Superimposed needle targeting is a method of orienting a needle or slender instrument to a desired target specified in a fluoroscopic view. This mimics the way that physicians commonly proceed with manual access under fluoroscopy guidance:
a) Photo of clinical intervention
b) Needle superimposed over target in AP view, c) Lateral view showing needle at calix target
For needle insertion, the C-Arm (fluoroscopy head) is then rotated to a lateral view in order to gain needle depth perception. The needle is inserted (manually or under joystick control) under direct fluoroscopic observation. The method was implemented on the PAKY, RCM and AcuBotX-Ray guided systems.
