Patent ID: 7832914

Claim:
A method for positioning an ultrasonic probe on a body surface of a patient using an auxiliary positioning device, said auxiliary positioning device comprising a flexible adjusting member having a first end coupled with a fixing member and a second end coupled with a parallel light source, said parallel light source having a projection hole for passing a parallel light beam emitted from said parallel light source and a cylindrical lens mounted in front of said projection hole for converting said parallel light beam to a fanned light beam, and said method comprising the steps of; fixing said auxiliary positioning device on said ultrasonic probe with said fixing member; defining a correction line on said body surface; marking a surface of said ultrasonic probe with a baseline, said baseline being aligned with a scanning sectional plane of said ultrasonic probe; aligning and placing said ultrasonic probe on said body surface so that said scanning sectional plane, said base line and said correction line are aligned; and bending and adjusting said flexible adjusting member so that a projection line formed by said fanned light beam is aligned with said base line, said scanning sectional plane and said correction line.
