X-Ray Imaging Staff Dose Mapping for Surgery Room Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no mechanism to show the exposure dose corresponding to the position of each medical staff member in a surgery room during X-ray imaging, leading to varying radiation levels and potential health risks.
Innovation Solution
An X-ray imaging apparatus that includes an optical camera and dosimeter to sequentially acquire the position and exposure dose of staff members, associating and displaying this data to provide real-time radiation exposure awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fluoroscopy imaging and radiography imaging are performed in the surgery room, then diagnostic imaging capability is improved, but radiation exposure to medical staff increases
Solution Approach 1:
The system continuously monitors the positions of medical staff using optical cameras and dosimeters, and provides real-time feedback by displaying their locations and radiation exposure levels on a monitor. This feedback mechanism enables staff to adjust their positions to minimize radiation exposure while maintaining imaging capabilities.
Solution Approach 2:
The patent introduces an intermediary system consisting of optical cameras, position detection devices, and a control device that mediates between the X-ray imaging system and medical staff. This intermediary provides real-time position and radiation level information without interfering with the imaging process.
2Ease of operation
If medical staff members move freely in the surgery room, then operational flexibility is improved, but radiation exposure control deteriorates
Solution Approach 1:
The system maintains staff mobility by providing real-time feedback on their positions and radiation exposure levels through visual display. Staff can freely move while the system continuously tracks their locations and provides feedback, enabling them to make informed decisions about positioning to minimize exposure.
Solution Approach 2:
The patent replaces mechanical radiation shielding barriers with an optical detection and information display system. Instead of physically blocking radiation, the system uses optical cameras and dosimeters to provide information that enables staff to avoid high-radiation areas voluntarily.
3Object-affected harmful factors
If radiation shielding measures are implemented, then radiation exposure is reduced, but visibility and monitoring of staff positions deteriorates
Solution Approach 1:
The system uses optical cameras as intermediary devices to detect staff positions without requiring physical shielding. The cameras capture visual information that is then processed to provide real-time position data, maintaining both radiation protection and position monitoring capabilities simultaneously.
Solution Approach 2:
The patent substitutes mechanical shielding structures with optical detection systems. The optical cameras and image processing replace the need for physical barriers, eliminating the trade-off between shielding and visibility by using a different detection mechanism that does not obstruct the field of view.
