20090129673 | METHOD FOR SEGMENTATION OF LESIONS - A method of image segmentation includes receiving a set of voxels, segmenting the set of voxels into a foreground group and a background group, and classifying voxels of the foreground group as either lesion voxels or normal anatomy voxels. The method also includes blocking the normal anatomy voxels and performing a second segmentation on voxels of the background group and the lesion voxels, the second segmentation forming a stage two foreground group comprising the lesion voxels and a portion of the voxels of the background group. The method further includes classifying voxels of the stage two foreground group as either stage two lesion voxels or stage two normal anatomy voxels. | 05-21-2009 |
20090185731 | METHOD FOR LUNG LESION LOCATION IDENTIFICATION - A method and a system are disclosed for labeling an anatomical point associated with a lesion in an organ such as a lung. The method includes: a segmentation of a vessel tree anatomical structure starting from an autonomously determined initial image point; labeling the vessel segments of the vessel tree segmentation with segment labels based on a priori anatomical knowledge, thereby creating an individualized anatomical model; receiving a user-specified image point having a location from a user and locating a nearby vessel structure; tracking along the vessel structure in a direction towards a root of a parent vessel tree until a prior labeled vessel segment is encountered in the anatomical model, and assigning the label of the encountered prior labeled vessel segment from the anatomical model as an anatomical location label of the user-specified image point. | 07-23-2009 |
20090279754 | METHOD FOR INTERACTIVELY DETERMINING A BOUNDING SURFACE FOR SEGMENTING A LESION IN A MEDICAL IMAGE - A method of bounding an anatomical object of interest in a 3-dimensional volume image includes displaying an image of at least a portion of the object, selecting a plurality of points in the displayed image, at least a first and second point of the plurality of points spanning the object, forming a non-rectilinear surface bounding the plurality of points, identifying a seed point within the surface and extracting a plurality of statistical values corresponding to image voxels disposed proximate the seed point, and classifying image voxels within the surface into a first class and a second class based on the plurality of statistical values. | 11-12-2009 |
20090279755 | STATISTICS COLLECTION FOR LESION SEGMENTATION - A method of collecting information regarding an anatomical object of interest includes displaying an image characterized by a first region and a second region, wherein the first and second regions are mutually exclusive and the object is displayed within the second region, selecting first and second points spanning the object in the displayed image, at least one of the points being within the first region, and extracting a plurality of statistical values from image voxels, lying on a line segment between the first and second points, that correspond to the object. | 11-12-2009 |
20090279756 | METHOD FOR EDITING 3D IMAGE SEGMENTATION MAPS - A digital image editing method includes receiving a three-dimensional volume image of an anatomical object of interest, wherein the volume image is characterized by first and second mutually exclusive segmentation classes. The method also includes deriving a two-dimensional slice image from the volume image, selecting a single point on the slice image within the second segmentation class, and defining a plane in response to the selection of the single point, the plane dividing the second segmentation class into a target portion corresponding to the object and a remainder portion. | 11-12-2009 |
20110317888 | LIVER LESION SEGMENTATION - A method for segmenting a first object from a bounding object within a digital image identifies pixels between first and second endpoint pixels. A volume of interest is defined spanning at least a portion of the object. Pixels within the volume of interest are partitioned into a first subset of pixels that are neither the first object nor bounding object pixels and second subset of pixels that are not contained in the first subset. A spatially varying two-phase segmentation process segments the first object from the bounding object within the second subset of pixels according to the location of each subject pixel within the second subset relative to pixels in the first subset of pixels. The first object segmentation is refined according to the subject pixel location relative to the segmented bounding object and to the first subset of pixels. A segmented image is formed according to the refined segmentation. | 12-29-2011 |
20130010080 | METHOD AND APPARATUS FOR MAPPING IN STEREO IMAGING - A method for registering a first imaging detector to a surface projects a sequence of k images toward the surface, wherein k≧4, wherein each of the k images has a pattern of lines that extend in a direction that is orthogonal to a movement direction. The pattern encodes an ordered sequence of labels, each label having k binary elements, such that, in the movement direction, any portion of the pattern that is k equal increments long encodes one label of the ordered sequence. The method obtains, for at least a first pixel in the first imaging detector, along at least one line that is parallel to the movement direction, a first sequence of k signal values indicative of the k binary elements of a first label from the ordered sequence of labels and correlates the at least the first pixel in the first imaging detector to the surface. | 01-10-2013 |
20150043712 | IMAGING SYSTEM AND METHOD FOR PORTABLE STEREOSCOPIC TOMOGRAPHY - A portable imaging apparatus for obtaining stereoscopic radiography images has a transport frame that has a support structure and an x-ray source array that is coupled to the support structure and that has three or more x-ray sources, each x-ray source separately energizable to emit radiation toward a subject. There is at least one x-ray detector adapted to acquire digital image data according to radiation received from the x-ray sources of the x-ray source array. An image processor is in signal communication with the at least one x-ray detector and adapted to generate, from the acquired digital image data, a right-eye digital image and a left-eye digital image of the subject. A display apparatus is in signal communication with the image processor and is adapted to display the right-eye and left-eye digital images of the subject to a viewer. | 02-12-2015 |
