Structure Illuminated Color X-ray Phase Imaging for Breast Cancer Screening
One in every nine women is expected to develop breast cancer in her life. Current mainstream screening technology is the mammography. Mammography suffers from a range of problems including low signal level, poor contrast, and radiation dose. It leads to severe over-diagnostic problems. In contrast, our breast cancer screening system with color X-ray...

Ultrafast Micro-CT for Imaging Free-Moving Animals
All current small animal imaging requires some form of anesthetization. The anesthetization not only may interfere with the subject's pathophysiology under study, and also is a costive and skill-demanding process. The current invention will eliminate the need for administration of anesthesia during small animal micro-CT imaging experiments, thus leading...

System and Method of Stationary Source Computed Tomography
Cardiovascular computing tomography (CVCT) has been successfully applied for the diagnosis of a series of heart diseases. However, the limitations of temporal and spatial resolution and radiation dose inhibit the utilization of CVCT for more clinical applications. The specific primary bottlenecks fo the current CVCT include the difficulties of the synchronization...
