VOA常速英语:Can Artificial Intelligence Help Doctors Make Better Decisions?

This is a classroom for artificial intelligence or AI.It’s teacher Rishi Rawat is feeding the computer more samples of cancer cells.It’s there like a computer brain and you can put the data into them
这是人工智能或者AI的教室。Rishi Rawat老师正在给计算机提供更多的癌细胞样品。它就像一个计算机大脑，你可以将数据录入，

and they will learn the patterns and the pattern recognition that’s important for making decisions.Decisions by doctors to determine the best treatment for their patients.Machines are not going to take over the place of doctors.Computers will not treat patients, but they will help make certain decisions and look for things that the human brain can’t recognize these patterns by itself.
计算机可以学习这些模式、模式识别，这对做决策非常重要。医生帮助患者确定最佳治疗方案。机器不会取代医生。计算机不能治疗患者，但是可以帮助作出某些决策，并且寻找某写人类大脑无法识别的东西。

For example, once a cancerous tumor is removed from a patient with breast cancer，the doctors still have to treat the patient to reduce the risk of recurrence.The type of treatment depends on the type of cancer and whether the tumors driven by estrogen.
举个例子，即使患有乳腺癌的患者体内的癌性肿瘤已经移除了，医生仍然需要给患者提供治疗，以降低复发风险。治疗的类型取决于癌症类型，以及肿瘤是否受雌激素驱动的。

So what the pathologist has to do is to count what percentage of the cells here are brown versus what percentage are not. This process could take days or even longer.In developing nations, they don’t necessarily have access to do this at all,and so there’s a great need there to be able to diagnose these cancers correctly.The computer can do something better than just count cells.AI can recognize complicated patterns on how the cells are arranged,
因此，病理学家需要做的是计算这里的棕色和非棕色细胞的百分比分别是多少。这个过程可能需要数天甚至更长时间。在发展中国家，他们不一定能够完全做到这一点，因此他们非常需要正确诊断这些癌症。计算机可以做的不仅仅是计算细胞。人工智能可以识别细胞排列的复杂模式，

with the hope in the near future of making a quick and more reliable diagnosis that is free of human error.Are they disordered? Are they in a regular spacing? What’s going on exactly with the arrangement of cells in the tissue?We can do this instantaneously for almost no cost in the developing world.Scientists say the time is ripe for the marriage between computer science and cancer research.All of a sudden we have the computing power to really do it in real time.We have the ability of scanning a slide to high enough resolution so that a computer could see every little feature of the cancer.So it’s a convergence of technology.We couldn’t have done this; we didn’t have the computing power to do this several years ago but now it’s all changed.The research now was on breast cancer,but doctors predict artificial intelligence will eventually be used to help treat patients with all forms of cancer.
在不久的将来，我们有望能够快速、可靠作出诊断，而又同时避免人为的错误。它们排列混乱了吗？它们的间隔是否均匀？组织中细胞的排列究竟与什么有关？在发展中国家，我们可以几乎不花任何费用做这件事。科学家们表示，是时候将计算机科学与癌症研究结合了。突然之间，我们拥有了实时运行的计算能力我们能够将幻灯片扫描到足够高的分辨率，以便计算机可以看到癌症的每个细微的特征。所以这是技术的融合。我们不可能做到这一点，几年前我们没有计算能力，但现在情况已经完全改变了。现在的研究是关于乳腺癌，但医生预测，人工智能最终将用于帮助治疗各类癌症患者。
