What heat transfer method does diathermy primarily use?

• A. Conduction
• B. Convection
• C. Radiation
• D. Evaporation

Answer: (B)

Diathermy heats tissue from inside by delivering high-frequency electromagnetic energy. The tissue absorbs this energy and converts it to heat through dielectric heating, which is a radiant form of heat transfer. This means the heat originates from the electromagnetic waves emitted by the device and is not primarily due to direct contact (conduction), fluid movement (convection), or a phase change (evaporation). So the main heat transfer method is radiation.
