Patent number: 11941768Abstract: Methods and systems for alignment of a subject for medical imaging are disclosed, and involve capturing an image of an anatomical region comprising a target tissue and determining, based on the image and based on a reference image, that a current alignment of the image capture device is aligned with a predefined alignment. The determination is performed before initiating capturing of a time series of fluorescence medical images from fluorescence emission. In response to the determining that the current alignment is aligned with the predefined alignment, capturing of the time series of fluorescence medical images from the fluorescence emission is initiated.Type: GrantFiled: January 30, 2023Date of Patent: March 26, 2024Assignee: Stryker CorporationInventors: Jorgen Walle-Jensen, Lina Gurevich, Gregory Vincent Browne

Patent number: 11715205Abstract: Methods and systems for characterizing tissue of a subject are disclosed. The method includes retrieving a time series of angiography images of tissue of a subject, defining a plurality of calculation regions, generating a time-intensity curve for each respective calculation region, calculating a rank value for each respective calculation region based on one or more parameters derived from the time-intensity curve; and generating a viewable image in which on the image position of each calculation region an indication is provided of the calculated rank value for that calculation region. Also disclosed are methods and systems for generating first and second time-intensity curves for respective first and second calculation regions, calculating first and second rank values for the respective calculation regions based on first and second pluralities of parameters selected to approximate the respective time-intensity curves, and generating a spatial map of the first and second calculated rank values.Type: GrantFiled: September 18, 2020Date of Patent: August 1, 2023Assignee: Stryker European Operations LimitedInventors: Lina Gurevich, Jorgen Walle-Jensen

Publication number: 20220151495Abstract: Disclosed herein are systems and methods that can assess whether there is an issue with tissue perfusion, which can help a clinician better predict any surgical complications that may arise. Fluorescence images of the tissue of a subject can continuously be observed until a portion of the tissue that first perfused with blood containing one or more fluorescent agents is at peak fluorescence. Any areas of the tissue from the fluorescence images that remain dark can be further observed until these areas of concern show their first sign of fluorescence. The time it takes for these areas of concern to show their first signs of fluorescence since the first onset of fluorescence in the tissue can be referred to as the relative onset fluorescence delay. If the relative onset fluorescence delay time is greater than a predetermined threshold, the clinician can alter or change the surgical plan.Type: ApplicationFiled: November 15, 2021Publication date: May 19, 2022Applicant: Stryker CorporationInventor: Jørgen WALLE-JENSEN
