Embodiment Construction

[0041] The described exemplary embodiments relate to extracorporeal shock wave lithotripsy (ESWL), and in particular to the monitoring / monitoring of the coupling interface between the treatment head of the lithotripter and the patient's body, in order to detect changes in the coupling quality, and then, when the change exceeds The operator is notified in the event of a predetermined threshold. Those skilled in the art will appreciate that the invention is not limited to the shock wave lithotripter described in the particular example, but is equally applicable to other therapeutic devices using any other suitable source of acoustic energy (eg shock waves, ultrasound).

[0042] Certain terms are used in the following description for convenience only and not for limitation. In particular, it should be understood that the terms "determine", "calculate" and "account" and variations thereof are used interchangeably and include any type of method, procedure, mathematical operation or...

Abstract

The invention provides a method for continuously monitoring the coupling quality of a coupling interface between an acoustic energy source of a treatment device and a body surface area of a patient. The method comprises the following steps: (f) acquiring a plurality of images of at least one predetermined first area of the coupling interface; (g) extracting at least one first image feature of a predetermined first image of the plurality of images; (h) extracting the at least one first image feature of at least one second image of the plurality of images, the at least one second image being temporally spaced apart from the predetermined first image; (i) determining a quantification parameter corresponding to a difference between the at least one first image feature of the predetermined first image and the at least one first image feature of the at least one second image, and (j) enabling a signal if the quantification parameter exceeds a predetermined reference threshold.

Description

technical field [0001] The present invention generally relates to the field of therapeutic devices utilizing acoustic energy, and more particularly to the process of monitoring the coupling quality and detecting changes in the coupling quality between a treatment head of a therapeutic device and a patient's body. More specifically, the present invention relates to extracorporeal shock wave lithotripsy (ESWL) and an automated method for monitoring the coupling quality of an acoustic coupling interface between a shock wave therapy head and a patient's body. Background technique [0002] In extracorporeal shock wave lithotripsy (ESWL), clots such as, for example, urinary or gallstones are broken up by focused shock waves. ESWL is now the standard of care in the field of urolithiasis, mainly competing with uretero-nephroscopy and percutaneous nephrolithotomy as alternative treatments. Therapeutic devices utilizing other acoustic energy sources, such as for example focused or hi...
