Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of X-ray diagnosis apparatuses face challenges in intuitively understanding how to adjust the diaphragm blades and compensating filters using the console, which can hinder the adjustment process.
Innovation Solution
The X-ray diagnosis apparatus includes a console with physical operating units corresponding to the diaphragm blades and compensating filters, allowing operators to intuitively control the movement and positioning of these components by matching the direction of operation with the displayed X-ray image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the console uses conventional control mechanisms for adjusting diaphragm blades and compensating filters, then the device functionality is complete, but the ease of operation deteriorates because operators cannot intuitively understand how to adjust the components
Solution Approach 1:
The console creates a virtual copy of the X-ray irradiation field displayed on the display unit, allowing operators to see the exact arrangement of diaphragm blades and compensating filters in real-time. This visual copying enables intuitive understanding of component positions and adjustment directions without requiring complex mental mapping between physical controls and actual component arrangements.
Solution Approach 2:
The system provides real-time visual feedback by displaying the current arrangement of diaphragm blades and compensating filters on the display unit. When operators adjust the components, the display immediately reflects these changes, creating a closed-loop feedback system that enhances operational intuition and reduces adjustment time.
2Manufacturing precision
If the console provides detailed control over diaphragm blades and compensating filters, then the manufacturing precision is improved, but the ease of operation deteriorates due to increased complexity of adjustment procedures
Solution Approach 1:
The display unit creates a visual replica of the X-ray irradiation field, showing the precise positions of diaphragm blades and compensating filters. This visual copying allows operators to accurately understand component arrangements and make precise adjustments while maintaining operational simplicity through intuitive visual guidance.
Solution Approach 2:
The system replaces complex mechanical adjustment procedures with a visual display system that shows component positions and arrangements. This substitution allows operators to understand and control the precise positioning of diaphragm blades and compensating filters through visual feedback rather than relying solely on tactile mechanical control.

AI summary
An X-ray diagnosis apparatus according to an embodiment includes an X-ray limiter having four diaphragm blades; and a console on which four physical operating units that correspond to the four diaphragm blades are placed at four positions. When viewed from the side of the operator of the console, the four operating units are placed on the far side, the near side, the left side, and the right side. The far-side operating unit, the near-side operating unit, the left-side operating unit, and the right-side operating unit correspond to the upper diaphragm blade, the lower diaphragm blade, the left-side diaphragm blade, and the right-side diaphragm blade, respectively, with reference to an X-ray image displayed in a display. An operation of moving the far-side operating unit in the far-side direction results in the movement of the upper diaphragm blade in the upward direction of the X-ray image displayed in the display, and an operation of moving the far-side operating unit in the near-side direction results in the movement of the upper diaphragm blade in the downward direction of the X-ray image displayed in the display. An operation of moving the near-side operating unit in the far-side direction results in the movement of the lower diaphragm blade in the upward direction of the X-ray image displayed in the display, and an operation of moving the near-side operating unit in the near-side direction results in the movement of the lower diaphragm blade in the downward direction of the X-ray image displayed in the display. An operation of moving the left-side operating unit in the leftward direction results in the movement of the left-side diaphragm blade in the leftward direction of the X-ray image displayed in the display, and an operation of moving the left-side operating unit in the rightward direction results in the movement of the left-side diaphragm blade in the rightward direction of the X-ray image displayed in the display. An operation of moving the right-side operating unit in the leftward direction results in the movement of the right-side diaphragm blade in the leftward direction of the X-ray image displayed in the display, and an operation of moving the right-side operating unit in the rightward direction results in the movement of the right-side diaphragm blade in the rightward direction of the X-ray image displayed in the display.
