Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual positioning of imaging systems during 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.
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 the manual mechanical positioning system with an automated computer-controlled positioning system. The controller automatically moves the imager to the target position based on three-dimensional image data and calculated coordinates, eliminating the need for manual trial-and-adjustment positioning while reducing positioning time and radiation exposure.
Solution Approach 2:
The patent uses three-dimensional image data (CT or MRI scans) as a digital copy of the patient's anatomy to plan and guide imager positioning. This 3D model allows the system to calculate precise target positions and track the imager's location without requiring repeated 2D imaging during positioning, thereby reducing radiation exposure.
2Ease of operation
If manual positioning with trial and adjustment is performed, then the imager can be positioned, but the amount of radiation exposure to the patient increases
Solution Approach 1:
The system performs preliminary positioning planning using pre-acquired three-dimensional image data (CT or MRI scans) obtained before the procedure. The controller calculates the optimal target position and movement path in advance, allowing the imager to be positioned accurately on the first attempt without requiring trial adjustments that would increase radiation exposure.
Solution Approach 2:
The automated computer-controlled positioning system replaces manual positioning methods, using 3D image guidance and automated movement control to achieve accurate positioning without repeated 2D imaging attempts, thereby minimizing radiation exposure to the patient.
3Productivity
If automated positioning is implemented, then imaging time is reduced and radiation exposure is minimized, but the system complexity increases
Solution Approach 1:
The controller serves multiple functions: it acquires position information from tracking systems, processes three-dimensional image data, calculates target positions, controls imager movement, and tracks positioning in real-time. This multi-functionality consolidates what would otherwise require separate systems into a single integrated controller, managing complexity while enabling automated positioning.
Solution Approach 2:
The patent introduces a tracking system as an intermediary between the imager and the controller. This tracking system automatically provides position information to the controller, eliminating the need for complex sensors or markers on the imager itself while enabling precise automated positioning and real-time tracking.
4Measurement precision
If three-dimensional image data is used for positioning, then positioning accuracy is improved, but the initial setup time and complexity increase
Solution Approach 1:
The three-dimensional image data (CT or MRI scans) are acquired and processed in advance before the imaging procedure begins. The controller uses this pre-acquired data to calculate target positions and plan the imaging procedure, allowing for high positioning accuracy during the actual procedure without adding complexity or time during the procedure itself.
