本研究在单个尸体模型中使用不同的辐射剂量设置评价了三种术中成像系统（Airo、Spin、O-arm）的辐射暴露和图像质量。使用每个系统的三种制造商剂量方案获得L4-5内固定器械的轴向图像。测量包括散射辐射剂量、主观和客观图像质量（IQ）以及患者有效剂量（艾德）估计值。在每个剂量水平下，每个系统选择4个图像。使用Likert量表（1-最佳，5-最差），9名评审员对相同的36张图像进行了评分。客观IQ测量每张图像中条纹伪影（金属物体的错误数据线）的程度。基于艾德和主观和客观评分得出复合品质因数（FOM）。最佳的主观IQ评分为Spin中等剂量（1.44）、高剂量（1.78）和Airo低剂量（2.22）。最好的客观智商得分是Airo（87.3），其次是Spin（89.1）。艾德低剂量结果（mSv）包括Airo（1.6）、Spin（1.9）和O型臂（3.3）。艾德高剂量结果（mSv）包括Spin（4.6）、Airo（9.7）和O型臂（9.9）。低剂量（μ戈伊）的散射辐射测量包括Spin（21.9）、Airo（31.8）和O型臂（33.9）。高剂量散射辐射（μ戈伊）包括Spin（55.9）、O-arm（104.5）和Airo（200）。最佳FOM评分是Airo低剂量，其次是Spin中等剂量和高剂量。术中成像系统的选择需要更好地了解辐射暴露和IQ的风险和受益。
This study evaluated the radiation exposure and image quality for three intraoperative imaging systems (Airo, Spin, O-arm) using varying radiation dose settings in a single cadaver model. Axial images of L4–5 instrumentation were obtained using three manufacturer dose protocols for each system. Measurements included scattered radiation dose, subjective and objective image quality (IQ) and estimates of patient effective dose (ED). Four images per system were selected at each dose level. Using the Likert scale (1- best, 5- worst), nine reviewers rated the same 36 images. Objective IQ measures the degree of streak artifacts (lines with incorrect data from metal objects) in each image. A composite figure of merit (FOM) was derived based on ED and subjective and objective scores. The best subjective IQ scores were Spin medium (1.44), high dose (1.78), and Airo (2.22) low dose. The best objective IQ scores were Airo (87.3), followed by Spin (89.1). ED low dose results in mSv included Airo (1.6), Spin (1.9) and O-arm (3.3). The ED high-dose results in mSv included Spin (4.6), Airo (9.7) and O-arm (9.9). Scatter radiation measurements for low dose in μGy included Spin (21.9), Airo (31.8) and O-arm (33.9). Scatter radiation for high dose in μGy included Spin (55.9), O-arm (104.5) and Airo (200). The best FOM score was for the Airo low dose, followed by Spin medium and high dose. The selection of intraoperative imaging systems requires a greater understanding of the risks and benefits of radiation exposure and IQ.
