Medical Imaging Bed Movement Direction Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical imaging systems with movement mechanisms, operators often face confusion regarding the movement direction corresponding to predetermined operation units on the console, leading to potential misalignment during bed movement operations.
Innovation Solution
A medical imaging system is designed with a console featuring operation units that, when touched or pressed, trigger a presenting unit to display information about the intended movement direction around the bed or on the table, ensuring clarity and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a marker beam is used to indicate movement direction, then visual guidance is provided, but the marker beam direction may not match the actual movement direction when the bed is moved with a predetermined operation unit
Solution Approach 1:
The system detects the actual movement direction of the bed through sensors and compares it with the indicated direction from the marker beam. When a mismatch is detected, the control unit adjusts the marker beam direction or provides corrective visual feedback to ensure accurate direction indication, creating a closed-loop feedback system that maintains reliability.
Solution Approach 2:
The control unit预先 (in advance) adjusts the marker beam direction based on predicted bed movement characteristics before the operator completes the movement action. By anticipating the movement direction and pre-aligning the marker beam, the system ensures directional accuracy is maintained throughout the movement process.
2Ease of operation
If the bed is moved using a predetermined operation unit on the console, then movement control is achieved, but the operator may not be able to determine the corresponding movement direction
Solution Approach 1:
The system introduces an intermediary visual indication device (marker beam or display) that mediates between the operation unit input and the actual bed movement. This intermediary provides real-time directional information that bridges the gap between the operator's action on the console and the resulting bed movement, ensuring the operator can determine the movement direction.
Solution Approach 2:
The system adds a visual dimension to the operational interface by projecting the marker beam in three-dimensional space or displaying directional arrows on a screen. This dimensional addition provides intuitive spatial orientation information that complements the two-dimensional console interface, enabling the operator to easily determine movement direction.
3Loss of information
If visual indication is provided around the bed or on the table, then movement direction information is communicated, but the indication may not be sufficiently clear or noticeable
Solution Approach 1:
The visual indication system uses distinct colors to represent different movement directions or states (e.g., green for forward movement, red for backward movement). These color changes provide intuitive and easily distinguishable visual cues that enhance the clarity and noticeability of the movement direction information without requiring excessive illumination intensity.
Solution Approach 2:
The marker beam is projected as a curved or arc-shaped visual indication rather than a straight line. This curved projection naturally guides the operator's eye along the intended movement path and enhances visibility by distributing the visual signal across a broader angular range, making the indication more noticeable from various viewing angles.

AI summary
To present, in advance, information about a movement direction corresponding to a predetermined operation unit of a console, a medical imaging system includes a bed 170 on which a subject is placed; a movement mechanism (bed movement mechanism 174) configured to move a table 158 on the bed 170 on the basis of operation information of a predetermined operation unit; a determining unit 118 configured to determine whether an operator has touched the predetermined operation unit; and a presenting unit (second presenting device 172) configured to present, around the bed 170 or on the table 158 on the bed 170, information about the movement direction corresponding to the predetermined operation unit when the determining unit 118 determines that the operator has touched the predetermined operation unit.
