Throughout my career in无损检测咨询随着时间的推移，有一个问题被问得越来越频繁：“我们的手术能改成电脑放射吗？”这个问题有点像问钢琴是怎么工作的。基本功能很容易理解，但实际操作的动作要复杂得多。像钢琴一样，计算机射线照相术有许多运动部件，即使是熟练的使用者也看不见。键盘前的椅子上那些引起人们兴趣的部分。我不是音乐大师，甚至不是一个音乐新手，然而，我可以在计算机射线照相术的许多移动部分的光。
回答共同的问题；是的，如果你愿意打下基础，你的业务可能会从传统的电影Radiography到计算机射线照相术（CR），变化很小。这主要是由于胶片和CR之间的相似性。与其他数字模式不同，曝光介质（胶片替换）是灵活的，适合于盒式磁带。曝光技术也类似，尽管拍摄时间往往更短。“检索和处理”阶段也与传统电影有一些相似之处，因为两者都会产生一种“潜影”，在产生结果之前必须对其进行处理。
CR程序管理中存在一些隐藏的因素，但射线照相结果主要取决于技术人员执行测试的技能。如果使用适当的设备和设置，CR甚至能够产生与胶片一致的结果。这就是CR的两大障碍：设备选择和技术人员培训。
Which Computed Radiography System Do I Choose?
并不是所有的检测设备创建equal. In fact, CR equipment is generally engineered with a specific use in mind. That means the options on CR equipment can vary greatly from brand to brand and model to model. Some are designed with the highest of resolution in mind which makes them perfect for specific jobs but may limit their usefulness in other applications. Other units are engineered for ease of use with minimal training. An idea that makes repeatability simple but can also take away important system settings, limiting its usefulness.
Which system is right for you? That is another simple question with a complicated answer. Only an appropriately qualified NDT consultant can answer that question and only after seeing your operation. High resolution and little technical training sounds like an ideal option, but those don’t exist on just one unit.
Like most things in life, there are trade-offs made from one factor to another. High adjustability options generally mean more training to learn their uses. Little adjustability may mean less training for technicians, but also puts a limit on usefulness. Likewise, portability generally puts limits on the equipment’s physical size, potentially limiting the size of images produced. Equipment selection depends on many factors, all of which play a small, but noticeable part. Choosing the wrong CR scanner could mean the difference between an effective operation and a six-figure paper weight.
Technicians Need Proper Training in Computed Radiography Systems
无论您选择哪种扫描仪，培训都是必须的。制造商提供各种费用的培训包，我认为这是绝对必要的。这些软件包通常至少概述了正常操作、支持选项、基本校准和设备维护。它们不应被视为包罗万象。一个全面的补充培训计划是必要的，以通知技术人员雇主的具体操作。
不幸的是，这些项目在这个行业里并不多见。我的经验告诉我，只有少数无损检测供应商在我的地区谁有一个内部培训计划的CR像布朗Intertec。它的成本太高，开发和实施，许多公司要考虑。大多数无损检测供应商依靠技术人员来整理他们自己的培训，这是一种“把他们扔进狼群”式的经验。我知道这一切，因为这是我第一次在CR的经验。该网站有一个CR系统，我被派去学习我自己的单位。如雷竞技好Newbee赞助商果这听起来令人震惊，只需知道服务提供商每天都在做这件事，同时希望客户买单。
As a result of this unstructured system, some technicians have gotten to the point of frustration where they tell the client that CR just can’t be done. When in reality, if they had the proper training, CR could have been implemented. This gap in program structure leaves more and more fabricators, constructors, foundries, and other manufacturers behind the curve with CR. While the industry takes off in a new direction, those service providers are leaving their clients with old techniques that are becoming antiquated.
NDT服务提供商通常是最佳选择
咨询可以是一个良好的CR项目的良好开端，但我的许多读者聘请了一家服务提供商，如Braun Intertec，来管理他们的NDT。在这种情况下，一点小小的研究可以大有帮助。如果您按照某个代码构建设备，它将指定NDT要雷竞技好Newbee赞助商求或为您提供另一个NDT代码。它可能需要几个步骤，但是您会发现认证、CR系统鉴定和系统维护的所有要求。任何已经运行NDT程序的人只需要研究你应该已经知道的文件。无论您是客户还是无损检测服务提供商，我们都有责任为客户和最终用户提供符合要求的产品。少一点是不能接受的。
