| Abstract(in English) | In ultrasonography, a B-mode image is reconstructed by assuming the speed of sound in living tissues as a constant value. However, a difference between the actual and assumed speeds of sound in the tissues may influence the image reconstruction. In this study, an accuracy on an estimation method for the average speed of sound using a compound ultrasonic imaging is investigated by performing simulation experiments. When maximum transmitted angles were changed, the estimated value was the closest to the true value at a maximum transmitted angle of 12°, and the standard deviation of the estimated value was the most suppressed at a maximum transmitted angle of 10°. |
