Adaptive Image Acquisition for Surgical Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inaccurate registration between preoperative and intraoperative images during surgical procedures due to patient movement and equipment shifts, leading to potential inaccuracies in surgical instrument location information.
Innovation Solution
A computing device that obtains a guide image, compares it with intraoperative images, and adjusts the registration by identifying matching regions and combining images to maintain accurate tracking of surgical instruments without interrupting the surgical procedure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional registration correction methods are used, then registration accuracy is improved, but surgical procedure time is increased due to interruptions
Solution Approach 1:
The system performs automatic image registration and accuracy assessment without requiring surgeon intervention. The computing device autonomously compares guide images with intraoperative images, evaluates registration accuracy, and triggers additional image acquisition only when needed, eliminating the need for manual correction interruptions during surgery
Solution Approach 2:
The system continuously monitors registration accuracy by comparing guide images with newly acquired intraoperative images. When registration deviation exceeds a threshold, the system automatically requests additional images and adjusts registration, providing real-time feedback without interrupting the surgical flow
2Productivity
If registration correction is omitted to maintain continuous surgical procedure, then surgical procedure time is reduced, but registration accuracy deteriorates leading to incorrect surgical instrument location information
Solution Approach 1:
The system autonomously detects registration degradation by comparing sequential intraoperative images with guide images and automatically initiates correction procedures when accuracy thresholds are breached, maintaining precision without requiring surgeon awareness or intervention
Solution Approach 2:
The registration monitoring and correction process operates continuously in the background throughout the surgical procedure, ensuring uninterrupted surgical workflow while maintaining accurate registration through automated image comparison and adaptive adjustment

AI summary
A method of adaptive image acquisition includes obtaining a guide image of patient tissue; receiving an intraoperative image of a portion of the patient tissue from an imaging instrument; and storing the intraoperative image. The method includes comparing the intraoperative image with the guide image to identify at least one region of the guide image matching the intraoperative image; and determining whether the at least one region identified meets at least one accuracy criterion. When the at least one region meets the at least one accuracy criterion, the guide image is rendered with an indication of the at least one region on a display. When the at least one region does not meet the at least one accuracy criterion, the method includes receiving and storing a further intraoperative image; combining the further intraoperative image with the intraoperative image; and repeating the comparing and determining.
