Figure 6. AP Image demonstrating the applied PP AP matrix to objects and overlap in images. Taking formula's 10-12, U (horizontal) and V (vertical) display coordinates are computed for all 3D objects and introduced into the display. Cyan colors show pin tips, pin bases, and the right DBS electrode. Screw tips from the DBS retaining cap were also included here. Anterior commissure (AC), Posterior commissure (PC), and Midline are demonstrated in blue. The left DBS electrode and original trajectory from left STN target, 15 mm above target and 75 mm above target are in green.
