PROBLEM TO BE SOLVED: To improve the recognition rate of a guide wire in a catheter operation under X-ray radioscopy. SOLUTION: Fine vibration is supplied to the guide wire of a catheter 20 by a guide wire vibration control means 101 and a pixel strongly correlated to a vibration pattern is extracted from an X-ray image and is emphatically displayed on a monitor 10. The recognition rate of the thin guide wire is improved and accurate treatment is performed in a short time. Also, the mental/ physical burdens and X-ray exposure of an operator and a patient are reduced. |
