  • Method for computer recognition of projection views and orientation of chest radiographs
    Patent number: 7352888
    Abstract: A method for identifying a projection view and an orientation of a chest radiograph. The method includes the steps of: providing an input digital image of the chest radiograph; preprocessing the input digital radiographic image; classifying the view of the input digital radiographic image; and determining the orientation of the input digital radiographic image.

  • Method for automated window-level settings for magnetic resonance images
    Patent number: 7218763
    Abstract: A method of automatically determining window-level settings in a digital image of a subject. The method includes the steps of: accessing the digital image; obtaining body part or coil type information; determining a region of interest (ROI) within the digital image; producing and processing a ROI-histogram; defining a W-L value for a linear or non-linear image intensity range re-mapping; and a linear or non-linear re-mapping the image intensity range.

  • Method for antiscatter stationary grid artifacts detection and attenuation in digital radiographic images
    Patent number: 7174038
    Abstract: A method for detecting and attenuating grid artifacts in a digital radiographic image comprising; providing an input digital radiographic image; processing the input digital radiographic image with a detection algorithm based on 2-D dynamic correlation in both spatial and frequency domains to determine whether the input digital radiographic image has a grid artifacts; and if it does detecting the grid orientation, frequency, and signal-to-noise ratio of the grid artifacts, designing a frequency bandstop (notch) digital 1-D filter as a function of the grid frequency and attenuation level; and suppressing the grid artifacts by further processing said input digital radiographic image with said designed filter to produce an output digital radiographic image of improved image quality.
