Stent localization in 3d cardiac images

Номер: US20120002855A1
Автор: Ying Bai
Принадлежит: Fujifilm Corp

Systems and methods are described for automatically identifying coronary stents within a 3D cardiac image. Based on feature analysis on a cardiac image, coronary stents can be detected by filtering the cardiac images for stent candidates, applying a score based on factors related to coronary stents and applying a threshold. Once coronary stents are identified, in-stent restenosis and stent fractures can be further detected.

Method and apparatus for compressed sensing yields acceptable quality reconstructions of an object from reduced numbers of measurements. A component x of a signal or image is represented as a vector having m entries. Measurements y, comprising a vector with n entries, where n is less than m, are made. An approximate reconstruction of the m-vector x is made from y. Special measurement matrices allow measurements y=Ax+z, where y is the measured m-vector, x the desired n-vector and z an m-vector representing noise. “A” is an n by m matrix, i.e. an array with fewer rows than columns. “A” enables delivery of an approximate reconstruction, x # ′ of x. An embodiment discloses approximate reconstruction of x from the reduced-dimensionality measurement y. Given y, and the matrix A, approximate reconstruction x # of x is possible. This embodiment is driven by the goal of promoting the approximate sparsity of x # .

A method is disclosed for operating a machine vision inspection system to determine a fluorescent imaging height for acquiring a fluorescent image for repeatably determining the location of a feature within the fluorescent material. The height of an exposed workpiece portion exposed outside of the fluorescent material is determined (e.g., using a height sensor or autofocus operations). The determined height is repeatable. The exposed portion has a characteristic height relative to the fluorescent material and/or features located therein. The fluorescent imaging height, which may be inside the fluorescent material, is determined relative to the determined height of the exposed portion. The fluorescent imaging height is determined such that it enhances the detection of the desired feature located within the fluorescent material in the resulting fluorescent image. For a variety of workpieces, the method provides automatic acquisition of appropriately focused fluorescent image more reliably than previously known methods.

Blur is one of the most important features related to image quality. Accurately estimating the blur level of an image is a great help to accurately evaluate its quality. A method for calculating blur of video images comprises calculating a horizontal blur value, and determining characteristic parameters of the video images, including at last progressive/interlaced and spatial resolution level. If the video images are progressive, also a vertical blur value is calculated, and combined with the horizontal blur value. The next step is normalizing the horizontal blur value, or the combined horizontal and vertical blur value, according to predefined min and max values, wherein the min and max values are adapted to the spatial resolution level.

At the time of processing of an image signal from an image sensor mounted in a small electronic apparatus (e.g. a mobile apparatus), in order to remove noise, certain steps are performed, in accordance with embodiments. Edge values may be detected from an area to be smoothed to detect a feature point. Weights depending on a geometric distance with respect to the feature point may be applied to pixels distributed in the smoothed area. A brightness value as reference may be calculated in consideration of a difference in brightness between a center pixel and a peripheral pixel. Weights may be applied depending on the brightness values of the pixels to perform smoothing. It may therefore be possible to effectively remove noise while maintaining the level on the edge area.

View-specific object detectors are learned as a function of scene geometry and object motion patterns. Motion directions are determined for object images extracted from a training dataset and collected from different camera scene viewpoints. The object images are categorized into clusters as a function of similarities of their determined motion directions, the object images in each cluster are acquired from the same camera scene viewpoint. Zenith angles are estimated for object image poses in the clusters relative to a position of a horizon in the cluster camera scene viewpoint, and azimuth angles of the poses as a function of a relation of the determined motion directions of the clustered images to the cluster camera scene viewpoint. Detectors are thus built for recognizing objects in input video, one for each of the clusters, and associated with the estimated zenith angles and azimuth angles of the poses of the respective clusters.

Framework for reference-free drift-corrected planar tracking using lucas-kanade optical flow

Номер: US20130076915A1
Автор: Ashwin Swaminathan, Mahesh Ramachandran, Murali R. Chari, Serafin Diaz Spindola
Принадлежит: Qualcomm Inc

Reference free tracking of position by a mobile platform is performed using images of a planar surface. Tracking is performed optical flow techniques, such as pyramidal Lucas-Kanade optical flow with multiple levels of resolution, where displacement is determined with pixel accuracy at lower resolutions and at sub-pixel accuracy at full resolution, which improves computation time for real time performance. Periodic drift correction is performed by matching features between a current frame and a keyframe. The keyframe may be replaced with the drift corrected current image.

Semi-Automated Preoperative Resection Planning

Номер: US20130077842A1
Автор: Christian Tietjen, Leo Grady, Michal Sofka, Noha Youssry El-Zehiry, Shaohua Kevin Zhou
Принадлежит: SIEMENS AG

Preoperative resection planning is assisted by a computer. Rather than rely on interpolation of the user input, a graph of interconnections is used. The user inputs one or more polylines on one or more two-dimensional views. The polylines are used to assign resection and remnant seeds with a band of unassigned locations. The 2D seeds are used with the graph of interconnections to assign different voxels in the volume, including the unassigned locations, as being part of the resection volume or part of the remnant volume.
