影像新技術(shù)：外科醫(yī)生前所未有的法寶（雙語新聞）

When could a video game possibly save your life? A new imaging technology, now being used at Methodist Hospital in Houston, Texas, has direct links to video games. It can provide detailed views of patients’ bodies -- helping surgeons plan and execute complicated operations with much more confidence.

什么情況下視頻游戲可能會救命呢？德克薩斯州休斯頓衛(wèi)理公會醫(yī)院目前正在應(yīng)用的一項新的影像技術(shù)，就與視頻游戲有直接關(guān)系。這項技術(shù)能夠展示病患者體內(nèi)的影像細節(jié)，大大提搞了外科醫(yī)生們設(shè)計和實施復雜手術(shù)的信心。

Those who think that developing video games software has no other purpose than entertainment should think again.

那些覺得開發(fā)視頻游戲軟件除了滿足娛樂需要而沒有其他目的的人，應(yīng)該重新考慮一下了。

So says Dr. Brian Butler, a radiation oncologist at Houston Methodist hospital and the principal author of a new imaging technology called Plato’s CAVE. “Computer engineers and video gamers -- really propelled this type of technology into a possibility,” he said.

布萊恩•巴特勒醫(yī)生是這么認為的。他是休斯頓衛(wèi)理公會醫(yī)院的放射腫瘤科醫(yī)生，同時也是一項名為“柏拉圖洞穴”的新型影像技術(shù)的主要開發(fā)者。他說：“電腦工程師和視頻游戲玩家們讓這類技術(shù)成為可能。”

Multi-dimensional images

CAVE is a powerful processing technology, based on both Microsoft and Apple software, which quickly imports data collected by other imaging machines -- such as CT, MRI and PET scanners -- and converts it into detailed images.

“柏拉圖洞穴”是一項強大的處理技術(shù)，兼容微軟和蘋果操作軟件，它能夠快速地輸入電腦斷層掃描儀、核磁共振掃描儀及正子斷層掃描儀等成像設(shè)備收集的數(shù)據(jù)，并把數(shù)據(jù)轉(zhuǎn)換為詳細的圖像。”

Similar to the graphics in a video game, the multidimensional color images are displayed on a touch-sensitive screen, enabling doctors to manipulate them and virtually “fly” through body parts from all directions, rotate them and zoom in and out.

與視頻游戲中的圖像類似，多維彩色影像會展示在觸摸屏上，供醫(yī)生們操控，簡直就是從各個角度“穿越”患者身體部位，把它們旋轉(zhuǎn)、放大和縮小。

One of the surgeons who uses Plato’s CAVE, Mas Takashima, said being able to clearly visualize the operation area is the key to successful surgery.

另一位使用過該技術(shù)的外科醫(yī)生馬斯•高島說，能夠看到手術(shù)部位清晰的視覺成像是手術(shù)成功的關(guān)鍵所在。

“When you have the data so you can then visualize exactly what's going on, it definitely decreases the stress level or the anxiety level of just wondering, 'oh, is there a possibility that that blood vessel might be, you know, wrapped around this tumor? “ said Takashima.

他說：“當你有了這些數(shù)據(jù)你就可以看到情況到底怎樣，這與只是在想‘哎呀，血管會不會纏在腫瘤上＇的猜測相比，當然減輕了壓力或者焦慮。”

Precision

Recently, surgeons used the CAVE system to plan a difficult operation on a patient who had accidentally shot himself with a crossbow. They were able to clearly see where the arrow entered the skull and how close it was to critical blood vessels.

最近，外科專家們利用“柏拉圖洞穴”系統(tǒng)為一位不小心用弓箭射傷自己的病人設(shè)計了一項復雜的手術(shù)。他們可以清楚地看到箭頭是從哪里射入頭骨，以及離關(guān)鍵的血管有多遠。

But not too long ago, even prominent physicians were skeptical about scanner-imaging technology. Dr. Robert Grossman, who teaches neurological surgery at Houston Methodist Hospital, remembers an experience from 1963.

然而不久前，即使那些有名的醫(yī)生也不相信掃描儀成像技術(shù)。休斯敦衛(wèi)理公會醫(yī)院的神經(jīng)外科醫(yī)生羅伯特•格羅斯曼回憶起1963年的一件往事。

“When the first CT scan was announced, the chief of neuro-radiology at our hospital - he was a very distinguished individual, I won't mention his name - he said to us, 'boys, this is a hoax,'" said Grossman.

他說：“ 當電腦斷層掃描技術(shù)首次被宣布的時候，我們醫(yī)院的神經(jīng)放射科的主任、一個非常出色的醫(yī)生，我就不說名字了，他說，唉，這是個騙局。”

Now, experts say, this is only the beginning. And they say medical imaging technology will get even better as time goes on.

如今，專家們說這只是一個開始。他們說醫(yī)學影像技術(shù)會隨著時間的推移變得越來越高超。
