Ultrasounds locating and destroying device for internal human body objects

摘要

Device for locating and destroying objects (19) inside the body by means of ultrasound, consisting of a transducer (1) operated by a pulse generator (3) and generating focused shock-waves, which can be transmitted via a coupling medium to the body of the patient, and of a locating system connected to the transducer (1) and providing an image. The locating system comprises at least one monitor as a display device, on whose screen the object (19) and a target cross (7) can be visualised. The object can be made to overlap with the target cross by means of a relative movement between patient and transducer (1), in order to align the transducer focus with the object and to trigger the operation of the pulse generator (3). A signal level corresponding to the brightness value of the imaged object and obtained from the video signal of the imaging system can be established as a desired value, and a selected target area encompassing the object can be scanned automatically by displacement of the transducer (1). The video signals occurring in this respect in the imaging system as actual values can be compared to the desired value, and the pulse generator (3) can be started up when the level of the actual values is at least the same as the level of the desired value. …IMAGE…
