Patent number: 10575723Abstract: The present disclosure describes systems and method for generating surgical maps that provide a surgeon with information regarding the placement of features of interest. More particularly, the system is configured to display optical coherence tomography (OCT) images to a medical professional. The medical professional can select anatomical features, biomarkers, and other features of interest within each of the OCT images. The system can then translate the location of the features of interest within the OCT images to an en face image to generate a map of the features that the medical professional can use for surgical guidance.Type: GrantFiled: February 24, 2016Date of Patent: March 3, 2020Assignees: University of Pittsburgh—Of the Commonwealth System of Higher Education, The Regents of the University of MichiganInventors: Lawrence E.

Patent number: 9844315Abstract: The present disclosure is directed to systems and methods for normalizing an image of an eye among multiple optical coherence tomography (OCT) devices. The system can receive an OCT image and generate a normalized OCT image. The system is configured to normalize a sample density of the received image, normalize an amount of noise using a suitable noise reduction technique, normalize a distribution of signal amplitudes of the image, and then normalize a signal quality of the image. The resulting normalized image of the eye can then be used in the comparison among OCT images taken from multiple OCT devices.Type: GrantFiled: October 7, 2015Date of Patent: December 19, 2017Assignee: University of Pittsburgh—Of the Commonwealth System of Higher EducationInventors: Chieh-Li Chen, Hiroshi Ishikawa, Joel Steven Schuman, Chaim-Gadi Wollstein

Patent number: 8566384Abstract: Systems and methods are provided for efficiently counting detected events via a multiplicative group counter. An equivalent class polynomial congruent with a first of a plurality of elements comprising a multiplicative group is represented as a series of binary values. The represented polynomial is subjected to a state transition function as each event is detected, such that the series of binary values is altered to represent a new equivalent class polynomial congruent with a second of the plurality of elements of a multiplicative group. The series of binary values is decoded to determine a number of detected events recorded by the counter.Type: GrantFiled: December 13, 2007Date of Patent: October 22, 2013Assignee: Northrop Grumman Systems CorporationInventor: David Steven Schuman
