<P>PROBLEM TO BE SOLVED: To provide a thermotherapy apparatus capable of appropriately cooling down organic tissue by controlling the temperature of cooling water highly precisely. <P>SOLUTION: The thermotherapy apparatus comprises a difference value calculating means 42 for calculating the difference value between the measured value of water temperature obtained by measurement and the predetermined set temperature, a temperature control parameter storage means 44 for storing the temperature control parameter composed by interrelating the calculated difference value and the control value for controlling a cooling part 32 for adjusting the temperature of cooling water for cooling a laser irradiation device, and a control means 43 for controlling the cooling part 32 based on the stored temperature control parameter. The quantity of variation of the control value in the temperature control parameter is different whether the difference value is positive or negative. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
