在“读”取大脑功能状态方面,功能性超声成像则通过检测神经活动引起的微小血流变化,来推断脑区活动状态。不过,当前超声脑机仍面临诸多挑战,显著的一个物理局限在于“时间分辨率”。由于血液动力学反应滞后于电信号放电,功能性超声成像读取到的血流信号天然存在1-1.5秒的延迟,这限制了其在实时高频交互(如即时控制机械臂等)场景中的应用。

The company’s most ambitious system, FLASHDEEP, is still under development. The 13.5-meter-long electron source will deliver very high-energy electrons of as much as 140 MeV up to 20 centimeters inside the body in less than 100 milliseconds. An integrated CT scanner, built into a patient-positioning system developed by Leo Cancer Care, captures images that stream directly into the treatment-planning software, enabling precise calculation of the radiation dose. “Before we actually trigger the beam or the treatment, we make stereo images to verify at the very last second that the tumor is exactly where it should be,” says Theryq technical manager Philippe Liger.
