Wearable Surgical Imaging Display for Real-Time Multimodal Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical navigation systems lack real-time imaging updates and comprehensive anatomical information, while intra-operative imaging provides limited views, and pathology-based techniques are time-consuming and incomplete, necessitating a system that integrates pre-operative, intra-operative, and in-vivo imaging/sensing for immersive 3D guidance.
Innovation Solution
A wearable imaging and display system that simultaneously displays pre-operative surgical navigation images, real-time intra-operative images, and in-vivo microscopy data, using a detector, computing unit, and communication interface for stereoscopic viewing and data sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional surgical navigation using pre-operative images is used, then global anatomical information is provided, but real-time imaging updates and tissue deformation accommodation are unable
Solution Approach 1:
The patent merges pre-operative surgical navigation images with real-time intra-operative images and in-vivo microscopy images into a single integrated display system. The wearable display simultaneously presents multiple image types and data streams, allowing surgeons to view global anatomical context alongside real-time surgical field information and cellular-level pathology without switching between separate systems
Solution Approach 2:
The patent adds a temporal dimension by integrating images captured at different time points (pre-operative, intra-operative, real-time) into a unified spatial display. The system co-registers images across different time frames and scales, enabling surgeons to perceive historical anatomical context alongside current surgical status in a single immersive view
2Loss of time
If intra-operative imaging is used, then real-time imaging updates are provided, but limited field of view and comprehensive anatomical information are unable
Solution Approach 1:
The system combines intra-operative imaging data with pre-operative surgical navigation images and in-vivo microscopy images in a unified wearable display. This integration allows the limited field of view from intra-operative imaging to be contextualized within the broader anatomical framework from pre-operative scans, providing both real-time updates and comprehensive anatomical information simultaneously
3Measurement precision
If pathology-based techniques are used, then in-vivo microscopy imaging is provided, but time-consuming and incomplete sampling are unable
Solution Approach 1:
The system performs preliminary imaging and documentation of surgical sites using in-vivo microscopy before formal pathology analysis. By capturing and storing high-resolution cellular images in real-time during surgery, the system creates a preliminary record that reduces the need for extensive post-operative pathology sampling and accelerates diagnostic turnaround time
4Adaptability or versatility
If separate imaging systems are used for surgical navigation, intra-operative imaging, and pathology, then specialized functionality is provided, but system complexity and integration difficulty increase
Solution Approach 1:
The wearable display system is designed as a universal platform capable of displaying multiple types of medical images and data streams simultaneously. It integrates surgical navigation images, intra-operative imaging, in-vivo microscopy, and pathology reports into a single adaptive interface that can present diverse information types without requiring separate dedicated display systems for each modality

AI summary
An imaging and display system for guiding medical interventions includes a wearable display, such as a goggle display, for viewing by a user. The display presents a composite, or combined image that includes pre-operative surgical navigation images, intraoperative images, and in-vivo microscopy images or sensing data. The pre-operative images are acquired from scanners, such as MRI and CT scanners, while the intra-operative images are acquired in real-time from a camera system carried by the goggle display for imaging the patient being treated so as to acquire intraoperative images, such as fluorescence images. A probe, such as a microscopy probe or a sensing probe, is used to acquire in-vivo imaging/sensing data from the patient. Additionally, the intra-operative and in-vivo images are acquired using tracking and registration techniques to align them with the pre-operative image and the patient to form a composite image for display by the goggle display.
