Mobile Lower Shield for Radiographic Table Radiation Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical personnel performing radiographic procedures face radiation exposure from various sources, including secondary radiation transmitted through patients, despite wearing protective clothing and using radiation shields, due to inadequate protection below the radiographic table.
Innovation Solution
A mobile lower shield system with a primary screen made of lead-impregnated acrylic, connected to a lower shield frame with wheels and hand rails, which includes a toe drape and secondary screen to block radiation from beneath and above the table, ensuring comprehensive radiation protection for medical personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If heavy lead protective clothing is worn to reduce radiation exposure, then radiation protection is improved, but long-term adverse effects such as disabling spinal disorders occur
Solution Approach 1:
The patent introduces a mobile radiation shield as an intermediary barrier between the radiation source and medical personnel. The shield includes a lead-acrylic screen mounted on a mobile frame with wheels, allowing it to be positioned between the x-ray tube and the personnel. This intermediary structure provides radiation protection without requiring personnel to wear heavy lead clothing, thereby eliminating the harmful effect of spinal disorders while maintaining protection against radiation exposure.
2Object-affected harmful factors
If radiation shields are used to block radiation, then radiation protection is improved, but gaps beneath the table allow radiation to reach personnel
Solution Approach 1:
The patent extends the radiation shield into the vertical dimension by including a toe drape that extends downward from the main screen to near the floor, and by positioning the mobile shield to block the space beneath the radiographic table. This three-dimensional extension ensures that radiation cannot bypass the shield through gaps beneath the table, making the protection comprehensive and reliable by addressing the previously unprotected lower dimension.
3Adaptability or versatility
If the radiation source is adjusted to extend beneath the table for cranial views, then imaging capability is improved, but radiation radiates below the table increasing exposure risk
Solution Approach 1:
The patent employs a mobile radiation shield with wheels that can be dynamically repositioned according to the radiation source position. When the x-ray tube is adjusted to extend beneath the table for cranial views, the mobile shield can be moved to block the radiation path in that specific configuration. This dynamic adaptability allows the shield to effectively counteract radiation exposure risks while maintaining the imaging system's versatility and ability to perform various imaging views.
