Patent number: 10354380Abstract: A method to characterize shape variations in brain ventricles during embryonic growth in mammals, the method including extracting a brain ventricle skeleton from one or more images, calculating a volume profile for the skeleton using the extracted images, partitioning the brain ventricle based on the volume profile along the skeleton, the brain ventricle being partitioned into two lateral ventricles and a main ventricle, the main ventricle being further partitioned into three sub regions, determining volume vectors of the two lateral ventricles and the three sub regions, computing a means square error between the determined computed volume vectors and a pretrained mean volume vector of embryos during different gestational stages, and classifying the embryo to the gestational stage having the lowest mean square error.Type: GrantFiled: July 9, 2018Date of Patent: July 16, 2019Assignees: Riverside Research Institute, New York UniversityInventors: Jen-wei Kuo, Jonathan Mamou, Jeffrey A.

Patent number: 10157466Abstract: A method to segment images that contain multiple objects in a nested structure including acquiring an image; defining the multiple objects by layers, each layer corresponding to one region, where a region contains an innermost object and all the objects nested within the innermost object; stacking the layers in an order of the nested structure of the multiple objects, the stack of layers having at least a top layer and a bottom layer; extending each layer with padded nodes; connecting the top layer to a sink and the bottom layer to a source, wherein each intermediate layer between the top layer and the bottom layer are connected only to the adjacent layer by undirected links; and measuring a boundary length for each layer.Type: GrantFiled: January 23, 2017Date of Patent: December 18, 2018Assignees: Riverside Research Institute, New York UniversityInventors: Jen-wei Kuo, Jonathan Mamou, Xuan Zhao, Jeffrey A.

Patent number: 9295448Abstract: A quantitative method to analyze phase-resolved, raw backscatter echo data or the envelope of phase-resolved, raw backscatter echo data to characterize vitreous inhomogeneities as they relate to normal aging and vitreo-retinal disease. The technique can be applied to 2D or 3D data acquired from the vitreous. The approach provides an objective end value to characterize the vitreous and provide a tool for early diagnosis, monitoring and planning treatment of vitreo-retinal diseases.Type: GrantFiled: March 13, 2014Date of Patent: March 29, 2016Assignees: Riverside Research Institute, The Trustees of Columbia University in the City of New YorkInventors: Jeffrey A.

Publication number: 20150196279Abstract: A method to increase the image formation speed in an annular-array digital ultrasound system consisting of N elements with a plurality of transmit and receive channels. Selectively dropping one or more transmit or receive channels during image formation reduces the amount of data needed to form an image, thus increasing the image formation frame rate through faster scan speeds or reducing the amount of digitized data required to process an image. The improved frame rate does result in some reduction in resolution, SNR and potentially DOF, but these drawbacks can be mitigated by synthetically recovering missing transmit-to-receive data pairs.Type: ApplicationFiled: March 17, 2015Publication date: July 16, 2015Applicant: RIVERSIDE RESEARCH INSTITUTEInventors: Jeffrey A. Ketterling, Erwan Filoux

Publication number: 20080228074Abstract: The present invention provides a system and method for measuring acoustic pressure at multiple locations simultaneously. An array transducer device is prepared where a polyimide film is bonded to a piezopolymer membrane using a non-conductive epoxy. The polyimide is etched with a linear array pattern having array elements, connection pads and electrical connections connecting the array elements to the connection pads. The array pattern is electronically accessed by linking traces of a customized printed circuit board to the electrical connections of the array pattern via ZIF connectors.Type: ApplicationFiled: March 11, 2008Publication date: September 18, 2008Inventor: Jeffrey A.
