Patent number: 12229924Abstract: A method for generating a subtraction image for digital subtraction angiography to reduce noise and movement artifacts. Obtaining a plurality of mask images of an object takes place before administering a contrast agent into the object and obtaining a map of the object after administering a contrast agent into the object.

Patent number: 10755408Abstract: A medical information processing system according to an embodiment includes processing circuitry. The processing circuitry is configured to identify the position of a tissue from first medical image data represented by an image of a target site acquired before the tissue in the target site was collected and to obtain an image feature value of the tissue. The processing circuitry is configured to obtain an examination result of a pathological examination performed on the tissue. The processing circuitry is configured to bring the image feature value of the tissue into association with the examination result of the pathological examination.Type: GrantFiled: May 7, 2018Date of Patent: August 25, 2020Assignee: Canon Medical Systems CorporationInventors: Yasuo Sakurai, Masahiro Ozaki, Atsuko Sugiyama, Seiko Yoshimura, Keisuke Hashimoto

Patent number: 10705245Abstract: Imaging systems and methods are provided for detecting objects that may be hidden under clothing, ingested, inserted, or otherwise concealed on or in a person's body. An imaging assembly, e.g., X-ray source and X-ray detector, and mechanisms, e.g., a translational mechanism for vertically moving the imaging assembly, may be configured to reduce the overall form factor of such imaging systems, while still retaining an ability to perform full/complete imaging of a subject.Type: GrantFiled: September 17, 2019Date of Patent: July 7, 2020Assignee: TEK84 INC.Inventor: Steven Winn Smith

Patent number: 10687774Abstract: A method for representing a blood vessel including a thrombosed section of the blood vessel in a patient is provided. The method includes capturing a first volume data set after administration of a contrast agent, locating a proximal and/or distal end of the thrombosed section of the blood vessel with the aid of the first volume data set, and defining a data capture area for a second volume data set based on the proximal and/or distal end of the thrombosed section of the blood vessel that has been located. The method also includes capturing the second volume data set, segmenting the thrombosed section of the blood vessel from the second volume data set, capturing fluoroscopic images, and superimposing the segmented thrombosed section of the blood vessel with the fluoroscopic images.Type: GrantFiled: March 14, 2015Date of Patent: June 23, 2020Assignee: Siemens AktiengesellschaftInventor: Stefan Lautenschläger

Patent number: 10578753Abstract: An apparatus, system, and method involving one or more sparse detectors are provided. A sparse detector may include an array of scintillator crystals generating scintillation in response to radiation and an array of photodetectors generating an electrical signal in response to the scintillation. A portion of the scintillator crystals may be spaced apart by substituents or gaps. The distribution of the substitutes or gaps may be according to a sparsity rule. At least a portion of the array of photodetectors may be coupled to the array of scintillator crystals. An imaging system including an apparatus that may include one or more sparse detectors is provided. The imaging system may include a processor to process the imaging data acquired by the apparatus or system including the one or more sparse detectors. The method may include preprocess the acquired image data and produce images by image reconstruction.Type: GrantFiled: June 21, 2019Date of Patent: March 3, 2020Assignee: SHANGHAI UNITED IMAGING HEALTHCARE CO., LTD.Inventors: Hongdi Li, Shaohui An, Yun Dong, Yang Lv, Lingzhi Hu, Jun Bao

Patent number: 10528566Abstract: In one aspect, there is provided a system configured to receive time series data collected by a first sensor. The time series data collected by the first sensor can be stored in a first data array associated with the first sensor. The first data array can stored proximate to a second data array that includes time series data collected by a second sensor. The first data array can be stored proximate to the second data array based on the first and second sensor being in a same sensor group. A query can be received to perform a processing algorithm on a subset of time series data. The subset can be generated by retrieving the first and second data array. The query can be executed by applying the processing algorithm to the subset of time series data. Related methods and articles of manufacture are also provided.Type: GrantFiled: June 30, 2017Date of Patent: January 7, 2020Assignee: REFERENTIA SYSTEMS, INC.Inventors: Matthew Shawver, Anthony Commendador, Wenyi Zhou
