A system and method for switching from one voltage to another voltage are disclosed. A correction factor may be determined that is based at least in part on a range between the camera and a desired subject. The distal end of the catheter is placed inside the aneurysm. A locally resolved image signal is determined for each of the intermediate signals, G2) by applying a Fourier transformation to the particular intermediate signal, G2). One of the upper extending portion and the lower extending portion is rotated around the bridge portion to form an angular relationship between the planes of the upper and lower portions.
