Apparatus and method for determination of the coupling quality between coupling bellow and patients in the case of a device for the extracorporeal treatment with acoustic shockwaves

摘要

Apparatus for the determination of the coupling quality of a koppelbalges (5) of a device for the treatment with acoustic shock waves to a patient (9), comprising:– an optical image recording unit (41, 17), with which an image (35, 43) of a therapeutic formed by a coupling layer (13), via which the bellow to the patient (9) is coupled, can be accommodated, whereby by the picture-taking unit (41, 17) regions with air inclusions (33) in the coupling layer (13) of regions without air inclusions (32) are distinguishable, and– an image processing unit (44), with the with the of the picture-taking unit (41, 17) recorded image (35, 43), a value can be determined, which limits the size of the regions with air inclusions (33) in the coupling layer (13) describes.
