Ultrasonic scan generating method for concrement in body of patient, involves amplifying signals depending on echo depth, such that amplification is increased from depth that is larger than length by process allowing damping in tissue

摘要

#CMT# #/CMT# The method involves generating an ultrasonic scan from a focus region of a shock wave source (18) of a lithotripsy-device with ultrasonic waves that are transmitted and received by an ultrasonic transducer (10), and propagated on a travel path inside a coupling bellow (28) filled with a coupling fluid (33) i.e. water. Length (w) of the travel path is determined. Echo signals received from the transducer are amplified depending on an echo depth (t), such that amplification is increased from the depth that is larger than the length of the travel path by a process allowing damping in a tissue. #CMT# : #/CMT# An independent claim is also included for a lithotripsy-device. #CMT#USE : #/CMT# Method for generating an ultrasonic scan of a concrement in a body of a patient. #CMT#ADVANTAGE : #/CMT# The echo signals received from the transducer are amplified depending on the echo depth, such that the amplification is increased from the depth that is larger than the length of the travel path by the process allowing damping in the tissue, thus generating the ultrasonic scan with good quality and with larger travel path between ultrasonic transducers, and larger boundary surface between the coupling medium and the coupling bellow. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross sectional view of a shock wave head of a lithotripsy-device connected to a body surface of a patient and an ultrasonic transducer arranged in the lithotripsy-device. t : Echo depth w : Length 10 : Ultrasonic transducer 18 : Shock wave source 28 : Coupling bellow 33 : Coupling fluid.
