目标概要：操作移动的影像增强器系统（C形臂）的手术室人员（ORP）需要接受培训，以便在最短的时间和最少的X射线暴露下拍摄高质量的X光片。我们的研究旨在评估CBT系统virtX的接受度、可用性和学习效果，该系统在手术病例场景中模拟基于C形臂的X射线成像。研究方法：在ORP过程中进行的前瞻性干预性研究分为三组：干预组1（使用virtX在PC上进行培训）和2（使用C形臂作为输入设备的virtX），以及对照组（不使用virtX进行培训）-IV 1、IV 2和CG。所有参与者都完成了同样的训练。记录产生足够质量的图像所需的时间，并使用单因素方差分析和Dunnett事后检验（？）= .05）。virtX的可接受性和可用性已经使用问卷进行了评估。结果：CG组（n = 21）比IV 2组（n = 20）需要更多的运动时间：133 ± 55比101 ± 37秒。（p = .03）。IV 1（n = 12）也优于CG（128 ± 48秒），但无统计学意义。79名参与者返回了调查问卷（81%为女性，年龄34 ± 9岁，专业经验8.3 ± 7.6年; 77%经常使用C形臂）。83%的人认为virtX是传统C形臂训练的有用补充。91%的人认为虚拟X线摄影有助于理解C形臂操作。结论：受训者体验virtX作为C形臂训练的实质性增强。使用virtX进行培训可以减少执行映像任务所需的时间。
Summary Objectives: Operating room personnel (ORP) operating mobile image intensifier systems (C-arms) need training to produce high quality radiographs with a minimum of time and X-ray exposure. Our study aims at evaluating acceptance, usability and learning effect of the CBT system virtX that simulates C-arm based X-ray imaging in the context of surgical case scenarios. Methods: Prospective, interventional study conducted during an ORP course with three groups: intervention group 1 (training on a PC using virtX), and 2 (virtX with a C-arm as input device), and a control group (training without virtX) – IV1, IV2 and CG. All participants finished training with the same exercise. Time needed to produce an image of sufficient quality was recorded and analyzed using One-Way-ANOVA and Dunnett post hoc test (? = .05). Acceptance and usability of virtX have been evaluated using a questionnaire. Results: CG members (n = 21) needed more time for the exercise than those of IV2 (n = 20): 133 ± 55 vs. 101 ± 37 sec. (p = .03). IV1 (n = 12) also performed better than CG (128 ± 48 sec.), but this was not statistically significant. Seventy-nine participants returned a questionnaire (81% female, age 34 ± 9 years, professional experience 8.3 ± 7.6 years; 77% regularly used a C-arm). 83% considered virtX a useful addition to conventional C-arm training. 91% assessed virtual radiography as helpful for understanding C-arm operation. Conclusions: Trainees experienced virtX as substantial enhancement of C-arm training. Training with virtX can reduce the time needed to perform an imaging task.
