摘要

The invention relates to the use of an A-mode ultrasound system for monitoring the position of a patient during a therapy session, as well as a method and apparatus comprising the application thereof. The therapy apparatus comprises a therapy device (12) comprising at least one ultrasound therapy transducer (14) and at least one ultrasonic surveillance transducer (16), characterized in that the ultrasonic monitoring transducer is an A mode ultrasound transducer forming part of an A mode ultrasound machine, said apparatus also comprising means (24,28) for transmitting a short signal to the A mode ultrasonic transducer for receiving echoes of this signal on said transducer in mode A, means (28) for comparing the echo received with respect to a reference echo and means (28) for transmitting the result of this comparison to a control device (40). BR/ Therapy monitoring can be automatic. / P
