Publication number: 20220409281Abstract: A computing device having a first processor configured to receive three-dimensional imaging data acquired by an imaging system, the three-dimensional imaging data being from ahead of a subject. The first processor can be configured to determine vascular structures from the three-dimensional imaging data, generate a three-dimensional model of the head of the subject from the three-dimensional imaging data, the three-dimensional model of the head including a three-dimensional model of the vascular structures and a three-dimensional model of a portion of a frontal horn of the subject, determine an entry point on the three-dimensional model of the head of the subject, determine a plurality of trajectories, each trajectory intersecting the three-dimensional model of the portion of the frontal horn and does not intersect the three-dimensional model of the vascular structures, and each trajectory is linear, and select a final trajectory from the plurality of trajectories.Type: ApplicationFiled: November 23, 2020Publication date: December 29, 2022Inventors: William B. Gormley, Junichi Tokuda, Faith C. Robertson, Paola Calvachi Prieto, Franklin King, Steve Pieper

Publication number: 20210153764Abstract: The present disclosure is directed to systems and methods for generating images using short tau inversion recovery, ultrashort echo time (STIR-UTE) MRI sequences. The STIR-UTE MRI sequences can be used to generate images that can differentiate between regions that are at temperatures that are either lethal or non-lethal to cell life. Thus, these sequences can be beneficial for implementations such as in monitoring cryoablation procedures.Type: ApplicationFiled: November 18, 2020Publication date: May 27, 2021Inventors: Junichi Tokuda, Qun Wang, Kemal Tuncali, Ravi Teja Seethamraju, Clare M. Tempany, Ehud J. Schmidt

Patent number: 10420626Abstract: Exemplary methods, apparatus, and systems are provided for automated detection and registration of medical images using fiducial markers and processing algorithms. By either clustering fiducial markers having a different number, size, shape, configuration, or material property or by using fiducial markers arranged in a ring shape, wherein their arrangement is asymmetric, and then applying a feature extraction to extract the fiducial marker objects, and registering the fiducial marker objects with a model of the fiducial frame, automatic registration can be achieved.Type: GrantFiled: June 30, 2015Date of Patent: September 24, 2019Assignees: Canon U.S.A., Inc., The Brigham and Women's Hospital, Inc.Inventors: Junichi Tokuda, Nobuhiko Hata, Takahisa Kato, Brian Ninni, Laurent Chauvin

Patent number: 9993211Abstract: A system and method for automatic registration of medical images includes accessing image data of a subject and plurality of elongated fiducial markers arranged in an asymmetrical orientation and analyzing the image data to detect the elongated fiducial markers by applying a line filter to treat the elongated fiducial markers as lines within the image data. The system and method also includes matching the elongated fiducial markers within the image data to a model of the elongated fiducial markers, registering the image data with a coordinate system based on the matching, and generating a report indicating at least the registered image data.Type: GrantFiled: September 19, 2014Date of Patent: June 12, 2018Assignee: The Brigham and Women's Hospital, Inc.Inventors: Junichi Tokuda, Sang-Eun Song, Nobuhiko Hata
