Publication number: 20140107945Abstract: A method, starting from acoustic emission signals of a material under examination, for determining parameters dynamically characterizing an ageing state of a material is described. The method focuses on solid material properties that are widely sub-microscopic and as such are non-observable by any other known experimental method.Type: ApplicationFiled: March 20, 2012Publication date: April 17, 2014Inventor: Giovanni Gregori

Patent number: 8319974Abstract: A system, method and apparatus for anatomical mapping utilizing optical coherence tomography. In the present invention, 3-dimensional fundus intensity imagery can be acquired from a scanning of light back-reflected from an eye. The scanning can include spectral domain scanning, as an example. A fundus intensity image can be acquired in real-time. The 3-dimensional data set can be reduced to generate an anatomical mapping, such as an edema mapping and a thickness mapping. Optionally, a partial fundus intensity image can be produced from the scanning of the eye to generate an en face view of the retinal structure of the eye without first requiring a full segmentation of the 3-D data set. Advantageously, the system, method and apparatus of the present invention can provide quantitative three-dimensional information about the spatial location and extent of macular edema and other pathologies.Type: GrantFiled: March 8, 2011Date of Patent: November 27, 2012Assignee: Carl Zeiss Meditec, Inc.Inventors: Robert W.

Publication number: 20060100527Abstract: A system, method and apparatus for speckle noise removal based upon structural correlation in an OCT imaging system. In accordance with the present invention, several two- or three-dimensional OCT image scans can be acquired for processing by an adaptive algorithm. Specifically, at each image point an image intensity can be computed that quantifies a measure of dispersion of the image values in a particular direction with respect to their mean. Subsequently, a direction ?0(x, y) can be selected which minimizes the energy function at the given pixel (x, y). Finally, a value proportional to a local average of the input image around the point (x, y) can be chosen for the output image. In this way speckle noise can be minimized if not removed while, at the same time, maintaining the image substantially free of obvious artifacts.Type: ApplicationFiled: October 5, 2005Publication date: May 11, 2006Inventors: Giovanni Gregori, Carmen Puliafito, Robert Knighton
