Transparent Subject Check Unit for X-ray Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radiography machines face challenges in accurately and safely checking and correcting patient posture, particularly for oral cavity radiographs, due to direct laser exposure and obstructed views, leading to increased anxiety and frequent re-radiographing.
Innovation Solution
A radiography machine equipped with an alignment unit and a transparent subject check unit, featuring a touch panel and guide lines displayed on a transparent surface, allowing real-time posture correction and preference setting without direct laser exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If laser beam is irradiated on the face of the patient to measure posture, then the operator can determine whether the posture is correct, but the laser beam may be directly irradiated on the eyeballs of the patient causing safety issues
Solution Approach 1:
A transparent display unit is introduced as an intermediary between the laser beam and the patient's face. The display unit shows virtual alignment marks that guide posture positioning without requiring direct laser irradiation on the patient's sensitive areas, thereby maintaining measurement accuracy while eliminating harmful laser exposure to eyeballs
Solution Approach 2:
Instead of directly projecting laser beams onto the patient's face for alignment, the system creates a visual copy of alignment marks on a transparent display unit. This copy provides the same guidance function for posture measurement without the harmful effects of direct laser exposure
2Device complexity
If the radiography machine blocks the view of the patient or operator, then the machine structure is complete, but the operator must correct posture while watching a face image through a camera increasing patient anxiety
Solution Approach 1:
A transparent display unit is positioned within the radiography machine structure to serve as an intermediary viewing interface. This allows both the patient and operator to directly see through the machine structure during positioning, eliminating the need to rely on camera images and thereby reducing patient anxiety while maintaining complete machine functionality
Solution Approach 2:
The transparent display unit utilizes optical properties to allow visibility through the machine structure. By making the display medium transparent rather than opaque, the system enables direct visual contact between the patient/operator and the external environment, reducing psychological anxiety caused by enclosure
3Adaptability or versatility
If the operator handles detail settings of the radiography machine while correcting posture, then the radiography parameters can be adjusted, but the moving line of the operator is increased more than necessary
Solution Approach 1:
The transparent display unit is merged with the control interface, allowing the operator to view alignment information and adjust radiography parameters through the same interface. This integration eliminates the need for separate control panels and reduces operator movement by combining multiple functions in one location
Solution Approach 2:
The transparent display unit serves multiple functions simultaneously: it displays alignment marks for posture correction, provides visibility through the machine structure, and acts as an interface for parameter adjustment. This multi-functionality reduces the need for separate components and minimizes operator movement
4Measurement precision
If the posture of the patient does not reach the reference point of laser beam, then the alignment can be achieved, but accurate radiograph cannot be obtained leading to frequent re-radiographing
Solution Approach 1:
The transparent display unit provides real-time visual feedback through virtual alignment marks that clearly indicate when the patient's posture reaches the correct reference position. This enhanced feedback mechanism reduces alignment errors and minimizes re-radiographing, thereby improving radiography efficiency while maintaining high alignment precision
