SBIR TOPIC 106, FAST-TRACK - ACTIVE MRI NEEDLE

针进入深层器官是许多导管、放射和外科手术（诊断和治疗）中常见的，包括进入血管、心包和心腔、内脏等。MRI操作提供了超出X射线透视、CT和超声引导所能提供的精致成像和软组织描绘。 仅通过其材料特性可视化的“被动”针提供了进入和围绕精确或珍贵结构的不充分的跟踪和可视化。 “有源”MRI导管器械包含实现MRI可见性的电子元件。

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.
