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 ...

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 se...

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. Vir...

Systems and Methods for Fast Quasi-Exact Triple-Source Helical Cone-Beam CT
Cardiac computed tomography (CT) has been improved over past years, but it still needs improvement for higher temporal resolution in the cases of high or irregular cardiac rates. Given successful applications of dual-source cardiac CT scanners, triple-source cone-beam CT seems a promising mode for cardiac CT.
