Content used by Medical Physicists for fluoroscopy safety training to staff is deliverable via several formats, that is, online content or a live audience slide presentations. Here, we share one example of a kinesthetic (live, hands-on simulation) educational program in use at our facility for some time (~10 years). In this example, the format and content specifically target methods of reducing physician operator exposures from scattered x rays. A kinesthetic format identifies and promotes the adoption of exposure-reducing behaviors. Key kinesthetic elements of this type of training include: physician hands-on measurements of radiation levels at locations specific to their standing positions (e.g., primary arterial access points) in the room using handheld exposure rate meters, measurement of exposure rate reduction to physicians provided by using personal protective equipment, that is, wearable aprons, hanging lead drapes, and pull-down shields. Physician choice of procedure-specific tableside selectable controls affecting exposure rate from optional fluoroscopy, Cine or digital subtraction angiography (DSA), along with comparative measured contribution to physician exposure is demonstrated. The inverse square exposure rate reduction to physicians when stepping back from the table during DSA is a key observation. Kinesthetic simulations in the rooms used by physicians have been found to provide the highest level of understanding giving rise to adoption of practices that are impactful for physicians. Specific training scripts are in place for physician sub-specialization in interventional radiology, cardiology, neurosurgery, vascular surgery, and gastroenterology. This training is used for new physician staff while classroom presentations (whose content mimics in room training) are used with staff who have had previously had in room training.
医用物理学家为员工进行透视安全培训所使用的内容可以通过多种形式提供,例如在线内容或现场观众幻灯片演示。在这里,我们分享我们设施中使用的一种动觉(现场、动手模拟)教育计划的一个示例,该计划已经使用了一段时间(约 10 年)。在这个示例中,格式和内容专门针对减少医生操作人员从散射 X 射线中受到的照射的方法。动觉格式可识别并促进减少暴露的行为。这种培训的关键动觉元素包括:医生使用手持式辐射率计在房间内特定于其站立位置(例如主要动脉进入点)的位置进行辐射水平的实际测量,使用个人防护设备(即可穿戴围裙、悬挂铅帘和下拉屏蔽)为医生测量辐射率降低量。医生选择特定于手术的床边可选控件来影响可选透视、Cine 或数字减影血管造影(DSA)的辐射率,以及比较对医生暴露的影响,这一点得到了证明。在 DSA 期间从桌子后退时,医生的平方反比辐射率降低是一个关键观察结果。在医生使用的房间中进行动觉模拟已被发现可以提供最高水平的理解,从而促使医生采用有效的实践方法。已经为介入放射学、心脏病学、神经外科、血管外科和胃肠病学的医生亚专业制定了具体的培训脚本。这种培训用于新医生,而课堂演示(其内容模仿室内培训)则用于已经接受过室内培训的员工。
