Measurement of internal constraints during an interventional radiology procedure.
This paper presents a novel method for measurements of internal constraints during an Interventional Radiology procedure. Fiber-optic strain gauge, operating as a Fabry-Perot interferometer, is inserted and navigated inside a polyvinyl alcohol (PVA) model. The information obtained from deformation of the Fabry-Perot cavity is analyzed and the results are then rescaled through a calibration procedure for catheters. The measures help to locate the maximum interaction forces between catheter and blood vessel wall at approximately 1.3 N and to observe the shape of dynamic interaction during manipulation.
