Radiography Camera Motion Weighting for Anesthesia Wear-Off Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In interventional radiology procedures, doctors need to interrupt their operations to visually check the patient's condition for anesthesia wear-off, which is difficult due to the separation of endoscope and fluoroscopic images, and existing systems fail to accurately determine this without disrupting the procedure.
Innovation Solution
A radiography apparatus with a camera and movement amount calculation unit that processes images to detect and weight movement of multiple subject parts, notifying operators of anesthesia wear-off through alarms or displays when movement thresholds are exceeded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple images are displayed on the operation screen to monitor patient condition, then the doctor can recognize anesthesia wear-off, but the display regions for endoscope and fluoroscopic images are reduced
Solution Approach 1:
The patent transitions from displaying multiple separate images (2D plane occupation) to overlaying camera images with fluoroscopic images (composite layering). The camera image is superimposed on the fluoroscopic image, allowing simultaneous visualization of patient condition and procedural information without consuming additional display space.
Solution Approach 2:
The patent merges the camera image and fluoroscopic image into a single composite display. The movement amount calculation unit processes camera images to detect patient movement, and this information is integrated with the fluoroscopic image display, combining multiple information sources into one unified visual interface.
2Measurement precision
If the doctor visually checks the patient condition, then anesthesia wear-off can be detected, but the operation of endoscope or catheter must be temporarily stopped
Solution Approach 1:
The system provides continuous automated feedback about patient movement to the doctor through the display interface. The movement amount calculation unit continuously monitors camera images and provides real-time movement information, eliminating the need for the doctor to stop and visually check the patient, thus maintaining procedural efficiency while ensuring accurate anesthesia monitoring.
Solution Approach 2:
The system performs self-monitoring of patient condition through automated movement detection. The camera and movement amount calculation unit automatically track patient state without requiring doctor intervention, allowing the doctor to continue the procedure uninterrupted while the system independently monitors for anesthesia wear-off signs.
3Area of stationary object
If a single part of the patient is displayed, then the display region is maintained, but it is difficult to determine anesthesia wear-off comprehensively
Solution Approach 1:
The patent overlays the camera image (containing information about multiple patient parts) onto the fluoroscopic image, utilizing the vertical layering dimension rather than horizontal space. This allows comprehensive monitoring of multiple body parts simultaneously within the same display region.
Solution Approach 2:
The camera image serves multiple functions simultaneously: it provides visual information about multiple patient parts for comprehensive anesthesia monitoring, while also being integrated with the fluoroscopic image to maintain procedural context. The single display region thus delivers multi-functional information.

AI summary
A radiography apparatus is provided in which a doctor can recognize wear-off of anesthesia without interrupting an operation of an endoscope or the like. With the radiography apparatus, images of a plurality of parts of a subject are extracted from an image captured by a camera to calculate a movement amount for each part. The calculated movement amount for each part is weighted with a weight that is determined in advance for each of the plurality of parts, and in a case in which the movement amount after the weighting exceeds a predetermined threshold value, an operator is notified that the movement amount after the weighting exceeds the predetermined threshold value.
