Gantry Orientation Control for Multi-Room X-ray CT Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The availability factor of the gantry in angio-CT systems is low due to mismatched positional relationships and user interface displays when multiple examination rooms share a gantry, leading to operation errors.
Innovation Solution
An X-ray CT system with a gantry, couches, and control circuitry that adjusts movement control and user interface displays based on the combination of modalities, using sensors to detect the gantry's position and switch controls accordingly, ensuring correct operation direction and display alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a gantry is shared among multiple examination rooms, then the availability factor of the gantry is improved, but operation errors occur due to mismatched positional relationships and user interface displays
Solution Approach 1:
The patent implements dynamic switching of movement control and UI display based on the detected gantry position. The control circuitry automatically adapts the operation mode and interface display according to which examination room the gantry is currently serving, ensuring that the controls remain consistent with the gantry's actual positional relationship to the couch in each room.
Solution Approach 2:
The patent employs sensors to detect the gantry's position in each examination room and provides feedback to the control circuitry. This feedback mechanism enables the system to automatically identify the current room and switch the appropriate movement control and UI display configuration, preventing operation errors caused by mismatched interfaces.
2Device complexity
If movement control is fixed for a gantry, then the control is simple, but it causes mismatch when the gantry moves to different examination rooms with different couch positions
Solution Approach 1:
The movement control system is designed to dynamically switch between different control modes based on the gantry's detected position. When the gantry moves to a different examination room, the control circuitry automatically selects the appropriate movement control configuration that matches the positional relationship between the gantry and the couch in that specific room.
Solution Approach 2:
The patent changes operational parameters (movement control settings and UI display configurations) based on the gantry's position in different examination rooms. The control circuitry stores multiple sets of parameters corresponding to different rooms and automatically selects the appropriate set, allowing the system to adapt to varying couch positions and gantry orientations without requiring complex manual reconfiguration.
3Stability of the object's composition
If user interface display is fixed, then the display is consistent, but it shows incorrect movement directions when the gantry position changes relative to the couch
Solution Approach 1:
The user interface display is designed to dynamically switch between different display configurations based on the gantry's detected position. The control circuitry automatically adjusts the UI display to show correct movement directions and operational information that correspond to the current examination room and the gantry's positional relationship to the couch, maintaining both consistency within each room and adaptability across rooms.

AI summary
According to an embodiment, an X-ray CT system includes a gantry, a first couch, a second couch, a carrier unit, and control circuitry. The gantry includes an X-ray tube, an X-ray detector, and an operation unit. The first couch is arranged in a first room. The second couch is arranged in a second room. When carrying the gantry to the first room, the carrier unit arranges the gantry in an orientation in which the front side of the gantry faces the first couch. When carrying the gantry to the second room, the carrier unit arranges the gantry in an orientation in which the back side of the gantry faces the second couch. The control circuitry controls the direction of the tilt movement of the gantry in accordance with the room where the gantry is arranged.
