To evaluate and compare the absorbed dose and image quality when applying a commercially produced fixation device (group A) and a vaccum mattress fixation device to pediatric patients (group B). We compared the absorbed dose and image noise between the groups at the phantom and clinical study. For phantom study, the measurement absorbed dose for a real time skin dosimeter was 3.0 mGy at the group A and 1.9 mGy at the group B (p < 0.05). For clinical study, computed tomography dose index product, dose-length and effective radiation dose were significantly lower with the group B compared to the group A, (3.4 mGy, 27.0 mGy-cm, and 2.2 mSv vs 4.4 mGy, and 36.7 mGy-cm, and 3.0 mSv), p < 0.05 for all comparisons. Compared to the commercially produced fixation device, the vaccum mattress fixation device composed of a less absorptive material enabled a reduction in the absorbed dose while maintaining the image quality during pediatric CT examinations.

使用真空床垫可以减少小儿 CT 期间的吸收剂量

评估和比较将商业生产的固定装置(A 组)和真空床垫固定装置应用于儿科患者(B 组)时的吸收剂量和图像质量。我们比较了模型和临床研究中各组之间的吸收剂量和图像噪声。对于体模研究,实时皮肤剂量计的测量吸收剂量在 A 组为 3.0 mGy,在 B 组为 1.9 mGy (p < 0.05)。对于临床研究,与 A 组相比,B 组的计算机断层扫描剂量指数乘积、剂量长度和有效辐射剂量显着降低(3.4 mGy、27.0 mGy-cm 和 2.2 mSv vs 4.4 mGy 和 36.7 mGy- cm, 和 3.0 mSv), p < 所有比较均为 0.05。与商业生产的固定装置相比,
