| 中文摘要: |
| 放射诊断检查中存在电离辐射风险,遵循最优化和辐射防护领域"尽可能低的合理水平"(ALARA)原则实施的屏蔽防护,是减少受检者辐射剂量的措施之一。由于放射诊断检查模式和项目繁多、X射线线束特点和照射方式不同、成像设备图像质量和辐射剂量相关参数自动选择的方式各异和人体组织器官的辐射敏感性不同等,对临床实践中屏蔽防护的实施提出了较高的要求。本文就各类放射诊断检查中屏蔽用品、屏蔽方式、屏蔽效果以及在当前应用中的现状和存在问题进行了综述,以期为后续的相关研究和临床实践提供参考。 |
| 英文摘要: |
| There exist risks of ionizing radiation in radiodiagnosis examinations. Implementing shielding protection following the optimization and as low as reasonably achievable (ALARA) principles represents a measure to reduce radiation doses to patients. The implementation of shielding protection in clinical practices should meet high requirements due to variations in the modalities and items in radiodiagnosis examinations, the characteristics and irradiation method of X-ray beams, the method of automatic selection of image quality and radiation dose-related parameters by imaging equipment, the radiation sensitivity of human tissues and organs. This review introduced the shielding products, methods and effects in various radiodiagnosis examinations, as well as the current status and challenges in their applications, aiming to provide a reference for future related research and clinical practices. |
