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 le...

Exact Local CT Based on Compressive Sampling
A system and method for tomographic image reconstruction using truncated projection data that allows exact interior reconstruction (interior tomography) of a region of interest (ROI) based on the known sparsity models of the ROI, thereby improving image quality while reducing radiation dosage. In addition, the method includes parallel interior tomo...

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.

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 d...

Methods and Systems for SPECT/PET Interior Reconstruction From Truncated Projection Data
SPECT and PET are important nuclear medicine tomographic imaging modalities. However, due to some limitations (e.g. detector length), the detected projections are often truncated. Inspired by the recent progress in the CT field, the inventors have developed a uniformly attenuated SPECT/PET interior reconstruction approach aided by partial prior k...

Multi-parameter X-ray Computed Tomography (MXCT) Methods and Systems
The MXCT method combines scattered with traditional attenuated imaging. This approach enables greater sensitivity and specificity, especially for soft biological tissues. Additional advantages include improved contrast of CT images and reduced radiation dosage. Potential applications include biomedical imaging as well as nondestructive testing.
