Patent number: 11439362Abstract: A method and system acquiring, processing and displaying breast ultrasound images in a way that makes breast ultrasound screening more practical and thus more widely used, and reduces the occurrence of missing cancers in screening and diagnosis, using automated scanning of chestwardly compressed breasts with ultrasound. Enhanced, whole-breast navigator overview images are produced from scanning breasts with ultrasound that emphasize abnormalities in the breast while excluding obscuring influences of non-breast structures, particularly those external to the breast such as ribs and chest wall, and differentiating between likely malignant and likely benign abnormalities and otherwise enhancing the navigator overview image and other images, thereby reducing the time to read, screen, and/or diagnose to practical time limits and also reduce screening or diagnostic errors.Type: GrantFiled: October 29, 2019Date of Patent: September 13, 2022Assignee: QView Medical, Inc.Inventors: Wei Zhang, Shih-Ping Wang, Alexander Schneider, Harlan Romsdahl, Thomas Neff

Patent number: 10664969Abstract: Targeting of a lesion which is performed by a stereoscopic biopsy device or the like is performed simply and highly accurately. Designation of a predetermined position in the stereoscopic image is received to acquire position information when a stereoscopic image is displayed, radiological images of radiographing directions are displayed as two-dimensional images, a mark based on the position information, which is designated in the stereoscopic image, is displayed in the two-dimensional images, designation of a predetermined position in the two-dimensional images is further received to acquire the position information after the mark is displayed.Type: GrantFiled: April 19, 2017Date of Patent: May 26, 2020Assignee: FUJIFILM CorporationInventors: Hiroki Nakayama, Akira Hasegawa, Harlan Romsdahl

Publication number: 20080050020Abstract: An algorithm is quickly scans a digital image volume to detect density nodules. A first stage is based on a transform to quickly highlight regions requiring further processing. The first stage operates with somewhat lower sensitivity than is possible with more detailed analyses, but operates to highlight regions for further analysis and processing. The transform dynamically adapts to various nodule sizes through the use of radial zones. A second stage uses a detailed gradient distribution analysis that only operates on voxels that pass a threshold of the first stage.Type: ApplicationFiled: July 12, 2007Publication date: February 28, 2008Inventors: Harlan Romsdahl, Wei Zhang, Alexander Schneider

Publication number: 20070003124Abstract: A computer-aided diagnostic method and system provide image annotation information that can include an assessment of the probability, likelihood or predictive value of detected or identified suspected abnormalities as an additional aid to the radiologist. More specifically, probability values, in numerical form and/or analog form, are added to the locational markers of the detected and suspected abnormalities. The task of a physician using such a system as disclosed is believed to be made easier by displaying markers representing different regions of interest.Type: ApplicationFiled: May 22, 2006Publication date: January 4, 2007Inventors: Susan Wood, Heidi Zhang, Anat Caspi, Takeshi Doi, Harlan Romsdahl
