摘要： Certain embodiments of the present invention provide a system and method for structuring dynamic data from a plurality of images. Certain embodiments include accessing an image data set including data representing a plurality of images, determining a dynamic or functional attribute in the image data set, associating the dynamic or functional attribute with a lexical attribute from a lexicon, and storing the lexical attribute and an associated code. The lexical attribute and associated code may be stored in a database and/or a structured report, for example. The lexicon may be modified to accommodate attributes and medical terminology. Attributes relate to a feature and/or a region of interest in the image data set.

摘要： One or more techniques are provided for identifying a period of minimal motion for an organ of interest, such as the heart or lungs. Motion data is acquired for the organ of interest and for one or more proximate organs using sensor-based and/or image-based techniques. The sensor-based techniques may include electrical and non-electrical techniques. The image-based techniques may include both pre-acquisition and acquisition image data. The motion data for the organ of interest and proximate organs may be used to generate a set of multi-input motion data that may be processed to identify desired periods, such as periods of minimal motion, within the overall motion of the organ of interest.

摘要： A method of imaging and a system therefore are provided. The imaging system includes an image forming device for generating a first image and a second image and a controller coupled to the image forming device. The controller receives the first image and the second image. In the method the controller generates an image ratio of the first image and the second image, regularizes the image ratio of the second image with respect to the first image to form a regularized image ratio and filters the image ratio to form a filtered ratio. The controller then multiplies the second image by the filtered ratio to form an adjusted image.

摘要： A technique for enhancing discrete pixel images includes blurring or smoothing image data, and identifying structural features based upon the blurred image data. Identification of structural pixels is based upon a scaling factor which may be adjusted by an operator, providing an image enhancement framework which may be easily adapted to various types of images and image acquisition systems. Orientation smoothing of the structure may include dominant orientation smoothing based upon both a dominant orientation for each structural pixel, as well as the orientation orthogonal to the dominant orientation. Orientation sharpening is performed based upon whether structural pixel values exceed a desired threshold. The resulting technique is versatile and provides improved robustness to noise, while offering excellent enhancement of structure of interest in the reconstructed image without loss of texture.

摘要： 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.

The method and apparatus utilize motion sensing devices placed on or about the patient to obtain a motion data set from each motion sensing device describing the aggregate detected motion. The data sets are synchronized and then used to solve a set of simultaneous equations which allows for the separation of the various motion components which may include such components of interest as fetal heart motion.
