 Types of diathermy are  Short wave diathermy, Long wave diathermy, Microwave diathermy, Ultrasound diathermy, Laser diathermy. Shortwave Diathermy-Continuous SWD, Pulsed SWD are discussed separately with circuit diagrams and electrodes. Checking of diathermy for power, repair, maintenance , trouble shooting are explained to understand easily.  One equipment is selected and dissected to  explain. Design of SWD and PSWD  -  using  Arduino is explained.

Microwave diathermy (MWD), therapeutic wavelength is 12.25 cm and frequency is 2,450 mega cycles/second. Wave guides conduct microwave energy at lower loss than coaxial cables. The magnetron is a high-powered vacuum tube that works as self-excited microwave oscillator. This system is explained with figures of Magnetron, High voltage circuit and safety since it uses 2KV.
