Home / Fiber Optic Needle Tip Force Sensor
Fiber optic force sensors can be used under MRI without causing any danger or any disruption on the MR image. In this study we investigated several concepts for the design of a force sensor based on a fiber-optic Fabry-Pérot interferometer to measure needle-tissue interaction forces on the tip of a 18 G needle, where special attention was given to concepts for a sensor with (1), an intrinsic low. Experimental evaluation is introduced with insertion in phantoms to reproduce puncture of organs.
This paper presents a novel optical fiber-based needle probe designed to measure the tactile force at needle tip during needle insertions. By fusing the measurements along inserting paths,
