Automated Imaging System Positioning with 3D Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual positioning of imaging devices during medical procedures is time-consuming and exposes patients to excessive radiation due to the need for trial and adjustment based on two-dimensional images.
Innovation Solution
An imaging system with a moveable source and detector that can be automatically positioned relative to the subject using a controller and tracking systems, allowing for precise alignment and reduced exposure to radiation through automated image acquisition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual positioning of the imager is used based on two-dimensional images, then the technician can adjust the position, but the positioning time increases and radiation exposure to the patient increases
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated navigation system that uses three-dimensional imaging data and computer algorithms to calculate and guide the imager to the target position automatically, eliminating the need for manual trial-and-adjustment positioning
Solution Approach 2:
The patent creates a three-dimensional digital copy of the patient's anatomy through CT or MRI scanning, which serves as a virtual model for planning and guiding the imager position, replacing the need for manual positioning based on two-dimensional images
2Measurement precision
If manual positioning with trial and adjustment is used, then the technician can achieve desired image, but the amount of radiation exposure to the patient increases
Solution Approach 1:
The patent performs preliminary three-dimensional imaging and virtual planning before the actual imaging procedure, allowing the optimal imager position to be calculated in advance, thereby eliminating the need for multiple trial exposures during the procedure
Solution Approach 2:
The patent uses automated navigation based on three-dimensional data to precisely determine the imager position, replacing manual positioning that requires multiple trial adjustments and associated radiation exposure
3Productivity
If automated positioning system is implemented, then imaging time is reduced and radiation exposure is minimized, but system complexity increases
Solution Approach 1:
The patent integrates multiple functions into a single automated navigation system, including three-dimensional image acquisition, target position calculation, imager position guidance, and real-time tracking, thereby achieving high productivity without proportionally increasing overall system complexity
Solution Approach 2:
The patent introduces a computer-based navigation system as an intermediary between the imager and the patient, which automatically calculates and guides the optimal position, reducing the need for complex manual coordination and speeding up the process
