项目摘要
Abstract/Project Summary
The objective of this program is to improve cone-beam computed tomography (CBCT) imaging performed on
an interventional C-arm for guiding catheter-directed embolization of liver tumor in particular, and multiple other
interventional procedures. The current standard of care for hepatic catheter directed therapy uses an
interventional C-arm and injected contrast agent to visualize tumor and its feeding vessels. C-arm CBCT can
be used to understand the lesion anatomy, allowing 3D visualization of the tumor and feeding vessels.
However, current C-arm CBCT is far from being optimized for the application due to a number of important
limitations concerning exam time, radiation dose, image quality, and intrusiveness to workflow. These
limitations can be addressed through the development of innovative CBCT scans and optimization-based
reconstructions. In the project, we focus on tackling the practical limitations of the C-arm CBCT in image-
guided liver-tumor catheter delivery through the development of innovative scans and optimization-based
reconstructions, and demonstrating their translational potential to clinical tasks of image-guided liver-tumor
treatment. The specific aims of the project include (1) to develop optimization-based reconstruction for
improving current C-arm imaging, (2) to develop scans and optimization-based reconstruction for further
improving C-arm imaging, and (3) to verify, characterize, and evaluate optimization-based reconstructions. The
clinical and technical significances of the project are high, because it can directly impact significantly
intervention and treatment of liver-cancer and other forms of cancer, particularly, in the lung and kidney, and
because it can lead to the development of advanced C-arm CBCT technology for addressing technical
challenges such as sparse-view, truncation, and limited-angular-range problems of extremely high practical
merit. The project has a high level of innovation, because it includes numerous creative ideas and methods for
enhancing workflow and for reducing contrast volume, radiation dose, and patient discomfort.
