Abstract
During transcatheter interventions, correct distance measurements are mandatory for proper device selection. We present a new calibration procedure in which distance calibration is performed with a high contrast metallic rod placed in the esophagus as a scaling device. Distortion related to differences in Calibration and object planes as well as axial angles were analyzed and appropriate correction factors calculated. A cardiac phantom served to test the accuracy and precision of the new measuring system. The mean measurement error was < 1.7% (range 0.1%–4.9%), and the mean measurement variability 1% (range 0.3%–1.9%). The accuracy of angiographic measurements can be significantly improved using a calibration device in the esophagus in combination with appropiate mathematical corrections.
