Title: Ultrasound scanning method and ultrasound diagnostic equipment
Inventor: RI TAHO
IPC: A61B8/00
Filed: 2000-02-28
Abstract: PROBLEM TO BE SOLVED: To perform ultrasound scanning using unipolar driving signals which is similar to ultrasound scanning using bipolar driving signals. SOLUTION: Positive transmitting pulse +S, positive transmitting pulse +S', positive transmitting pulse +S, and positive transmitting pulse +S are sent to the examinee's body in this order. These positive transmitting pulses are basically sent every time time T passes, except for the second positive transmitting pulse +S' that is sent at a half cycle of the ultrasound ahead of time when the other transmitting pulses are sent. Since the positive transmitting pulse +S', which is sent at a half cycle of ultrasound ahead of time, is taken as negative transmitting pulse, the ultrasound scanning method using unipolar driving signals becomes equivalent to that of using bipolar driving signals.
