Shanghai 200072, China.
The advancement of neural radiance fields (NeRFs) has facilitated the high-quality 3D reconstruction of complex scenes. However, for most NeRFs, reconstructing 3D tissues from endoscopy images poses significant challenges due to the occlusion of soft tissue regions by invalid pixels, deformations in soft tissue, and poor image quality, which severely limits their application in endoscopic scenarios. To address the above issues, we propose a novel framework to reconstruct high-fidelity soft tissue scenes from low-quality endoscopic images.

: This study aimed to compare the effects of surgically assisted rapid palatal expansion (SARPE) techniques and their combinations on the stresses (von Mises, maximum principal, and minimum principal) and displacements that occur in the maxilla, facial bones, and maxillary teeth using three-dimensional finite element analysis (FEA). : SARPE was simulated using seven different osteotomy techniques. The FEA models were simulated with a combination of various osteotomies, including midpalatal and lateral osteotomies, lateral osteotomy with a step, and separation of the pterygomaxillary junction.

Innovation in Research & Engineering Solutions (IRES), 1000 Brussels, Belgium.
In modern manufacturing environments, pollution management is critical as exposure to harmful substances can cause serious health issues. This study presents a two-stage computational fluid dynamic (CFD) model to estimate the distribution of pollutants in indoor production spaces. In the first stage, the Reynolds-averaged Navier-Stokes (RANS) method was used to simulate airflow and temperature.

Due to advances in big data technology, deep learning, and knowledge engineering, biological sequence visualization has been extensively explored. In the post-genome era, biological sequence visualization enables the visual representation of both structured and unstructured biological sequence data. However, a universal visualization method for all types of sequences has not been reported.

: Frontal knee malalignments are hallmarks of Achondroplasia (ACH), along with disproportional short stature. Typically, X-rays are used to assess them, but 3D gait analysis (3DGA) may additionally be used to evaluate dynamic knee function. The research questions were as follows: (1) What is the relationship between X-rays and 3DGA in ACH? (2) Do children with ACH have abnormal frontal knee kinematics and kinetics? (3) Are there aspects of 3DGA that relate to knee symptoms? : A total of 62 knees of 31 children with ACH (age: 11.
