| Abstract: | This paper discussed some artifacts and error in ultrasonic B-mode imaging.First of all, the basic model of the artifact caused by multiplex reflection was re-ported. The influence of displaied intensity caused by the incident angle was takenaccount in order to make the model approaching practice. Finally the position andmeasurement error in B-mode display caused by the difference of propagationvelocity in human soft tissue were estimated. The result of computer simulationwere also reported. |
