Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computer tomography (CT) systems lack the ability to efficiently combine different X-ray detector types for enhanced imaging capabilities and require manual intervention for detector positioning, limiting their functionality and compactness.
Innovation Solution
A CT system incorporating at least one X-ray beam source, a patient table, a first X-ray detector, a second X-ray detector integrated into the patient table, and an automatic drive mechanism for positioning the detectors, allowing for the use of multi-line and flat detector principles to improve imaging efficiency and reduce manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple X-ray detector types are combined for enhanced imaging capabilities, then imaging quality and versatility are improved, but device complexity increases
Solution Approach 1:
The patent combines a first X-ray detector and a second X-ray detector into a single integrated detector unit. The first detector (multi-row detector with scintillator) and second detector (flat-panel detector) are structurally merged, allowing both detector types to function simultaneously within one unified structure, thereby improving imaging versatility while managing system complexity.
Solution Approach 2:
The integrated detector unit serves multiple functions: it can perform conventional CT imaging using the first detector, projection imaging using the second detector, and switch between different imaging modes. This multi-functionality allows a single device to replace what would traditionally require separate imaging systems.
2Ease of operation
If manual intervention is required for detector positioning, then positioning flexibility is maintained, but operational efficiency and productivity decrease
Solution Approach 1:
The detector unit is designed with movable components that can dynamically adjust the position of the first and second detectors. The drive mechanism enables real-time repositioning during examinations, allowing the system to adapt to different imaging requirements without manual intervention, thereby improving both ease of operation and productivity.
Solution Approach 2:
The system incorporates an automatic drive mechanism that self-regulates detector positioning based on imaging requirements. The electronic control device automatically actuates the drive mechanism to position detectors in the beam path or outside the beam path as needed, eliminating the need for manual operation and improving imaging efficiency.
3Volume of moving object
If X-ray detectors are integrated into the patient table for compact design, then space utilization is improved, but device complexity increases
Solution Approach 1:
The patent integrates the first and second X-ray detectors directly into the patient table structure. The detector unit is merged with the table, eliminating the need for separate detector housings and support structures. This integration achieves compact design by utilizing the existing patient table volume while reducing the overall system footprint.
