PROBLEM TO BE SOLVED: To properly specify a position of a plasma irradiation liquid injected into a body.SOLUTION: The plasma irradiation liquid contains air bubbles. When the plasma irradiation liquid is injected into the body, the air bubbles in the plasma irradiation liquid are detected by a supersonic inspection apparatus. In more detail, because of a characteristic of an ultrasonic wave of being easily transmitted in liquid and a solid and not easily transmitted in gas, when an object organ is imaged by the ultrasonic wave inspection apparatus, an image of the organ is clear and an image of the plasma irradiation liquid, containing the air bubbles, is unclear due to presence of the air bubbles. Therefore, it is determined that the plasma irradiation liquid reaches the object organ, when an operator starts monitoring of the image of the organ before the injection of the plasma irradiation liquid into the body and the image of the organ displayed in a monitor becomes unclear after the injection of the plasma irradiation liquid into the body. Thus, it becomes possible to properly specify the position of the plasma irradiation liquid injected in the body.SELECTED DRAWING: Figure 4 |
