Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional MRI system is used, then high magnetic field strength is achieved, but physical access to the patient is limited and surgical interventions are restricted
Solution Approach 1:
The MRI system is divided into separate functional modules: a low-field MRI scanner for imaging and a high-field MRI scanner for calibration. This segmentation allows the surgical suite to have physical access while maintaining the necessary magnetic field strength for accurate imaging and calibration in separate locations.
Solution Approach 2:
A phantom object serves as an intermediary between the low-field MRI scanner and the high-field MRI scanner. The phantom contains calibration objects with known magnetic properties that can be scanned by either system, enabling the low-field system to be calibrated using the high-field system without requiring the surgical suite to have high magnetic field strength.
2Adaptability or versatility
If a fixed MRI phantom is used, then calibration is performed, but adaptability for different calibrations and validations is limited
Solution Approach 1:
The phantom is divided into multiple modular components that can be independently configured. Different calibration objects and inserts can be combined in various arrangements within the phantom housing, allowing the same basic phantom structure to adapt to different calibration requirements without increasing overall complexity.
Solution Approach 2:
The phantom is designed as a universal platform that can perform multiple functions: geometric distortion calibration, signal-to-noise ratio validation, contrast medium testing, and system performance verification. The modular design allows a single phantom to serve multiple calibration purposes by simply changing the internal configuration.
3Productivity
If multiple separate phantoms are used for different calibrations, then each calibration is optimized, but time and resources are consumed
Solution Approach 1:
The modular phantom serves as a universal calibration tool that can perform multiple calibration functions in a single system. By configuring different modular components within the same phantom, the system can complete multiple calibrations without requiring separate phantom objects, thereby reducing time and resource consumption.
Solution Approach 2:
The phantom components are pre-configured with known calibration objects and magnetic properties that can be quickly assembled and disassembled. This preliminary preparation allows for rapid switching between different calibration types without requiring time-consuming setup procedures, improving overall calibration efficiency.

AI summary
The present disclosure provides magnetic resonance phantom imaging phantoms and method of assembling thereof. In one aspect, a magnetic resonance imaging phantom can include a plurality of modular components. The plurality of modular components can include a first modular component, a second modular component, a shell, and a lid. The second modular component can be different than the first modular component. The shell can be structured to receive at least one modular component. The lid can be attachable to the shell to enclose the at least one modular component received within the shell.
