Real-Time Detection of the Flexible Needle Shape by Using Strain Gauges

Article Preview

Abstract:

In flexible needle insertion procedures, the needle path tracking plays a crucial role in the trajectory control. In this paper, a methodology is proposed to detect the shape of the flexible needle in real time by using the strain gauge sensing. The curvature information of the flexible needle can be obtained based on the stain signal of the gauges which are glued on the needle body markers. Based on this basic approach, the trajectory of the needle can be calculated and displayed, which integrates the discrete markers curvature information. The work reported in this paper indicates a practical significance in the smart medical system implementation without medical imaging equipments.
