Math, myth and the fundamentals of electrosurgery

An electrosurgery generator (ESU) is a critical piece of equipment found in every therapeutic endoscopic setting. The high frequency (RF or Radio Frequency) alternating currents produced by these ubiquitous generators provide the thermal energy used for the treatment of gut diseases from polyps to bile duct stones, strictures, tumors and more. A frequent physician complaint is that even though ...

2. Fundamentals of Electrosurgery Part I: Principles of Radiofrequency Energy for Surgery

کاربرد روش معادله سهموی در تحلیل مسائل انتشار امواج داخل ساختمان

With the rapid growth of indoor wireless communication systems, the need to accurately model radio wave propagation inside the building environments has increased. Many site-specific methods have been proposed for modeling indoor radio channels. Among these methods, the ray tracing algorithm and the finite-difference time domain (FDTD) method are the most popular ones. The ray tracing approach ...

Electrosurgical applications in Dentistry

Electrosurgery which can also be called as radiosurgery has been used in dentistry for more than 50years. Electrosurgery is a controlled precise application of radiofrequency electrical current to the soft tissue site to be cut which is achieved by means of carefully designed electrodes. Electrosurgery is used in almost all branches of dentistry. Electrosurgery is a continuously evolving field ...
