摘要： Systems, methods, and other embodiments are disclosed for correcting errors in the geo-spatial locations of acquired image data. In one embodiment, acquired aerial or satellite image data is segmented to generate extracted boundary data. The extracted boundary data represents boundaries of features of a portion of the Earth's surface, but at incorrect geo-spatial coordinates. The extracted boundary data is matched to expected boundary data derived from ground truth data. The expected boundary data represents boundaries of the features at correct geo-spatial coordinates. Adjustment parameters are generated that represent a geo-spatial misalignment between the extracted boundary data and the expected boundary data. Metadata in a header of the acquired image data is modified to include the adjustment parameters. The adjustment parameters may be applied to the acquired image data to generate corrected image data at correct geo-spatial coordinates.

摘要： The invention concerns automated methods for assessing tissue morphometry in digital images of tissue sections derived from small intestine biopsy samples from patients submitted for evaluation of celiac disease. The methods generally involve digital image analysis of tissue section images, and specifically involve post-processing each image to produce a binary mask capturing the tissue area footprint on the glass slide. Virtual stereology probes are placed on each image and assessed to estimate the ratio of the surface area to volume of the tissue specimen. The surface area to volume ratio is used to diagnose celiac disease and make inferences about the severity of celiac disease in those individuals with a positive diagnosis of celiac disease.

摘要： A method for segmenting a volume dataset is provided. During initialization a level set field within a volume dataset is initialized and an initial set of active voxels is determined in dependence upon the initialized level set field. In an iteration process the level set field for the set of active voxels is updated followed by updating of the set of active voxels. The iteration is continued until the number of active voxels is less than a predetermined threshold. Level set segmentation data are then determined in dependence upon the level set field and provided for, for example, graphical display or storage.

摘要： A radiation therapy system includes a diagnostic image scanner (12) which acquires a multidimensional dataset of a subject that is reconstructed into at least one image representation of an object of interest. An image processing apparatus (72), of radiation therapy system, includes a segmentation unit (74) which identifies a surface contour of the object of interest, or other critical structures. A masking unit (82) determines a non-constant margin, based on the identified surface contour and appends the determined non-constant margin to the identified surface contour. The non-constant margin is based on at least one of anisotropic motion, surface morphology, positional uncertainty, proximity to other organs, and probability of dose distribution. A planning processor (70) generates a radiation therapy plan which limits the delivery of therapeutic radiation to anatomy associated with the surface contour and appended non-constant margin. A radiation delivery system (40) delivers therapeutic radiation according to the generated plan.

摘要： A radiographic image processing apparatus in this invention decreases a spatial resolution twice in total by a low-frequency image generating device and a low-frequency characteristic generating device. Thereby an influence such as noise and thus calculation amounts are decreased. Moreover, excessive characteristic amounts (patterns) not removed among characteristic amounts extracted through the low-frequency image generating device and a characteristic extracting device can be decreased by decrease of the spatial resolution by the low-frequency characteristic generating device. Consequently, influence such as noise and calculation amounts can be decreased for the low-frequency characteristics generated by the low-frequency characteristic generating device and a radiation area extracted by an area extracting device on the latter stage. As a result, influences such as noise can be decreased for achieving characteristic extraction and area extraction with high accuracy, and thus calculation amounts can be decreased.

摘要： An image measurement apparatus includes: an imager section, an obtainment section, an outline detection section, a setting section, and a measurement section. The imager section takes an image of a subject to be measured. The obtainment section obtains a taken image of the subject taken by the imager section. The outline detection section detects, by a Hough transformation, outline of a graphic included in the image obtained by the obtainment section. The setting section sets an edge detection tool on the outline detected by the outline detection section. The measurement section measures, by the edge detection tool set by the setting section, graphic information concerning the graphic.
