Development of a quasi-three-dimensional portable mobile chest tomosynthesis system using carbon nanotube technology for enhanced diagnostic imaging
Year: 2025
Type: dissertation
Abstract: Traditional mobile chest radiography is limited by the challenges of two-dimensional imaging, which can obscure anatomical details. This project advances an integrated X-ray system utilizing a carbon nanotube source to enable tomosynthesis, a limited-angle tomography technique that provides quasi-three-dimensional imaging for improved bedside visualization. As part of the development process, a custom collimator was modeled and an intuitive graphical user interface was created—both serving as key proofs of concept for future clinical implementation. The system incorporates the CNT source array and supporting electronics into a commercially available mobile cart. While additional refinement is needed for clinical readiness, preliminary testing demonstrates the system's viability.
