Latest Patents

Among his latest patents is a "System and method for image reconstruction for helical cone beam computed tomography with factorized redundancy weighting." This invention involves a method and system for computed tomography where weighted data is utilized to reconstruct images. The apparatus includes an x-ray source that produces a cone-beam of x-rays, an x-ray detector to receive these x-rays, a data collection unit, and a processing unit that processes the data using a weighting function derived from both fan-beam and cone-beam weighting functions. This innovative apparatus can produce images with reduced artifacts, enhancing the quality of medical imaging.

Another significant patent is the "Method and system for multi-detector-row computed tomography utilizing projection data up-sampling with shift." This invention describes a computed tomography apparatus and method where data is upsampled with shifting to generate upsampled data. The data is shifted in the z-direction and then upsampled through interpolation, allowing for the reconstruction of images using the upsampled data. The process is designed to be performed column-by-column, with the upsampling shift and interpolation kernel size being adaptive to the data z-gradient.
