Patent number: 12245895Abstract: A method and system for two-dimensional shear wave elastography imaging (SWEI) that acquires B-mode ultrasound image of a region, selects an area of the B-mode image, automatically acquires two-dimensional shear wave elastography imaging data related to the selected area, and displays elasticity/velocity map on the selected area and optionally a reliability map. An algorithm takes as input one or combination of data sets selected from B-mode raw data or B-mode image data or elasticity/velocity map or reliability map or—raw two-dimensional shear wave elastography imaging data inside selected area, or two-dimensional shear wave elastography imaging data at an intermediate stage of processing like displacement curves over time or their peak features, and outputs the 2D coordinate of measure ROI center. Measure ROI overlapped on the B-mode image and/or on the elasticity map and/or on the reliability map is displayed. An elasticity parameter inside the measure ROI is computed, optionally weighted, and displayed.Type: GrantFiled: October 4, 2021Date of Patent: March 11, 2025Assignee: Esaote S.p.A.Inventors: Stefano De Beni, Marco Crocco

Publication number: 20230281837Abstract: A tracker-less method is provided for registering images acquired with different modalities for generating fusion images from registered images acquired with different modalities. The method acquires a sequence of ultrasound images by interlacing wide, high depth ultrasound scans to zoomed ultrasound scans; and registers image data obtained from the high-depth ultrasound scans with image data of the same anatomical region acquired with a different modality and determining registration data. The image data obtained from the high-depth ultrasound scan and/or the image data acquired with the different modality is not displayed to the user. Image data acquired by the zoomed ultrasound scan is registered with the zoomed image data obtained with the different modality by applying the registration data to the image data acquired by the zoomed ultrasound scans. Registered image data is combined with the zoomed image data obtained with the different modality and the combined or image data is displayed.Type: ApplicationFiled: February 28, 2023Publication date: September 7, 2023Inventors: Stefano De Beni, Luca Zini, Marco Crocco, Sara Traversini
