Computer Aided Planning of Lithotripsy

In collaboration with

Prof. George Thalmann (Urology, Inselspital Bern)

Extracorporeal shock wave lithotripsy applies strong focused, high-intensity ultrasound waves to gradually destroy kidney stones. Throughout the intervention, a number of such pulses is applied synchronous to the patients heart beat. The guidance of the pulse application system is controlled by X-Ray. By intra-interventional registration of CT images with the X-Ray and guidance of the pulse a highly precise energy application can be achieved.
