    • A therapy apparatus has a source of acoustic waves which propagate through a medium in the source, a setting arrangement by means of which a desired distance can be set between a body surface of a patient and a reference point of the source, and an arrangement for determination of the distance of the body surface of the patient from the reference point. The latter arrangement includes a sensor element that is contained inside the source and which can be displaced in the direction of the acoustic axis of the source. The sensor element is in at least indirect contact with body surface of the patient during the determination of the distance. The apparatus also has a display arrangement for providing a quantitative visual indication of the distance.
    • 治疗装置具有通过源中的介质传播的声波源,可以在患者的身体表面和源的参考点之间设置期望距离的设置布置,以及用于 确定患者身体表面距离参考点的距离。 后一种布置包括传感器元件,其被容纳在源内部并且可以在源的声轴的方向上移位。 在确定距离期间,传感器元件至少间接地与患者的身体表面接触。 该装置还具有用于提供距离的定量视觉指示的显示装置。
