Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional calibration phantoms with 2D inlay distributions are used, then equipment calibration is simplified, but the phantom cannot simulate real three-dimensional tissue morphology and pathology
Solution Approach 1:
The patent transitions from traditional two-dimensional inlay distributions to a three-dimensional arrangement of absorbing elements within the phantom matrix. This dimensional enhancement allows the phantom to simulate the spatial distribution and morphological characteristics of real tissue pathologies more accurately, preserving three-dimensional information while maintaining calibration functionality
Solution Approach 2:
The phantom employs a composite structure combining a transparent or semi-transparent matrix material with embedded absorbing elements of varying densities and compositions. This composite approach enables simultaneous achievement of structural integrity, realistic tissue simulation, and calibrated radiographic contrast properties
2Reliability
If phantoms are designed exclusively for equipment calibration, then calibration function is optimized, but the phantom cannot provide direct aid in disease diagnosis
Solution Approach 1:
The phantom is designed to fulfill multiple functions simultaneously: it serves as a calibration tool with known geometric and radiographic properties for equipment verification, while also containing simulated pathology features that can aid in diagnostic interpretation and training. This multi-functional design eliminates the need for separate calibration and diagnostic phantoms
3Measurement precision
If phantoms use materials not found in the human body (aluminum trioxide, calcium carbonate), then calibration standards are maintained, but the phantom does not portray real objects
Solution Approach 1:
The phantom employs different materials with specific properties in different regions: the matrix material provides overall structural support and baseline radiographic properties, while embedded absorbing elements with varying compositions and densities simulate specific tissue types and pathology characteristics. This localized material differentiation enables both calibration accuracy and realistic tissue portrayal
