20100104151 | Method for Deriving Amount of Dense Tissue from Mammographic Image - A region of interest in the image is determined and for each pixel in each location (x,y) in that region of interest a value h | 04-29-2010 |
20100189375 | Method and System for Changing Image Density and Contrast - At least one of two enhancement methods for changing contrast and/or density are applied to an image. According to a first enhancement method the window width/level settings of the image are modified and according to a second enhancement method density and contrast of the image are modified by modifying a multi-scale representation of the image whereby modification is derived from at least two gradient functions determined at different scales, a gradient function at a specific scale specifying the dependency of contrast amplification at said scale as a function of density. The amount of modification obtained by applying either of said first and second enhancement methods is determined by the amount of movement of at least one indicium. | 07-29-2010 |
20100195886 | Method of Generating a Multiscale Contrast Enhanced Image - At least one approximation image is created of the image at one or multiple scales. Translation difference images are created by pixel-wise subtracting the values of an approximation image at scale s and the values of a translated version of the approximation image. A non-linear modification is applied to the values of the translation difference image (s) and at least one enhanced center difference image at a specific scale is computed by combining the modified translation difference images at that scale or a smaller scale with weights w | 08-05-2010 |
20110026792 | Method of Enhancing the Contrast of an Image - A method of generating a multiscale contrast enhanced image is described wherein the shape of edge transitions is preserved. Detail images are subjected to a conversion, the conversion function of at least one scale being adjusted for each detail pixel value according to the ratio between the combination of the enhanced center differences and the combination of the unenhanced center differences. Several adaptive enhancement measures are described. | 02-03-2011 |
20110123089 | Method and System for Enhancing Contrast of Spatially-Localized Phenomena in Mammography Image - In a method to enhance the contrast of spatially-localized phenomena in an image such as microcalcifications in a mammogram, a multi-scale decomposition is applied to a digital signal representation of the image thereby generating a number of detail images at different scales, the detail signals pertaining to the spatially-localized phenomena having a common polarity (either negative or positive) being modified at at least one scale. | 05-26-2011 |
20130308851 | Irradiation Field Recognition - A method to extract irradiation field areas in an X-ray image represented by a digital signal representation comprising the steps of segmenting the image in multiple regions of pixels which have similar local image characteristics, fitting line segments to the boundaries of these regions whereby said line segments correspond with candidate irradiation field boundaries and constitute a segmentation map, classifying regions in said segmentation map into at least two classes, one class being irradiation field and the other class being collimated region on the basis of at least one of local, regional and global image characteristics. | 11-21-2013 |
20140219423 | CALIBRATION FREE DUAL ENERGY RADIOGRAPHY METHOD - A method of generating a bone and a soft tissue image of an object includes a dual energy radiography technique wherein weight parameters for calculating these images as a weighted sum of a low energy image P | 08-07-2014 |

20100266183 | Method of Generating a Multiscale Contrast Enhanced IMage - A digital image signal is decomposed into a multi-scale representation comprising detail images and approximation images. Translation difference images are computed by subtracting an approximation image at scale s and a translated version of that approximation image. The values of the translation difference images are non-linearly modified. An amplification image is computed at least one scale as the ratio of a first image being computed by combining the modified translation difference images at the same or smaller scale and a second image created by combining unenhanced translation difference images at the same or smaller scale. Next, an enhanced multi-scale detail representation is computed by modifying at least one scale the detail image according to the amplification image at that scale. An enhanced image representation is computed by applying a reconstruction algorithm to the enhanced multi-scale detail representation. The non-linear modification of the values of the translation difference image is steered by the values of an orientation map which comprises for each pixel on a specific scale a local direction of interest. | 10-21-2010 |

20090052631 | System and Method for Information Embedding and Extraction in Phantom Targets for Digital Radiography Systems - A system and method for embedding in a phantom target used in digital radiography systems information specific to the phantom target, such as serial number, phantom target type, precision landmarks, composition, physical properties of the dedicated targets and the like. The information is encoded and represented by small holes in the phantom target that can easily and unambiguously be detected by decoding-software acting on the radiation image of the phantom target. A look-up table or any other flexible data structure defines the functionality of the holes detected based on their image-location. Regions of interest can be located based on an internal coordinate system defined accurately by the sub-pixel position of the hole centres. | 02-26-2009 |
