Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray detectors require separate devices to measure X-ray radiation angles, which is impractical in non-specialized environments and can lead to image distortion due to tilted X-ray incidence.
Innovation Solution
An X-ray detector design that incorporates a top receiving container with subjects made of lead or tungsten, an X-ray detection unit with a scintillator and sensor panel, and a memory to calculate X-ray radiation angles using shadow images and trigonometric functions, allowing for autonomous measurement of X-ray radiation angles and image correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate devices are used to measure X-ray radiation angles, then measurement capability is provided, but device complexity and impracticality in non-specialized environments increase
Solution Approach 1:
The patent combines the X-ray detection function with the angle measurement function into a single integrated detector. The detector includes a scintillator, sensor panel, and processing unit that together perform both imaging and angle measurement, eliminating the need for separate measurement devices and reducing overall system complexity.
Solution Approach 2:
The X-ray detector is designed to perform multiple functions: it detects X-ray images and simultaneously measures X-ray radiation angles. The processing unit analyzes shadow images formed by X-rays passing through the detector to calculate radiation angles, making the detector a universal device for both imaging and measurement purposes.
2Productivity
If tilted X-ray incidence occurs, then imaging capability is maintained, but image distortion increases
Solution Approach 1:
The processing unit receives shadow images from the sensor panel and calculates the actual radiation angle based on the position and shape of shadows formed by the detector's internal structure. This feedback mechanism allows the system to detect tilt conditions and compensate for image distortion by correcting the positional information based on the measured angle.
Solution Approach 2:
The system changes the parameter representation from raw sensor coordinates to corrected positional information by incorporating radiation angle data. The processing unit transforms the image data based on the calculated angle, adjusting the spatial parameters to compensate for distortion caused by tilted X-ray incidence.
3Measurement precision
If external measuring devices are used, then angle measurement is achieved, but ease of operation and portability decrease
Solution Approach 1:
The X-ray detector performs self-measurement of radiation angles using its own internal structure as the measuring element. The detector's housing components serve as the measurement reference, eliminating the need for external measuring devices and simplifying operation to a single X-ray exposure without requiring additional equipment setup.
