Patent number: 11378396Abstract: A system uses range and Doppler velocity measurements from a lidar system and images from a video system to estimate a six degree-of-freedom trajectory of a target. The system estimates this trajectory in two stages: a first stage in which the range and Doppler measurements from the lidar system along with various feature measurements obtained from the images from the video system are used to estimate first stage motion aspects of the target (i.e., the trajectory of the target); and a second stage in which the images from the video system and the first stage motion aspects of the target are used to estimate second stage motion aspects of the target. Once the second stage motion aspects of the target are estimated, a three-dimensional image of the target may be generated.Type: GrantFiled: September 28, 2019Date of Patent: July 5, 2022Assignee: Aeva, Inc.Inventors: Richard L. Sebastian, Anatoley T. Zheleznyak

Patent number: 11379984Abstract: Systems and methods for processing electronic images from a medical device comprise receiving a first image frame and a second image frame from a medical device, and determining a region of interest by subtracting the first image frame from the second image frame, the region of interest corresponding to a visual obstruction in the first image frame and/or second image frame. Image processing may be applied to the first image frame and/or second image frame based on a comparison between a first area of the first image frame corresponding to the region of interest and a second area of the second image frame corresponding to the region of interest, and the first image frame and/or second image frame may be provided for display to a user.Type: GrantFiled: August 21, 2020Date of Patent: July 5, 2022Assignee: Boston Scientific Scimed, Inc.Inventors: Longquan Chen, Niraj P. Rauniyar, Evan Gyllenhaal

Patent number: 11364005Abstract: A method of performing a procedure on a breast of a patient includes compressing the breast of the patient with a paddle of an imaging system and performing an initial imaging procedure on the breast of the patient. The initial imaging procedure includes imaging the breast with an x-ray source at a first energy to obtain a first image and a second energy to obtain a second image. A composite image is generated from the first image and the second image and displayed. A region of interest on the composite image is targeted and a biopsy is performed.Type: GrantFiled: October 23, 2014Date of Patent: June 21, 2022Assignee: Hologic, Inc.Inventors: Andrew P. Smith, Julian Marshall

Patent number: 11341672Abstract: A method and a device are for detecting an anatomical feature of a section of a blood vessel. In an embodiment, the device includes a first interface embodied to receive a medical image data record, including a region of an anatomy of a patient to be examined, which has the section of a blood vessel; a first computing unit, embodied to apply a first algorithm pretrained on an anatomical feature for detecting the anatomical feature based upon the medical image data record; and a second interface embodied to provide an item of information based upon the detection of the anatomical feature. The anatomical feature includes a change in caliber of a blood vessel. Further, the presence of the anatomical feature is indicative of vascular pulmonary disease, in particular of chronic thromboembolic pulmonary hypertension.Type: GrantFiled: December 11, 2019Date of Patent: May 24, 2022Assignee: SIEMENS HEALTHCARE GMBHInventor: Sebastian Schmidt

Patent number: 11334998Abstract: According to one embodiment, a medical image processing apparatus includes processing circuitry. The processing circuitry specifies, before position alignment between a first X-ray image and a second X-ray image which is acquired with a device inserted, a device area candidate in the second X-ray image as a candidate of an area where the device appears. The processing circuitry performs the position alignment using first processing of removing the specified device area candidate or second processing of reducing a contribution of the specified device area candidate.Type: GrantFiled: April 21, 2020Date of Patent: May 17, 2022Assignee: CANON MEDICAL SYSTEMS CORPORATIONInventors: Hirona Oikawa, Shingo Abe, Kunio Shiraishi, Toshiya Waku, Shumpei Ohashi, Akihito Takahashi, Saki Hashimoto, Jumpei Ogasawara

Patent number: 11288789Abstract: An image processing system and method obtains one or more source images in which a damaged vehicle is represented, and performs one or more image processing techniques on the obtained images to determine, predict, estimate, and/or detect damage that has occurred at various locations on the vehicle. Specifically, the system/method generates damage parameter values based on the image-processed images, where each value corresponds to damage at a particular location on the vehicle. The image processing techniques may include generating a composite image of the damaged vehicle, aligning and/or isolating the image, applying convolutional neural network techniques to the image to generate the damage parameter values, etc. Based on the generated values, the image processing system/method determines, predicts, estimates, and/or selects a set of parts that are needed to repair the vehicle and, in some embodiments, orders the parts needed to repair the vehicle.Type: GrantFiled: May 20, 2016Date of Patent: March 29, 2022Assignee: CCC INTELLIGENT SOLUTIONS INC.Inventors: Ke Chen, John L.
