Stationary Patient Table X-Ray Device with Movable Image Receptor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing X-ray scanning process is complex and time-consuming due to the need for precise positioning of the X-ray generator, patient table, and image receptor, requiring extensive movement and repositioning of these components during radiographic examinations.
Innovation Solution
The X-ray device employs a stationary patient table with a movable image receptor, allowing only the X-ray generator and image receptor to be positioned, eliminating the need for longitudinal and transverse movement of the tabletop, and incorporating motorized or manual drives for the image receptor to track the X-ray generator's movements, including rotational and tilting capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the patient table with floating tabletop is used to enable X-ray scanning, then the X-ray generator, patient table, and image receptor can be positioned relative to one another, but the procedure becomes complex and time-consuming due to the need for correct positioning of multiple components
Solution Approach 1:
Instead of moving the patient table with floating tabletop to position the patient, the invention inverts the approach by keeping the patient table stationary and moving only the image receptor and X-ray generator. This inversion simplifies the positioning procedure by eliminating the need to position three components (X-ray generator, patient table, image receptor) relative to each other, reducing the complexity while maintaining the same adaptability for X-ray scanning.
2Adaptability or versatility
If the floating tabletop is used to move the patient table longitudinally and transversely, then the patient can be scanned from head to foot without repositioning, but the drive and control means become complex and expensive
Solution Approach 1:
The invention inverts the conventional approach by eliminating the floating tabletop mechanism. Instead of moving the patient table longitudinally and transversely to enable scanning, the patient table remains stationary and the image receptor is moved to track the X-ray generator. This inversion dramatically simplifies the drive and control means, reducing manufacturing complexity and cost while preserving the scanning capability from head to foot without patient repositioning.
Solution Approach 2:
The invention extracts and eliminates the complex floating tabletop mechanism and its associated drive and control means. By removing this unnecessary component, the system achieves the same scanning functionality with significantly reduced complexity and lower manufacturing cost, while the image receptor tracking mechanism provides the required adaptability for head-to-foot scanning.
3Ease of manufacture
If the image receptor is moved manually without motor drive, then the device cost is reduced, but the positioning precision and tracking accuracy may be compromised
Solution Approach 1:
The invention implements self-service positioning where the image receptor automatically tracks the X-ray generator's movement. The system uses the X-ray generator's position and movement data to automatically adjust the image receptor position, eliminating the need for manual positioning while maintaining high precision. This self-service mechanism reduces device cost by eliminating motor drives while ensuring accurate positioning through automated tracking based on the X-ray generator's coordinates.

AI summary
An X-ray device for carrying out X-ray scans is configured for a simplified procedure. The X-ray device has an image receptor which operates in conjunction with an X-ray generator to carry out X-ray scans of a patient, and a patient table. A tabletop of the patient table which is used to position the patient during the X-ray scans, is immovable in the table plane. Instead, the image receptor is disposed in a longitudinally and transversely movable manner relative to the tabletop parallel to the table plane.
