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.

摘要： A method of adaptively reducing noise within an x-ray image includes receiving raw data (R) representing a detected x-ray signal from an object. A counts-based modulation mask (Mcb) is generated in response to the raw data (R). In one embodiment, a structure dependent noise filtered image (Iblended) is generated in response to the raw data. A noise-reduced image (IF) is generated in response to the counts-based modulation mask (Mcb) and the structure dependent noise filtered image (Iblended). In another embodiment, a structure gradient mask (Mcs) is generated in response to the raw data (R). The noise-reduced image (IF) is generated in response to the counts-based modulation mask (Mcb) and the structure gradient mask (Mcs).

摘要： Systems and methods are provided for optimizing visual consistency for a dataset of images by using observed and formulated display attributes. The formulated display attributes are derived from an analysis of a first set of images from the image repository. The formulated display attributes from the first set are combined with observer's display attributes to determine scaling factors. The optimized display attributes are then derived from the calculated scaling factors for a second set of images. In another aspect, a system and method is described where a digital image is processed in order to enhance viewing of the image on a display device in accordance to the optimized attributes associated with the observer.
