  • Adaptive processing of medical images to reduce noise magnitude
    Patent number: 11080898
    Abstract: Each of a plurality of slices of medical image data is adaptively processed using a noise reduction mode selected according to a target noise magnitude for all slices to an estimated noise magnitude for the respective slice to obtain consistent processed images for across slices, different size patients' and different reconstruction thickness. Unnecessary noise reduction and over-cleaning images resulting in inconsistent noise-level image data across slices or waxy/unnatural appearing processed images is avoided.

  • Cross directional bilateral filter for CT radiation dose reduction
    Patent number: 10891720
    Abstract: A method to denoise low dose CT images without introducing blurriness is shown using cross directional bilateral filtering. Techniques are provided that (1) enhance low-radiation dosage images, beyond just reducing noise, and (2) may be combined with other approaches, such as adaptive exposure techniques and iterative reconstruction, for radiation dose reduction.
