Phantom-image, line-pair resolution and anterior eye exposure have been measured to determine the optimum collimation and eye shielding for petrous temporal tomography. Small round collimation and 0.5-1.0-mm lead equivalent eye shields are recommended. This reduces eye exposure to 10% of the usual dose without changing line-pair resolution.
已对模拟图像、线对分辨率和眼前部暴露情况进行了测量，以确定岩骨颞骨断层扫描的最佳准直和眼部防护措施。建议采用小圆形准直和等效铅厚度为0.5 - 1.0毫米的眼部防护板。这可将眼部暴露剂量降低至通常剂量的10%，同时不改变线对分辨率。
