Solution Overview
Problem
During surgery, the repositioning of medical image capture devices can be delayed and risky due to complex surgical scenes with multiple moving components, leading to suboptimal viewpoints if improved positions are not readily identified by the surgeon.
Innovation Solution
A system and method for controlling medical image capture devices that receive images and additional scene information to determine candidate viewpoints, provide simulated images of these viewpoints, and adjust the device to select the optimal view without physical repositioning, using circuitry and a computer program product to optimize camera system viewpoints during surgery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the medical image capture device is repositioned during surgery to improve viewpoint, then the image quality and surgical view are improved, but the surgical procedure is delayed and patient risk increases
Solution Approach 1:
The system performs preliminary actions by pre-calculating and storing optimal viewpoint positions and simulated images before surgery begins. During surgery, the system simply retrieves and displays these pre-computed viewpoints, eliminating the need for time-consuming real-time calculations and physical repositioning of the camera device.
Solution Approach 2:
The system creates virtual copies of the surgical scene from different viewpoints using simulated images generated by the image generation circuitry. These virtual viewpoint copies allow surgeons to evaluate alternative camera positions without physically moving the actual image capture device, thus avoiding surgical delays.
2Measurement precision
If the medical image capture device is repositioned during surgery to improve viewpoint, then the image quality and surgical view are improved, but patient safety risk increases
Solution Approach 1:
The system creates virtual copies of the surgical scene from different viewpoints using simulated images. These virtual viewpoint representations allow surgeons to assess alternative camera positions and select optimal viewpoints without physically manipulating the camera device during surgery, thereby eliminating repositioning-related safety risks.
Solution Approach 2:
The system introduces an intermediary layer of simulated viewpoint images between the actual camera device and the surgeon's decision-making process. This intermediary allows evaluation of multiple virtual positions without requiring physical camera movement, thus protecting patient safety while still enabling viewpoint optimization.
3Measurement precision
If the surgeon manually identifies optimal camera positions, then the surgical view can be optimized, but time is lost and suboptimal viewpoints may be tolerated
Solution Approach 1:
The system performs self-service by automatically calculating, generating, and presenting multiple candidate viewpoints to the surgeon without requiring manual intervention for viewpoint identification. The determination circuitry autonomously processes surgical scene data and generates optimized viewpoint recommendations, freeing the surgeon from time-consuming manual assessment.
Solution Approach 2:
The system replaces the mechanical process of manual camera repositioning and visual assessment with an automated computational system. The image generation circuitry and determination circuitry substitute for the surgeon's manual viewpoint evaluation, rapidly generating multiple candidate viewpoints for selection without physical camera movement.
4Adaptability or versatility
If multiple candidate viewpoints are evaluated, then the optimal surgical view can be selected, but the system complexity increases
Solution Approach 1:
The system performs viewpoint calculations and simulated image generation as preliminary actions before surgery. By pre-computing multiple candidate viewpoints and storing them for rapid retrieval during surgery, the system provides viewpoint selection flexibility without requiring complex real-time processing that would increase operational system complexity.
