20100004588 | NANOCLAY SORBENTS FOR DIALYSIS - Dialysis is enhanced by using nanoclay sorbents to better absorb body wastes in a flow-through system. Nanoclay sorbents, using montmorillonite, bentonite, and other clays, absorb significantly more ammonium, phosphate, and creatinine, and the like, than conventional sorbents. The clays may be used in wearable systems, such as a wearable peritoneal dialysis system, in which the dialysis fluid is circulated through a filter with nanoclay sorbents. Waste products are absorbed by the nanoclays and the dialysis fluid is recycled to the patient's peritoneum. Using the ion-exchange capability of the nanoclays, waste ions in the dialysis fluid are replaced with desirable ions, such as calcium, magnesium, and bicarbonate. The nanoclay sorbents are also useful for refreshing dialysis fluid used in hemodialysis and thus reducing the quantity of dialysis fluid needed for hemodialysis. | 01-07-2010 |

20120106815 | DENOISING METHOD AND SYSTEM FOR PRESERVING CLINICALLY SIGNIFICANT STRUCTURES IN RECONSTRUCTED IMAGES USING ADAPTIVELY WEIGHTED ANISOTROPIC DIFFUSION FILTER - Embodiments and processes of computer tomography perform tasks associated with denoising a reconstructed image using an anistropic diffusion filter and adaptively weighting an iterative instance of the diffused image based upon the product of a weight value and a difference between the iterative instance of the diffused image and the original image. In general, the adaptive weighting is a negative feedback in the iterative steps. | 05-03-2012 |
20120308104 | METHOD AND SYSTEM UTILIZING PARAMETER-LESS FILTER FOR SUBSTANTIALLY REDUCING STREAK AND OR NOISE IN COMPUTER TOMOGRAPHY (CT) IMAGES - Photon starvation causes streaks and noise and seriously impairs the diagnostic value of the CT imaging. To reduce streaks and noise, a new scheme of adaptive Gaussian filtering relies on the diffusion-derived scale-space concept in one embodiment of the current invention. In scale-space view, filtering by Gaussians of different sizes is similar to decompose the data into a sequence of scales. As the scale measure, the variance of the filter linearly relates to the noise standard deviation of a predetermined noise model in the new filtering method. The new filter has only one optional parameter that remains stable once tuned. Although single-pass processing using the new filter generally achieves desired results, iterations are optionally performed. | 12-06-2012 |
20120321157 | METHOD AND SYSTEM FOR ESTIMATING NOISE LEVEL - Noise assessment is important to image quality evaluation as well as image processing. For example, the noise level estimation is used as criteria for terminating an iterative noise reduction process. To determine a meaningful noise level, the pixels in featureless regions are separated from the rest of the image. A new concept of pseudo-standard deviation (PSD) is introduced to automatically determine simple and reliable noise level estimates. Furthermore, a histogram of PSD is constructed with fine bins to calculate the moving average of the histogram. The first peak in filtered histogram gives the most representative noise measure as a desired approximation of true standard deviation. | 12-20-2012 |

20150036902 | HIGH DENSITY FORWARD PROJECTOR FOR SPATIAL RESOLUTION IMPROVEMENT FOR MEDICAL IMAGING SYSTEMS INCLUDING COMPUTED TOMOGRAPHY - A medical imaging apparatus, processing device or specialized circuit can include an input interface to input scan data of a medical image scan of a target object, a processor to generate an output image from the input scan data, and an output interface to output the output image to, e.g., a display. The processor can execute a first reconstruction of the scan data to obtain an intermediate image of the target object, a high-density forward projection of the intermediate object to obtain generated data, a sinogram updating using both of the generated data and the scan data to obtain a high-resolution sinogram, and a second reconstruction based on the high-resolution sinogram to obtain an output image. | 02-05-2015 |
