The present invention relates to a treatment apparatus and a control method for the treatment apparatus, and provides a treatment apparatus and a control method for the treatment apparatus, the treatment apparatus comprising: a treatment unit for transferring therapeutic energy at a preset period to a treatment position; a temperature measurement unit for measuring a temperature of the treatment position at a period different from the period at which the therapeutic energy is transferred; and a control unit for controlling an operation of the treatment unit on the basis of a result of measurement by the temperature measurement unit. The present invention enables a user to control a treatment content while accurately understanding the temperature of the treatment position, and thus can improve a treatment effect while preventing thermal damage to tissue.
