1 The characteristics of the 2 dimensional echogram, the color Doppler energy imaging and pulsed 2 wave Doppler ultrasound spectrum were studied.

2 Investigation of the echogram of a liquid cylinder in homogeneous scattering medium is described.

3 The characteristics of the two-dimensional echogram, the color Doppler energy and pulsed-wave Doppler ultrasound were studied.

4 Methods:To analyze retrospectively the echogram hallmarks of 287 cases, and compared with the postoperative pathologic results and the final clinical conclusions.

5 Based on the analyses of the echogram , the pipeline position, the pipeline settling depth and the free-span state can be quantitated.

6 Objective Discusses high frequency ultrasound the echogram characteristic and the clinical practice which organizes in the different time vice-breast.

7 These results enable us to estimate ultrasonic properties of a liquid cylinder by its echogram.
