HN7T3R8H3T7 ZZ3B6R1B8D5E、X线摄影时用增感屏，可增加辐射剂量正确答案：D 答案解析：由于透视对比度和清晰度较差，难于观察密度与厚度差别小的器官以及密度与厚度较大的部位，可对器官动态观察，用增感屏是为了提高射线的利用率，减少辐射剂量。14、腹部 X线摄影能显示肾轮廓原因，与哪一组织有关A、尿B、空气C、血液D、肌肉E、脂肪正确答案：E 15、骨、肌肉、脂肪、液体、空气在X线片的白黑排序A、骨、肌肉、脂肪、液体、空气B、骨、肌肉、液体、脂肪、空气C、骨、液体、肌肉、脂肪、空气D、骨、液体、肌肉、空气、脂肪E、骨、肌肉、液体、空气、脂肪正确答案：B 答案解析：基础常识。不同密度组织与X线成像的关系，当强度均匀的X 线穿透厚度相等、密度不同的组织结构时，由于吸收程度不同，在X线胶片上(或荧屏上)显出具有不同层次灰度(黑白)差异的 X线影像。骨密度最高，对X 线吸收多，照片上呈高亮度，肌肉、液体、脂肪依序次之，气体密度最低，X 线吸收少，照片上呈低亮度。16、关于 CR及 DR，正确的是A、CR摄像的时间分辨力显著提高B、CR摄影提高密度分辨力，但辐射剂量增加C、CR的空间分辨力高，对病变骨骼的细微结构的观察明显提高D、DR的缺点在于难以与原有X线设备匹配，对于一些特殊体位的投照，不如CR灵活E、DR空间分辨力进一步提高，信噪比高，成像速度快，但探测器寿命缩短文档编码:CT5S8N2J2A6 HN7T3R8H3T7

答案解析：CR可以与任何一种传统X线设备匹配，DR则难以与原X线设备匹配。18、关于 X线产生的叙述，不正确的是A、必须有高速电子流由阴极向阳极行进B、必须向X线管两极提供高电压C、乳腺 X线管的靶面由钨制成D、由靶面接受高速电子的能量E、X线管产生的X线仅占总能量的1%左右正确答案：C 答案解析：要想产生X线，必须有高千伏产生的电场和真空条件下产生的高速电子流撞击靶面；乳腺摄影用X线管的靶面物质是钼。19、关于 X线的叙述，不正确的是A、X 线比可见光的波长短B、X线本质是一种电磁波C、X线具有一定的波长和频率D、X线属于电磁波中的电离辐射E、X线是带电粒子正确答案：E 答案解析：X 线本质是一种电磁波，具有一定的波长和频率，由于X线光子能量大，可使物质产生电离，所以属于电磁波中的电离辐射，X线肉眼看不见，不带电。20、关于 X线防护原则，不正确的是文档编码:CT5S8N2J2A6 HN7T3R8H3T7 ZZ3B6R1B8D5文档编码:CT5S8N2J2A6 HN7T3R8H3T7 ZZ3B6R1B8D5文档编码:CT5S8N2J2A6 HN7T3R8H3T7

ZZ3B6R1B8D5A、建立剂量限制体制B、缩短受照时间C、最简易的防护措施是距离防护D、缩短焦物距E、减少 X线发射剂量正确答案：D 答案解析：X线的防护原则是建立质量限制体系，建立防止外照射的基本方法：缩短受照时间，增大与射线源的距离，建立屏蔽防护，固有防护为主、个人防护为辅，X线工作者与被检者防护兼顾，合理降低个人受照剂量与全民检查频率。对照此基本方法，D 项叙述是错误的。21、关于 X线检查的防护，说法不正确的是A、X 线穿透人体将产生一定的生物效应B、接触的X线量超过容许的辐射量，就将发生放射损害C、合理使用X线，避免不必要的检查，特别是重视孕妇及小儿患者的检查D、主动防护的目的是尽量减少X线的发射剂量，选择适当的摄像参数E、被动防护的目的是使受检者尽可能地少接受射线剂量正确答案：B 答案解析：接触的X 线量超过容许的辐射量，有可能发生放射损害。22、关于 X线检查方法的选择，下述哪项是不正确的A、高电压摄影用于显示那些在常规摄影中被高密度组织或病变遮挡的正常组织或病理改变B、体层摄影多用于了解病变内部的情况C、放大摄影用以显示较细微的病变D、造影检查用于显示缺乏自然对比的组织结构E、以上都不是正确答案：E 答案解析：高电压摄影由于穿透力强，用于显示那些在常规摄影中被高密度组织或病变遮挡的正常组织或病理改变；体层摄影可获得某一选定层面上的影像，用以明确平片难于显示、重叠较多和处于较深部位的病变，多用于了解病变内部的情况。23、关于 X线物理效应的叙述，正确的是文档编码:CT5S8N2J2A6 HN7T3R8H3T7 ZZ3B6R1B8D5文档编码:CT5S8N2J2A6 HN7T3R8H3T7
