A computational model of open-irrigated radiofrequency catheter ablation accounting for mechanical properties of the cardiac tissue [PDF]
, 2018 Radiofrequency catheter ablation (RFCA) is an effective treatment for cardiac arrhythmias. Although generally safe, it is not completely exempt from the risk of complications. The great flexibility of computational models can be a major asset in optimizing interventional strategies, if they can produce sufficiently precise estimations of the generated ...

Mind the gap: quantification of incomplete ablation patterns after pulmonary vein isolation using minimum path search [PDF]
Medical Image Analysis, 51, 1-12, (2018), 2018 Pulmonary vein isolation (PVI) is a common procedure for the treatment of atrial fibrillation (AF). A successful isolation produces a continuous lesion (scar) completely encircling the veins that stops activation waves from propagating to the atrial body.

Radiofrequency ablation of bone tumours
Diagnostic and Interventional Imaging, 2012 The indications for radiofrequency bone ablation in the case of benign tumours (osteoid osteoma, osteoblastoma) are curative, whereas for bone metastases, the prime aim is palliative analgesia. The failure rate for osteoid osteomas is low (

Optical Hydrogen Sensing Materials for Applications at Sub‐Zero Temperatures
Advanced Functional Materials, EarlyView.This study demonstrates the viability of optical hydrogen sensors at temperatures as low as −60°C. Using advanced metal hydride materials, the sensors detect hydrogen with high sensitivity, speed, and stability across a wide range of concentrations. These findings open doors for safe hydrogen detection in extreme cold, enabling applications in aviation,
