Apparatus and method for displaying or determining the coupling bellow between Ankoppelgüte and patient in an apparatus for treatment with acoustic shock waves.

摘要

The invention relates to a device for displaying or determining the Ankoppelgüte a Koppelbalges (5) to a patient (9) in an apparatus for treating with acoustic shock waves, wherein the coupling bellow (5) via a formed from a coupling gel coupling layer (13) to the patient is coupled, comprising the following components: an optical imaging unit, with a picture of the coupling layer (13) is receivable, which are distinguishable receivable by the image recording unit areas with air pockets in the coupling layer (13) from areas without air pockets, and a display unit, with can be represented captured by the image pickup unit image or an image processing unit with which, in the image taken by the image pickup unit, a value is determined that describes the size of the regions with air pockets in the coupling layer (13).
