Abstract:
Fluoroscopy is an advanced medical imaging modality that utilizes x-rays to acquire real-time images throughout a medical examination. It is commonly used in various procedures such as in interventional radiology, cardiac catheterization, and gastrointestinal and genitourinary studies. While fluoroscopy is a valuable diagnostic and therapeutic tool, it exposes patients and medical staff to ionizing radiation, which carries health risks. A radiation dose summary page is a report generated by the fluoroscope that displays important information about the procedure. It provides an overview of the radiation doses administered during a fluoroscopic procedure, as well as certain technical parameters used during the irradiation events. The contents of a radiation dose summary page may vary depending on the make and model of the fluoroscope but some common elements include the cumulative reference air kerma, which serves as a surrogate of radiation dose delivered to the patient, and the dose-area product, which takes account of the x-ray beam area and is a measure of the total amount of energy imparted on the patient. Other imaging acquisition parameters may be also included in the dose summary page, including tube voltage, tube current, pulse width, pulse rate, spectral filters, primary and secondary angles, and source-to-image distance. The radiation dose summary page for fluoroscopy is a useful tool for physicians, technologists, and medical physicists, allowing them to comprehend the technical details of a fluoroscopically guided procedure. ©RSNA, 2024.
摘要:
荧光镜检查是一种先进的医学成像模式,它利用X射线在整个医学检查中获取实时图像。它通常用于各种程序,例如介入放射学,心导管插入术,胃肠道和泌尿生殖系统研究。虽然透视是一种有价值的诊断和治疗工具,它使病人和医务人员暴露在电离辐射中,这会带来健康风险。辐射剂量汇总页面是荧光镜生成的报告,显示有关程序的重要信息。它提供了在荧光检查过程中施用的辐射剂量的概述,以及辐照事件期间使用的某些技术参数。辐射剂量汇总页面的内容可能会根据荧光镜的品牌和型号而有所不同,但一些常见元素包括累积参考空气角力,作为传递给患者的辐射剂量的替代品,和剂量面积产品,这考虑了X射线束面积,并且是对赋予患者的能量总量的测量。其他成像采集参数也可以包括在剂量总结页面中。包括管电压,管电流,脉冲宽度,脉搏率,光谱滤波器,主要和次要角度,和源到图像的距离。透视检查的辐射剂量摘要页面是医生的有用工具,技术人员,和医学物理学家,使他们能够理解透视引导程序的技术细节。©RSNA,2024.
