Surgical diathermy, also known as electrosurgery, is the passage of a high-frequency alternating current through the body to produce a desirable surgical effect. The electrosurgery device market is lucrative and highly competitive. Understanding a few basic principles of electrosurgery physics can allow a surgeon to be a more informed consumer of electrosurgical products.

A type of technology that has shown real worth in the clinical setting is shortwave diathermy, as it can aid greatly in controlling pain and increasing the blood flow to damaged muscle areas. Shortwave diathermy acts with deep heat, as opposed to sound waves. In conjunction with other non medication-based therapies, shortwave diathermy can help a large number of patients with varying degrees of injury, as well as different types of injury.

Just as digital technologies have dramatically improved home audio and video fidelity, flat panel digital X-ray technology offers significant improvement in image quality and dose utilization. The performance of the flat panel detector imagers is rated as the value of DQE (Detective Quantum Efficiency).

As wireless communication becomes more popular, there is increased risk of interference with medical equipment in hospitals. There are several ways to deal with Radio Frequency Interference (RFI), avoiding damage as new technologies emerge.
