Exposure and image quality in xeroradiography were studied in a test object and in patient tomographic examinations of the chest. With increased tube voltage and added copper filtration, skin exposure was reduced up to a factor of 10 without loss of image quality.
在一个测试物体以及胸部患者断层扫描检查中，对干板X线摄影中的曝光和图像质量进行了研究。随着管电压增加以及添加铜滤过，皮肤曝光可降低至十分之一，且图像质量无损失。
