Methods: During the treatment simulation, get the patients simulator film and the computer location image at the same time.
方法:住院需放疗的肿瘤病人经模拟定位后, 即拍X线片,同时电脑采集定位图像。
Results: Compared with computer location image, the simulator film had a better image quality but lack of the image information.
结果:X线片的图像质量明显优于电脑采集图,而电脑采集图的资料内容明显多于X线片。
Time limits and computer location won't replace the need to educate kids about internet use and safety, but some people , just like me , doubt whether time limits or similar restrictions do much.
时间限制和电脑的位置将不会取代要教育孩子有关互联网的使用和安全,但有些人,就像我,怀疑是否有时间限制或类似的限制不大。
