Multi-Resolution Flat Panel Detector for Variable X-Ray Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flat panel detectors have uniform resolution, which is inadequate for imaging applications requiring varying resolutions for different anatomical parts, as using multiple detectors is not feasible.
Innovation Solution
A multi-resolution flat panel detector is designed with a detector array, scan electronics, and readout electronics configured to achieve varying resolutions by incorporating high and coarse-resolution regions, or by simultaneously driving scan lines and combining data from data lines based on clinical needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a uniform resolution flat panel detector is used, then the detector structure is simple and easy to manufacture, but it cannot provide different resolutions for different anatomical regions
Solution Approach 1:
The detector array is divided into multiple regions with different resolutions (first region with first resolution, second region with second resolution). This segmentation allows different anatomical regions to be imaged at appropriate resolutions, providing adaptability without requiring multiple separate detectors.
Solution Approach 2:
Different regions of the detector are assigned different resolution characteristics. The first region provides high resolution for detailed anatomical structures while the second region provides lower resolution for broader anatomical areas, optimizing image quality based on local diagnostic needs.
2Adaptability or versatility
If multiple detectors with different resolutions are used, then different resolution requirements can be met, but the device complexity and cost increase
Solution Approach 1:
Multiple resolution capabilities are merged into a single detector by creating different resolution regions within one detector array. This combines the functionality of multiple detectors into one device, reducing system complexity while maintaining multi-resolution capability.
Solution Approach 2:
The single detector is designed to perform multiple resolution functions simultaneously. It can image different anatomical regions at different resolutions based on clinical requirements, making the detector universal for various imaging scenarios without needing multiple specialized detectors.
3Measurement precision
If high-resolution imaging is performed across the entire detector area, then detailed features can be captured, but the data processing load and imaging time increase
Solution Approach 1:
High resolution imaging is applied only where necessary (first region) rather than across the entire detector area. This partial application of high resolution reduces data processing load and imaging time while still capturing detailed features in critical anatomical regions.
