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...

Methods and Systems for Ranking Academic Units
Collaboration among researchers is becoming more important, reflecting the increased complexity of interdisciplinary research and improving the quantity and quality of the resultant publications. One main challenge is how to evaluate the contributions of individuals in the collaboration. Traditional metrics such as H-index assume equal contribution...

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...

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.

Combination of Photon-Integrating/Counting Detector Moduli for Spectral CT
Spectral computed tomography (CT) systems are a critical diagnostic tool in medicine. CT machines use computerized x-ray imaging to produce cross-sectional images of the body. Improvements in CT imaging technologies can lower radiation exposure and support life-saving interventions. Current spectral systems can be expensive to implement and may provide...

Omni-Tomography Methods and Systems Based on Stationary Sub-Systems
Early screening, disease staging, therapeutic assessment, interventional guidance, and other aspects of "personalized medicine" are increasingly associated with multimodality imaging and targeted agents. We disclose omni-tomography based on STATIONARY SUBSYSTEMS that are much easier to integrate and shield without significant electromagnetic interference....

Compressive Bioluminescence Sensing
Many promising optical molecular imaging modalities, such as bioluminescence tomography (BLT) and fluorescence molecular tomography (FMT) face limitations in detecting deeply embedded optical molecular probes. Based on a biopsy-like optical signal acquisition technique, compressive-sensing-based computational optical biopsy (CSCOB) alleviates the detection...
