X-ray Diagnostic Apparatus User Face Tracking Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical imaging, particularly during surgical operations, it is cumbersome for users to adjust the imaging angle for stereoscopic viewing of X-ray images, which requires acquiring multiple images from various directions, increasing the exposure dose to the object and complicating the interpretation of stereoscopic vision videos.
Innovation Solution
An X-ray diagnostic apparatus with a supporting mechanism that automatically adjusts the imaging position based on user movement displacement, allowing for intuitive re-setting of the imaging angle and reducing the need for multiple image acquisitions by using position specifying circuitry to determine user movement and re-configure the imaging angle accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple images are acquired in advance to enable stereoscopic vision from multiple directions, then the user can view the object from different directions, but the exposure dose of the object increases
Solution Approach 1:
The system pre-acquires a plurality of X-ray images from different imaging positions and stores them in memory. When the user wants to view from a different direction, the system retrieves and processes the appropriate pre-acquired images to generate stereoscopic video, avoiding the need for additional exposure.
Solution Approach 2:
The system creates stereoscopic video copies from pre-acquired two-dimensional X-ray images through image processing. Instead of acquiring new images for each viewing direction, the system generates multiple stereoscopic video representations from the same set of source images, eliminating redundant exposure.
2Adaptability or versatility
If the user manually re-sets the imaging angle for stereoscopic viewing, then the desired viewing direction can be achieved, but the operation becomes cumbersome during surgical procedures
Solution Approach 1:
The system automatically determines the user's desired viewing direction by detecting the position of the user's face using a camera and face recognition algorithm. The imaging angle is automatically adjusted according to the detected face position, eliminating the need for manual setting operations.
Solution Approach 2:
The system continuously monitors the user's face position and dynamically adjusts the imaging angle in real-time based on this feedback. This closed-loop control allows the system to adapt to user movements and maintain optimal viewing angles without requiring manual intervention.
3Adaptability or versatility
If the supporting mechanism is moved to different imaging positions, then stereoscopic vision from multiple directions is enabled, but the time and complexity of operation increase
Solution Approach 1:
The supporting mechanism is pre-positioned to acquire images from multiple standard imaging positions (e.g., left anterior oblique, right anterior oblique) before the procedure begins. These pre-acquired images can be dynamically combined to create stereoscopic views from various directions without requiring physical movement during the procedure.
