SBIR TOPIC 106, FAST-TRACK - ACTIVE MRI NEEDLE

针头进入深层器官是许多导管、放射学和外科手术的常见方法，包括诊断和治疗，包括进入血管、心包和心腔、内脏等。MRI手术提供了超出X射线透视、CT和超声引导的精细软组织成像和勾画。“被动”针仅仅通过其材料特性来可视化，对精密或珍贵结构及其周围的跟踪和可视化不够充分。“主动”核磁共振导管设备包含电子元件，以实现核磁共振可见性。

Needle access to deep organs is common to numerous catheter, radiological, and surgical procedures, both diagnostic and therapeutic, including access to blood vessels, pericardial and cardiac chambers, viscera, etc. MRI operation affords exquisite imaging and delineation of soft tissue beyond what is afforded by X-ray fluoroscopy, CT, and ultrasound guidance. “Passive” needles visualized solely by their material properties, afford inadequate tracking and visualization into and around precise or precious structures. “Active” MRI catheter devices contain electronic elements to accomplish MRI visibility.
