Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional flat panel sensors are used for radiographic imaging, then the device can perform two-dimensional imaging, but image quality deteriorates due to parasitic radiation and radiation exposure to patient and operator increases
Solution Approach 1:
The detector is divided into multiple independent detector elements arranged in a matrix, with each element capable of independent operation. This segmentation allows selective activation of only those detector elements necessary for the specific imaging task, thereby reducing overall parasitic radiation exposure while maintaining image quality for the required field of view.
Solution Approach 2:
Different detector elements can be configured with different properties or activation states based on local requirements. The system activates only the specific detector elements needed for the current imaging procedure, creating a localized detection pattern that minimizes exposure to areas outside the region of interest while maintaining high-quality imaging where needed.
2Measurement precision
If multiple separate radiological imaging devices are acquired to perform different analyses, then high-quality imaging for each modality is achieved, but device complexity and operational costs increase substantially
Solution Approach 1:
The radiological imaging device is designed with a detector comprising multiple detector elements that can be selectively activated to perform different imaging modalities including radiography, fluoroscopy, and tomography. This multi-functional design allows a single device to replace multiple specialized devices, maintaining high imaging quality for each modality while reducing overall system complexity and operational costs.
Solution Approach 2:
The system employs dynamic configuration of the detector elements, where the activation pattern of detector elements changes based on the required imaging modality. This dynamic adaptability allows the same physical detector to optimally serve different imaging purposes by activating only the necessary elements for each specific procedure.
3Object-affected harmful factors
If anti-diffusion grids are added to reduce parasitic radiation, then radiation exposure is partially reduced, but image quality remains compromised and higher radiation doses are required
Solution Approach 1:
The system extracts and removes parasitic radiation signals from the detected data through selective reading of detector elements. By activating only the necessary detector elements for the specific imaging task and selectively reading out only those elements, the system effectively removes parasitic radiation contributions from areas outside the region of interest, improving image quality without requiring anti-diffusion grids or increasing radiation dose.

AI summary
A radiological imaging device that includes a source that emits radiation that passes through at least part of a patient, the radiation defining a central axis of propagation; and a receiving device that receives the radiation and is arranged on the opposite side of the patient with respect to the source. The receiving device includes a first detector to detect radiation when performing at least one of tomography and fluoroscopy, a second detector to detect radiation when performing at least one of radiography and tomography; and a movement apparatus arranged to displace the first and second detectors with respect to the source. The movement apparatus provides a first active configuration in which the radiation hits the first detector and a second active configuration in which the radiation hits the second detector.
