  • Noise reduction in image domain for spectral computed tomography
    Patent number: 9330443
    Abstract: A computed tomography (CT) imaging system is provided including processing circuitry configured to obtain a plurality of basis images that are combined to generate a target image; de-noise the basis images using a noise-reduction method to generate de-noised basis images; calculate noise maps of the basis images by subtracting the de-noised basis images from the basis images; calculate a weight for each of the noise maps using the target image and the calculated noise maps; and generate a reduced-noise target image using the target image, the calculated noise maps, and the calculated weights.

  • Method and system for substantially reducing ring artifact based upon ring statistics
    Patent number: 8929507
    Abstract: The current invention is generally related to an image processing method and system for substantially reducing ring artifacts. Using the attenuation data, the ring artifacts are substantially prevented based upon two-step process, and the second ring artifact reduction step removes the undesirable rings based upon previously determined statistical data including mean and standard deviation.

  • Image domain based noise reduction for low dose computed tomography fluoroscopy
    Patent number: 8687871
    Abstract: A method of computed-tomography and a computed-tomography apparatus in which x-ray projection data is acquired at a number of views for a scan of an object. Partial images are created from data for a desired number of said views. Full scan images are created from plural ones of the partial images. Non-overlapping time images are created from the full-scan images. Gradient images are also created. An improved image is created by weighting respective ones of the full scan and non-overlapping time images using the gradient image. The improved image has increased sharpness with reduced noise.
