Current radiography systems face challenges in generating clear images of the human spine due to the curvature and angular arrangement of vertebrae, which can obscure details between adjacent vertebrae and discs, hindering effective diagnosis and treatment of spinal anomalies.
Innovation Solution
A radiography system and method that involve a generator and detector with customizable movement sequences based on patient-specific anatomy, allowing for precise positioning and directional alignment of electromagnetic radiation to capture detailed images of the spine, including the use of generator and detector sequences that determine optimal positions and angles to orthogonalize the radiation projection relative to vertebral paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional radiography systems use fixed generator and detector positions, then the device complexity is reduced, but the image quality and diagnostic capability deteriorate due to inability to orthogonalize radiation projection relative to curved vertebral paths
Solution Approach 1:
The patent implements dynamic positioning of the generator and detector through computer-controlled movement along predefined sequences. The generator can rotate and translate to different angular positions, and the detector can move correspondingly to maintain optimal imaging geometry. This dynamic capability allows the system to adapt to the curved anatomy of the spine, orthogonalizing the radiation projection relative to vertebral paths, thereby improving image quality without requiring multiple fixed imaging stations
Solution Approach 2:
The radiography system integrates multiple functions into a single device: the generator can generate electromagnetic radiation at multiple angles and positions, the detector can detect radiation from various orientations, and the computer coordinates these movements according to patient-specific anatomy. This multi-functional design allows one device to perform what would traditionally require multiple fixed imaging stations, improving image quality while controlling overall device complexity
2Adaptability or versatility
If radiography systems use standardized imaging sequences, then the ease of operation is improved, but the adaptability to patient-specific spinal anatomy deteriorates, resulting in obscured vertebral details
Solution Approach 1:
The system performs preliminary actions by pre-calculating patient-specific imaging sequences based on imported spinal anatomy data before actual image acquisition. The computer determines the optimal generator and detector positions and angles in advance, creating a customized imaging protocol that adapts to the patient's unique vertebral curvature and orientation. This preliminary planning enables the system to automatically execute the customized sequence, maintaining ease of operation while achieving high adaptability to patient-specific anatomy
Solution Approach 2:
The system incorporates feedback mechanisms where the computer receives data about the patient's spinal anatomy (from prior imaging or registration), processes this information to determine optimal imaging parameters, and then executes the customized sequence. The system can also receive feedback during the imaging process to adjust positioning, ensuring adaptability to the actual patient anatomy while maintaining operational simplicity through automated control
