PROBLEM TO BE SOLVED: To display new information representing the character of tissue. SOLUTION: In this device, a receipt signal is converted into a complex signal in an orthogonal detection circuit 16. In a divider 26, a real part in the complex signal is divided by an imaginary part, while in a divider 28, the imaginary part is divided by the real part. On the basis of the output from the divider 26 or 28, a B mode image or an M mode image is formed. A ratio of the real part to the imaginary part. is related to phase information contained in a reflection signal, and by means of the ratio, new disease diagnostic information can be provided. |
