Power control mode delivers RF energy (W) to achieve a set temperature (°C). True or False?

• A. True
• B. False
• C. It depends on system
• D. Not applicable

Answer: (B)

In RF ablation, control methods are about how energy delivery is regulated. In power control mode, a fixed wattage (power) is delivered for a chosen duration or until a stop condition is reached. The actual tissue temperature becomes a result of the delivered energy and tissue properties; there isn’t a target temperature being set or actively maintained. In contrast, temperature control mode continuously monitors tissue temperature and adjusts energy to keep the tissue at a chosen temperature.

So the statement is false: power control mode does not deliver energy to achieve a set temperature; that's the job of temperature control mode.
