Abstract: Procedures for providing health care to a range of anatomies that require contrast agents for adequate imaging. Image data is acquired in accordance with a range of modalities, and at different times and on different patients, depending upon the particular implementation. The image data is processed in accordance with one of a range of manners and algorithms for a particular purpose and a specific tissue or organ. The resulting workflow paths provide novel combinations for rendering health care to specific tissues and organs by the use of contrast agent-based imaging.

Abstract: Systems, methods and apparatus are provided through which in one aspect, a three-dimensional (3D) image of an object is constructed from a plurality of two-dimensional (2D) images of the object using a specialized filter. The specialized filter implements a linear ramp function, a windowing function, and/or a polynomial function. The 3D image is back-projected from the filtered two-dimensional images, yielding a 3D image that has improved visual distinction of overlapping anatomic structures and reduced blurring.

Abstract: A method and computer program product for processing a digital image is disclosed. A foreground region relating to an imaged object is estimated, a background region relating to other than the imaged object is estimated, and by using the image, the estimated foreground region and the estimated background region, a transition region disposed between the foreground region and the background region is calculated. The estimated foreground region, the estimated background region, and the calculated transition region, each include a separate set of pixels that may each be processed separately for suppressing pixel intensities in the estimated background region and improving image quality.

Abstract: Signal-adaptive noise reduction in digital radiographic images is described herein. Embodiments comprise methods for signal-adaptive noise reduction in digital radiographic images, comprising the steps of: obtaining raw x-ray image data of an imaged object; processing the raw x-ray image data to create processed x-ray image data; inputting at least one of the raw x-ray image data and the processed x-ray image data to an image processor; developing at least one of a first intensity modulation image from the raw x-ray image data and a second intensity modulation image from the processed x-ray image data; deriving a structure-dependent noise filtered image using the processed x-ray image data; performing signal attenuation-dependent blending; and creating a noise-reduced digital x-ray image therefrom. Computer-readable mediums encoded with programming for facilitating signal-adaptive noise reduction in digital radiographic images, and digital radiographic imaging systems comprising such programming, are also described.

Abstract: A technique is provided for filtering noise in digital image data, particularly random point or spike noise. Image data may be rank order filtered and absolute differences between ordered values computed to create a mask. Blending is performed based upon a likelihood that individual pixels are or exhibit spike noise. The rank order filtered values may be used directly for blending, or the original image may be shrunk and then expanded to provide a rapid and computationally efficient spike noise reduction alternative.

Abstract: A technique is provided for non-uniform weighting in back-projection calculations in tomosythesis. The non-uniform weighting may include weighting based on a count map of the number of times pixels of individual slices are traversed by radiation in different projections. Weighting may also include non-uniform functions for contributions of features at different slice level to the sensed X-ray attenuation system response inconsistencies are accounted for by further weighting based upon projection maps which may be created in separate system calibration or configuration routines.

Abstract: A technique is provided for processing image data based upon determination of whether pixilated data tends to represent or exhibit one characteristic or another. Many such characteristics may be considered, such as whether the pixels probably represent structures or non-structures. Multiple thresholds for the classification of segmentation are used, and pixels falling within an overlapping regions are processed as if they exhibited both characteristics. Subsequent processing may include assignment of values for the overlapping pixels, such as by weighted blending.
