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...

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....

Data Reordering for Improved Reconstruction of MRI Data

Invention Description: This invention describes a novel method to improve the reconstruction of images from sparse multi-image MRI data. By using appropriate constraints along with reordering data from multiple images, data obtained from variable density undersampling or training data may be used even though it is a lower resolution. This method...

A Real-Time Navigated Singleshot Acquisition Technique for High Resolution 3D MR Imaging

Invention Summary: The technology presents two techniques to improve the spatial resolution, quality, and the accuracy of diffusion weighted (DWI) and diffusion-tensor MR imaging (DTI). Artifacts induced by susceptibility variations near the tissue interfaces and the subject's motion during data acquisition are the factors that limit the spatial...

A Non-Iterative Image Deblurring Method to Compensate for a Non-Stationary Point Response Function

Invention Description: In many imaging applications, especially in nuclear medicine such as SPECT (single photon emission computed tomography) and PET (positron emission tomography), the images are blurred due to finite detector resolution. This invention is a fast, non-iterative algorithm to de-blur the image that is suffered from non-stationary...
