Augmented Reality Medical Imaging Overlay for Anatomy Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a challenge in ensuring that medical procedures are performed on the correct patient anatomy, as errors can occur if the wrong person, appendage, or location is operated on, leading to poor outcomes.
Innovation Solution
The use of augmented reality (AR) headsets to overlay acquired medical images onto the real-world scene, combined with patient identifiers and morphometric data analysis, ensures accurate identification of patient anatomical structures by anchoring medical images to the correct anatomical points and providing augmentation tags to guide surgeons through procedures safely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional medical procedures are performed without augmented reality overlay, then the procedure can be completed with standard equipment, but the risk of operating on wrong anatomy increases and identification accuracy decreases
Solution Approach 1:
The patent combines multiple systems into a unified augmented reality display: patient identifiers, morphometric measurements, acquired medical images, and anatomical overlays are merged into a single visual interface through the AR headset, allowing simultaneous verification of multiple parameters without requiring separate viewing devices
Solution Approach 2:
The augmented reality headset acts as an intermediary between the medical professional and the patient anatomy, translating complex medical data (images, measurements, identifiers) into an intuitive visual overlay that directly annotates the relevant anatomical structures in the field of view
2Measurement precision
If multiple verification methods (patient identifiers, morphometric data, medical images) are used, then the accuracy of patient and anatomy identification improves, but the time required for verification increases
Solution Approach 1:
Patient identifiers and morphometric measurements are captured and verified before the medical procedure begins, and the corresponding medical images are pre-acquired and processed. This preliminary verification ensures that when the AR overlay is displayed during the procedure, the anatomical identification is already confirmed, reducing intra-procedure verification time
Solution Approach 2:
Multiple verification parameters (patient ID, morphometric measurements, medical images) are combined into a single integrated AR display overlay, allowing the medical professional to verify all parameters simultaneously in one glance rather than sequentially checking separate sources
Data Source
AI summary
Technology is described for augmenting medical imaging for use in a medical procedure. The method can include the operation of receiving an image of patient anatomy captured by a visual image camera during the medical procedure. An acquired medical image associated with the patient anatomy can then be retrieved. Another operation can be associating the acquired medical image to the patient anatomy. An augmentation tag associated with a location in one layer of the acquired medical image can be retrieved. A further operation can be projecting the acquired medical image and the augmentation tag using an augmented reality headset to form a single graphical view as an overlay to the patient anatomy in either 2D, 3D or holographic form.
