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...

Tomogranphy - Interior Tomographsiome
In this disclosure, the tomogranphy approach, systems and methods are suggested. This disclosure is related to our earlier disclosures on interior tomography, interior SPECT, and interior MRI but it represents a higher level integration and a paradigm shift. It is significantly distinguished from the current multi-modality theory and practice in several...

Method to Improve Biomedical Images Produced by Limited-Angle Radiological Scanning
Producing high resolution medical images while minimizing radiation exposure is one of the challenges in the field of computer tomography. With current technology, scanning a limited area results in internal problems giving unclear imaging. In addition, the scan exposes the patient to high amounts of radiation, even when scanning small areas. Virginia...
