Abstract: Abstract Background: Radiofrequency ablation (RFA), a method of inducing thermal ablation (cell death), is often used to destroy tumours or potentially cancerous tissue. Current techniques for RFA estimation (electrical impedance tomography, Nakagami ultrasound, etc.) require… read more here.

Abstract: The accuracy and safety of lesions created during catheter ablation of cardiac tissue rely on the user's ability to predict the size of lesions that form under variable conditions during treatment. A user-directed robotic system… read more here.

Abstract: OBJECTIVES Atrial fibrillation is treated surgically by creating conduction block lesions. Radiofrequency (RF) lesions have reduced efficacy compared to 'cut-and-sew'. Catheter ablation studies demonstrate a relationship between lesion depth and contact force. We hypothesized that… read more here.

DOI: 10.1364/boe.451547
Abstract: Atrial fibrillation (AF) is a rapid irregular electrical activity in the upper chamber and the most common sustained cardiac arrhythmia. Many patients require radiofrequency ablation (RFA) therapy to restore sinus rhythm. Pulmonary vein isolation requires… read more here.
