Advanced Engineering Materials, EarlyView.This study proposes a potential device design for joint cartilage replacement. Silica‐polytetrahydrofuran (SiO2‐PolyTHF) hybrids with customizable mechanical properties were developed to mimic the characteristics of a natural meniscus. These were synthesized through a two‐pot sol–gel hybrid process.

Markerless tracking of tumor and tissues: A motion model approach
Medical PhysicsAbstractBackgroundRespiratory motion management is essential in order to achieve high‐precision radiotherapy. Markerless motion tracking of tumor can provide a non‐invasive way to manage respiratory motion, thereby enhancing treatment accuracy. However, the low contrast in real‐time x‐ray images for image guidance limits the application of markerless ...
