For a better result, you can use the middle streak. Unhide this layer, recolor it to the dark yellow (#AA6F00), and add a layer mask. Into this mask, draw in the middle with a big soft black brush, and the layer will be visible only on the sides, not in the middle.

为了一个更好的效果，你可以用一个中间蒙版，取消隐藏这个图层，用暗黄色(#AA6F00)重新着色，并添加一个图层蒙版，在这个蒙版中，在中间用大的软的黑色笔刷绘制，这样图层将只有边缘可见，中间不可见。

Results: In 2007, we provided 602 SPET/CT services in myocardial perfusion scan for attenuation correction and 202 SPET/CT services in other scans for image fusion. Among 64 regional bone SPET/CT services, we noted 2 (3.13%) significant motion artifacts and 2 (3.13%) streak artifacts induced by beam hardening effect while among 25 Ga-67 local SPET/CT services. According to the features including low tube currents and slow rotating speed of this SPET/CT, some problems such as the patient safety, longer scan time, alignment mismatch and radiation protection would be analyzed and discussed.

结果：2007年804例SPET/CT造影中，602例心肌血流灌注断层摄影进行衰减校正，共202例病例进行影像融合，其中鎝－99m-MDP局部SPET/CT发生「影像上明显可见的移动假影」的比例为3.13%(2/64)，镓－67局部SPET/CT发生移动假影的比钊则为24%(6/25)，因射束硬化效应所造成的条状假影有产生干扰融合影像判读的情形，其他问题包括SPET/CT之CT低管球电压及低转速之机器特性、受检者的安全、较长的造影时间、对位错误及辐射防护筝。
