新技术可能会彻底改变医学成像

New technology could revolutionise medical imaging 
A new miniature scanner that generates highly detailed images in just seconds, could pave the way for more accurate cancer and arthritis diagnoses. Developed by researchers at the University College London, it can deliver imaging scans to doctors in real time. The scanner avoids the risk from X-rays and is smaller than MRI machines but can reveal details neither of them can. Sky's science and technology editor Tom Clarke takes a closer look at the scanner.
一种新的微型扫描仪可以在几秒钟内生成非常详细的图像,为更准确的癌症和关节炎诊断铺平了道路。它由伦敦大学学院的研究人员开发,可以实时向医生提供成像扫描。这种扫描仪避免了x光的风险,而且比核磁共振成像仪小,但可以显示两者都无法显示的细节。天空电视台的科技编辑汤姆·克拉克将带您近距离观察这台扫描仪。

    [1] Yes, please wear the Goggles Signs. - Apart from Goggles to protect against errant laser light. Rob Wilson is about to be scanned with a new technology that's completely harmless, non-invasive, and could revolutionize medical imaging.

    [2] This trial has shown it's particularly good at seeing blood vessels of interest in Rob's case, because he has arthritis that causes painful inflammation in his joints.

  • 3

    [3] "My inflammatory arthritis was being treated. I was not experiencing any symptoms. However, the images did find that there was evidence of active inflammation within the joints of my hand, which potentially could be causing damage, which I was otherwise unaware of."

    [4] The breakthrough here has been miniaturizing something called photoacoustic tomography and taking images fast enough for use in a handheld device. It avoids the risk of x-rays, takes up less space than an MRI machine, and reveals details neither of them can.

    [5] By using very fast pulses of light. - "You heard that clicking sound being fired into the tissues of my hand, and the molecules in my blood vessels are excited by that laser and give out a pulse of ultrasound in response.

  • 6

    [6] And that's detected by another sensor in the device, and that allows them to build up this really detailed image in just a few seconds.

  • 7

    [7] The scanner is fast enough to see dynamic processes like blood flowing through tiny capillaries. The trial showed its potential in patients with diabetes, as well as breast cancer.

  • 8

    [8] "We're able to see very precisely the exact margins of the tumor. So, where the tumor ends and where the normal breast tissue begins."

  • 9

    [9] "That sort of thing would be incredibly useful for planning things like minimally destructive surgery, so just taking out the finest margin around the tumor that you possibly can."

    [10] The researchers need to scan more patients to refine the technology, but say within 5 years it could provide a totally new view inside our bodies. Tom Clark, Sky News.

    是的,请佩戴好Goggles Signs护目镜。 - 除了护目镜,以防止错误的激光。罗伯·威尔逊即将接受一项完全无害、无创的新技术的扫描,这项技术可能会给医学成像带来革命性的变化。

    这项试验表明,在罗伯的病例中,它特别擅长观察血管,因为他患有关节炎,这种关节炎会导致关节疼痛。

    “我的炎症性关节炎正在接受治疗。我没有任何症状然而,图像确实发现我的手关节有活跃炎症的证据,这可能会造成损伤,否则我就不知道了。”

    这里的突破是将一种叫做光声断层扫描的东西小型化,并以足够快的速度拍摄图像,以便在手持设备上使用。它避免了x射线的风险,比核磁共振成像仪占用的空间更小,并且可以显示两者都无法显示的细节。

    通过使用非常快的光脉冲。“你听到咔哒声被射入我的手的组织,我血管里的分子被激光激发,并发出超声波脉冲作为回应。

  • 6

    这被设备里的另一个传感器检测到,这样他们就能在几秒钟内建立起非常详细的图像。

  • 7

    扫描仪的速度足够快,可以看到血液流经微小毛细血管等动态过程。该试验显示了它在糖尿病和乳腺癌患者中的潜力。

  • 8

    “我们能够非常精确地看到肿瘤的确切边缘。比如,肿瘤在哪里结束,正常乳腺组织在哪里开始。”

  • 9

    “这类东西对于规划诸如微创手术之类的事情非常有用,所以只要尽可能地切除肿瘤周围最细微的边缘部分。”

    研究人员需要扫描更多的病人来完善这项技术,但他们表示,在5年内,这项技术将为我们的身体内部提供一个全新的视角。汤姆·克拉克,天空新闻。
