Patent number: 11276500Abstract: Methods, systems, and computer readable media for utilizing brain structural characteristics for predicting a diagnosis of a neurobehavioral disorder are disclosed. One method for utilizing brain structural characteristics for predicting a diagnosis of a neurobehavioral disorder includes receiving brain imaging data for a human subject of at least one first age. The method also includes determining, from the brain imaging data, measurements of brain structural characteristics of the human subject and inputting the brain structural characteristics into a model that predicts, using the measurements of the brain structural characteristics, a diagnosis of a neurobehavioral disorder at a second age greater than the at least one first age.Type: GrantFiled: December 28, 2018Date of Patent: March 15, 2022Assignees: THE UNIVERSITY OF NORTH CAROLINA AT CHAPEL HILL, COLLEGE OF CHARLESTON, THE ROYAL INSTITUTION FOR THE ADVANCEMENT OF LEARNING/MCGILL UNIVERSITYInventors: Martin Andreas Styner, Sun Hyung Kim, Donald Louis Collins, Vladimir S.

Patent number: 11151722Abstract: A computer-implemented method, an apparatus, and a system for estimating synthetic values of quantitative metrics are provided. They involve calculating new, more accurate boundaries using a classifier based on local intensity and spatial estimators, for the segmentation mask provided by a non-local means patch-based segmentation in a test image, and estimating for the pixels of interest at least one synthetic value of a quantitative metric using a given value of the quantitative metric assigned to the reference images and the boundaries. The method, apparatus, and system provide the advantage of generating synthetic values directly comparable against known values for given subjects or against predetermined scales for diagnostic or prognostic purposes. In the specific case of Alzheimer's disease, the invention stretches the predictive range up to two full decades, which constitutes a significant advance in the field of medical diagnostics.Type: GrantFiled: July 22, 2016Date of Patent: October 19, 2021Inventors: Simon Duchesne, Pierre Gravel, Louis Collins

Publication number: 20210317645Abstract: A plumbing trap assembly for integrating a plumbing trap into a variety of plumbing geometries includes a plumbing trap that has an inlet and an outlet for plumbing into an existing sewer system of a building. The plumbing trap is curved between the inlet and the outlet to trap water for inhibiting back flow of sewer gasses through the plumbing trap. The plumbing trap has a plurality of threaded sections thereon. The threaded sections are spaced apart from other thereby facilitating the plumbing trap to be cut between a selected pair of the threaded sections. In this way the plumbing trap has an adjustable length to facilitate the plumbing trap to be integrated into a variety of plumbing geometries.Type: ApplicationFiled: April 9, 2020Publication date: October 14, 2021Inventors: Louis Collins, Yvonne Collins

Patent number: 7751602Abstract: A method of classifying a test subject comprises collecting imaging data for a plurality of training subjects, control subjects and a test subject. An intensity volume of interest (VOI) and a morphological VOI are selected from said imaging data. Training intensity data and morphological data are calculated for the intensity and spatial VOI. A statistical model can then be created based on the training intensity data and training spatial data to provide a universe of subjects. Control intensity data and spatial data are also calculated for the intensity and spatial VOI. A classifier can then be built dividing the universe into at least two regions. The test subject data can then be applied to the classifier to provide a determination of whether the test subject falls within the first region or the second region. The condition can be a neurological disease state such as temporal lobe epilepsy or Alzheimer's dementia.Type: GrantFiled: November 18, 2004Date of Patent: July 6, 2010Assignee: McGill UniversityInventors: Louis Collins, Simon Duchesne
