Robotic Medical Object Positioning for Imaging Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current interventional medical procedures require high personnel and operating stress due to the manual tracking of imaging systems, leading to excessive exposure to X-ray radiation for both medical operators and examination objects during procedures involving vessel systems.
Innovation Solution
A medical imaging system with a processing unit that determines the instantaneous position of a medical object and specifies a target position relative to a mapping region, generating control signals for robotic movement to guide the object accurately, thereby reducing manual intervention and radiation exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual tracking of imaging systems is used, then the medical object can be positioned and imaged, but operator stress and radiation exposure increase significantly
Solution Approach 1:
The imaging system automatically tracks the medical object by detecting its position through image data processing and autonomously adjusting imaging parameters and beam positioning without requiring manual intervention from the operator
Solution Approach 2:
The patent replaces manual mechanical tracking operations with an automated computer-controlled imaging system that uses image processing algorithms to detect and track the medical object's position and automatically adjusts imaging parameters
2Measurement precision
If manual guidance of ultrasonic head is used, then the correct vessel view can be obtained, but personnel requirements and operating stress increase
Solution Approach 1:
The ultrasonic imaging system automatically adjusts the ultrasonic head position and imaging parameters by processing image data to detect the medical object and autonomously optimizing the vessel view without requiring manual guidance from the operator
Solution Approach 2:
The system continuously processes image data to detect the medical object's position and uses this feedback to automatically adjust imaging parameters and beam positioning, creating a closed-loop control system that maintains optimal imaging conditions
3Object-affected harmful factors
If robotic positioning is implemented, then radiation exposure is reduced, but system complexity increases
Solution Approach 1:
The automated imaging system performs multiple functions including automatic object detection, position tracking, imaging parameter optimization, and beam positioning control within a single integrated platform, reducing the need for separate manual control systems
Solution Approach 2:
The patent replaces complex manual mechanical positioning systems with an automated computer-controlled system that uses image processing and algorithm-based control to achieve precise positioning with reduced operational complexity

AI summary
A medical imaging system includes a medical imaging device to map a mapping region inside an examination object, the medical imaging device being designed such that a location of the mapping region is changable in respect of the examination object; and a processing device, including a data interface, to robotically position a medical object inside the examination object, via a movement device. In an embodiment, the processing device is configured to determine an instantaneous position of the medical object; specify a target position for the medical object, the target position being defined relative to the mapping region; determine one or more control signals, configured to cause a movement of the medical object via the movement device from the instantaneous position to the target position; and provide the one or more control signals, via the data interface, to the movement device.
