Abstract
An apparatus, method and system for classifying a shockwave is described, particularly for use in an Extracorporeal Shockwave Lithotripsy (SWL) system. The method for classifying a shockwave generated and directed towards a stone in an extracorporeal shockwave lithotripsy treatment comprises receiving an acoustic signal at a passive unfocused acoustic sensor, determining whether at least one characteristic of the received acoustic emissions exceeds a respective pre-determined threshold value, and classifying the shockwave as effective or ineffective in dependence upon said determination. A method for predicting the outcome of an SWL treatment is also described.
Claims25
A method for classifying a shockwave generated and directed towards a stone in an extracorporeal shockwave lithotripsy treatment, the method comprising;
- receiving an acoustic signal at a passive unfocused acoustic sensor;
- determining whether at least one characteristic of the received acoustic emissions exceeds a respective pre-determined threshold value;
- and
- classifying the shockwave as effective or ineffective in dependence upon said determination.
A system for classifying a shockwave generated and directed towards a stone in an extracorporeal shockwave lithotripsy treatment, the system comprising;
- a passive unfocused acoustic sensor for receiving an acoustic signal following generation of the shockwave;
- a characteristics determiner for determining whether at least one characteristic of the received acoustic emissions exceeds a respective predetermined threshold value;
- and
- a classifier for classifying the shockwave as effective or ineffective in dependence upon said determination.
A computer readable medium having instructions and data stored thereon which, when loaded into and executed by a computer, cause the computer to perform a method of classifying a shockwave generated and directed towards a stone in an extracorporeal shockwave lithotripsy treatment, the method comprising:
- receiving an acoustic signal at a passive unfocused acoustic sensor following generation of the shockwave;
- determining whether at least one characteristic of the received acoustic emissions exceeds a respective pre-determined threshold value;
- and
- classifying the shockwave as effective or ineffective in dependence upon said determination.
