The invention relates to an interventional system (1) for performing an interventional procedure. An interventional instrument (5) like a catheter comprises a bendable portion (12), which is bendable by a bending element (11), and an OSS fiber (10) for generating OSS signals being indicative of the degree of bending of the bendable portion. The actual degree of bending of the bendable portion is determined based on the generated OSS signals and the bending element is controlled depending on the actual determined degree of bending. By using OSS, the actual real degree of bending of the bendable portion of the interventional instrument can very accurately be determined. Moreover, since the bending element is controlled based on this very accurately determined degree of bending, the control of the bending element and, thus, of the interventional instrument can be very accurately. |
