Surgical Navigation Superimposed Image Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical navigation systems face challenges in accurately and efficiently identifying anatomical structures, leading to increased operating time, complications, and errors in surgical instrument placement, which can result in additional procedures and patient harm due to excessive radiographic scanning.
Innovation Solution
A method and system that selects and adjusts two-dimensional images from a three-dimensional image to form superimposed images along specific viewing directions, allowing for precise guidance of virtual surgical instruments, thereby enhancing the visibility of anatomical structures like the pedicle of a spinal vertebra, using techniques such as CT scans for osseous structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional radiographic scans are obtained to improve anatomical structure visibility, then the clarity of anatomical structures improves, but the patient's X-ray exposure increases and operating time increases
Solution Approach 1:
The patent transforms three-dimensional CT scan data into multiple two-dimensional superimposed images viewed from different directions (coronal, sagittal, axial planes). This dimensional transformation allows surgeons to visualize anatomical structures clearly without requiring additional three-dimensional scans, thereby reducing patient X-ray exposure while maintaining measurement precision.
Solution Approach 2:
The system pre-processes three-dimensional CT images into two-dimensional superimposed images before surgery. By preparing these enhanced visualizations in advance, the system eliminates the need for additional intraoperative radiographic scans, reducing both patient exposure and operating time while ensuring clear anatomical structure visibility when needed.

Solution Approach 2:
The patent creates two-dimensional superimposed image copies from the original three-dimensional CT scan data. These copied images provide clear anatomical structure visualization without requiring additional original scans, thereby reducing operating time and patient exposure while maintaining measurement precision.
3Ease of operation
If conventional radiographic images are used to locate anatomical structures, then the surgical navigation process is simple, but the accuracy of anatomical structure identification decreases

AI summary
A surgical navigation method includes selecting one or more two-dimensional images from a three-dimensional image. The method further includes adjusting a portion of the two-dimensional images along a viewing direction. The method also includes superimposing the portion of the two-dimensional images along the viewing direction to form a two-dimensional superimposed image. The method further incudes guiding movement of a virtual surgical instrument into the two-dimensional superimposed image.
