Deflection measurements using MR imaging while energizing the catheter solenoid, with two techniques of measuring angular catheter deflection (A-B). (A) Deflection angles measured using most distal visible point of the catheter (linear regression fit with, R2: 0.99 for rheostat and 0.98 for control system). (B) Angles of deflection measured using the center of catheter MRI artifact (linear regression fit with, R2: 0.99 for rheostat and 0.98 for control system). The deflection angle data points are presented as means and standard error of the means, calculated from n = 5.
