Enhanced Longitudinal-Positioning Indicator and Marking Grid for Radiographic Imaging
Legal Citation
Summary of the Inventive Concept
An improved system for radiographic imaging that integrates advanced longitudinal-positioning indicators and marking grids to enhance accuracy, efficiency, and patient safety.
Background and Problem Solved
The original patent's longitudinal-positioning indicator and marking grid, while providing orthogonal coordinates for medical procedures, have limitations in accommodating varying patient sizes and anatomical features. The new inventive concept addresses these limitations by introducing adjustable guidelines, real-time tracking, and integrated sensors to ensure precise and safe procedures.
Detailed Description of the Inventive Concept
The enhanced system comprises a longitudinal-positioning indicator with adjustable guidelines, allowing for real-time adaptation to patient size and anatomy. The marking grid is embedded with sensors to track patient movement and adjust coordinates accordingly. Additionally, the system includes a built-in scale for direct measurement of longitudinal-positioning coordinates, eliminating the need for patient table position calculation. The computer-aided system utilizes software modules to detect and correct for patient movement during CT scans, ensuring accurate and efficient procedures.
Novelty and Inventive Step
The new claims introduce novel features such as adjustable guidelines, real-time tracking, and integrated sensors, which provide a significant improvement over the original patent's design. The inventive step lies in the combination of these features to create a more accurate, efficient, and patient-centric system for radiographic imaging.
Alternative Embodiments and Variations
Alternative embodiments may include the use of different sensor technologies, adjustable grid sizes, or modular designs for increased versatility. Variations may also involve the integration of artificial intelligence or machine learning algorithms to further enhance the system's accuracy and efficiency.
Potential Commercial Applications and Market
The enhanced system has significant commercial potential in the medical imaging industry, particularly in CT-guided biopsy procedures. The system's improved accuracy, efficiency, and patient safety features make it an attractive solution for hospitals, clinics, and medical research institutions.
