Surgical Timing Signal Display for Lesion Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image-guided interventional procedures, radiologists face challenges in synchronizing needle insertion with patient breathing movements, as existing methods require visual attention on both the target lesion and a separate timing signal display, which is not intuitive.
Innovation Solution
A system that extracts a timing signal based on sensor positions using real-time tracking, duplicates the target lesion for visual feedback, and adjusts color and blurriness on a display screen to indicate optimal insertion time, allowing physicians to focus on the lesion without diverting attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a separate timing signal display is used, then the timing information is provided, but the physician's visual attention is divided between the target lesion and the timing signal
Solution Approach 1:
The patent merges the timing signal information with the target lesion display by superimposing visual indicators (such as color changes, icons, or graphical overlays) directly on or near the lesion image. This integration allows the physician to perceive timing cues without shifting visual focus to a separate display location, thereby resolving the contradiction between providing timing information and maintaining ease of visual operation.
2Measurement precision
If real-time tracking sensors are used, then the timing accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent introduces an intermediary processing system that receives data from multiple real-time tracking sensors and converts it into simplified visual timing indicators displayed on the existing imaging interface. This intermediary layer manages the complexity of sensor integration and data processing while presenting simplified, intuitive timing information to the physician, thereby achieving high timing accuracy without proportionally increasing operational complexity.
3Ease of operation
If multiple lesion display objects are duplicated, then the timing visualization is enhanced, but the information display becomes more complex
Solution Approach 1:
The patent applies local quality by differentiating the visual properties (such as color, transparency, or size) of duplicated lesion display objects based on their temporal significance. Instead of uniformly displaying all duplicated objects, the system varies their visual characteristics to highlight the most relevant timing information, thereby enhancing visual feedback while managing display complexity through selective emphasis rather than uniform detail.

AI summary
The present teaching relates to surgical procedure assistance. In one example, a plurality of similarity measures are determined between a first set of positions and a plurality of second sets of positions, respectively. The first set of positions is obtained with respect to a plurality of sensors coupled with a patient in an image captured prior to a surgical procedure. The plurality of second sets of positions are obtained from the plurality of sensors and change in accordance with movement of the patient. A target lesion is segmented in the image captured prior to the surgical procedure to obtain a lesion display object. The lesion display object is duplicated to generate a plurality of lesion display objects. The plurality of lesion display objects are presented on a display screen so that a distance between the plurality of lesion display objects changes in accordance with the plurality of the similarity measures.
