A Filtered Backprojection Algorithm with Characteristics of the Iterative Landweber Algorithm

Invention SummaryA new algorithm has been developed based on Filtered Back-Projection (FBP), but included is a control parameter k that gives an equivalent result to that of the kth iteration of the Landweber algorithm. With that said, the algorithm can be used in all image modalities that use FBP/iterative 3D image reconstruction algorithms: X-ray...

3T Sodium and Proton Composite Array for Magnetic Resonance Imaging

Invention SummaryBreast cancer is the most common type of cancer affecting women and is a leading cause of mortality. Early diagnosis, early treatment, and early assessment of treatment can dramatically increase survival rates. While mammography is typically used to detect breast cancer, contrast-enhanced proton MRI has been shown to be more sensitive....

Precise Reconstruction of CT Images at Arbitrary Pitch Values

Invention SummaryA novel theoretically-exact and stable (TES) image reconstruction algorithm for helical cone-beam computed tomography (CT) has been developed and is available for licensing. The resulting image is a combination of at least two sets of image data detected by a detector within and outside of its Tam-Danielsson (TD) window. The combination...

Cone-Beam Reconstruction Using the Backprojection of Locally Filtered Projections

Invention SummaryTechnology for X-ray detection in cone-beam geometry is rapidly improving and offers more and more potential for the construction of robust computed tomography systems for high-resolution volume imaging. In order to optimally build such systems, the problem of cone-beam image reconstruction needs to be understood. Our technology consists...

System and Method for Sub-Diffraction-Limited Patterning

Invention SummaryMethod for creating nanoscale patterns using long wavelength photons and traditional photolithography. The technique involves the use of a switchable photoresist material that can be scanned in an iterative process prior to a locking step required for final processing. Nanoscale physical features beyond the diffraction limits of extreme...

Ultrasonic Method for Determining Tissue Pathology and Assessing Tumor Margins

Invention Summary Surgeons performing cancer, biopsy, or other clinical treatments can determine whether additional tissue needs to be removed in order to acquire a cancer free margin. High-frequency ultrasound is sensitive to tissue properties and structure at the microscopic level, and thus is specifically useful for detecting microscopic...

Method for Diagnosing Bipolar Disorder Using 31-Phosphorus Magnetic Resonance Spectroscopic Imaging of the Brain

Invention Summary: Research from several scientific disciplines has implicated mitochondrial dysfunction, and consequent impaired energy supply in the brain, in the neurobiology of Bipolar Disorder (BD). The levels of phosphorus chemicals in the brain are indices of mitochondrial functioning. 31-phosphorus magnetic resonance spectroscopy (31P-MRS)...

Fast 3D Tomographic Projector/Backprojector

Invention Summary: Calculation of volumetric projection/backprojection is necessary for reconstruction of tomographic data (e.g. PET, SPECT, CT scanners), but this computation can be very time consuming. This fast projector/backprojector greatly reduces the time needed for reconstruction of 3D tomographic data, while at the same time computing a...

Head and Neck Positioning System for Repeatable Head and Neck MR Imaging

Invention Summary: University of Utah researchers have developed an exciting new device and method for supporting and positioning the human head and neck for repeatable MR imaging. This device is especially useful for repositioning the head for carotid artery studies where even a small difference in head position can render imaging results useless....
