Robotic Tools Could Revolutionize Cancer Screening
机器人用于筛查癌症
This robotic arm could revolutionize breast cancer screening.European researchers are developing an automated biopsy tool that could lead to earlier diagnosis of the disease.Their research project called Murab combines data from sensitive magnetic resonance imaging with the speed of real-time ultrasound scanning.
这种机器人手臂可以彻底改变乳腺癌筛查的现状。欧洲研究人员正在研发一种自动活检工具，用于癌症早期诊断。他们的研究项目Murab将磁共振成像的数据与实时超声扫描的速度结合起来。
You have the benefit of both worlds.If you combine the data, at first, we are going to combine it,and then we are going to improve the localization based on modeling because the tissue is deforming.
“这两方面各有长处。如果我们首先把数据同超声扫描加以结合，那么我们就能根据建模进行精确定位，识别变形组织。”
Because breast tissue changes shape as the ultrasound scanner moves over it, researchers say locating the tumor can be a challenge.The ultrasound probe locates the tumor in real time and places the biopsy needle holder directly over it.A radiologist inserts the needle manually while the robotic arm keeps it aligned.
因为超声波扫描仪在移动时，乳腺组织的形状会发生一定改变，研究人员表示，定位肿瘤是一项挑战。超声波探头能实时定位肿瘤，并将活检针直接置于肿瘤之上。放射科医生之后需要在机器人手臂保持对准时手动插入针头。
The researchers say this innovative technique processes the data from the scans to construct a virtual 3D model of the area of the body under investigation,which means that small tumors, not visible to conventional ultrasound imaging techniques can be targeted.
研究人员表示，这项创新技术可以处理扫描数据，构建一个研究特定身体部位的虚拟3D模型，也就是说，这项技术可以用于检测在常规超声成像技术下看不见的小肿瘤。
The researchers believe the ultra precise targeting of tumors may lead to earlier, faster detection and treatment of breast cancer."The goal is in four hours to do the whole clinical workflow, which you do not spend many weeks on it to really have the diagnosis comfort.And we directly take the tissue sample with the robotic arm with higher position than when you are doing the manual biopsy."
研究人员认为，肿瘤的超精确靶向治疗技术会有助于更早、更快地检测和治疗乳腺癌。“我们的目标是在四个小时内完成整个临床工作流程，患者不需要花费几周的时间来等待诊断结果。我们直接用机器人手臂采集组织样本，其位置比手动活检时更高。”
The team hopes the technology can reduce breast cancer deaths and help diagnose other types of cancers where tissue samples are needed.They plan to begin clinical trials using a small group of test subjects next year.
该团队希望这一技术能有助于减少乳腺癌死亡病例，并帮助诊断需要采集组织样本的其他类型的癌症。他们计划明年小范围临床试验该技术。
