When scanning a document printed on both sides by using an electronic scanner, the printed material on the back (front) side may be transmitted to the front (back) side. This phenomenon is called show-through. The problem to remove the show-through from scanned images is called the show-through removal in the literature.

The mechanical properties of the myocardium in the left ventricle and right atrium were estimated by simultaneously measuring the local impedance (LI) and contact force (CF) using an ablation catheter. Radiofrequency catheter ablation (RFCA) is a well-established arrhythmia treatment. Monitoring the RF power, CF and properties of myocardium during RFCA are necessary to estimate the effect of ablation.

Article Synopsis
  • The study investigates how the angle of catheter contact affects local impedance (LI) and lesion size during radiofrequency catheter ablation (RFCA) using two different catheters in a porcine model.
  • It was found that higher contact forces (CF) led to increases in both LI rise and drop, but angle impacts varied between the two catheters, with significant differences observed at a 90° angle compared to 30°.
  • Ultimately, while the LI drop and lesion widths were smaller at a 90° contact angle, the depths of the lesions remained consistent across all angles evaluated.
