<p>A probe (10) receives an echo signal, and the echo signal is stored in a memory (18). A control panel (28a) has at least one read range setter (34) for setting an echo signal read sensitivity range of the echo signal stored in the memory (18). Echo signals in the sensitivity range preset by the read range setter (34) is read from the memory (18)from among the echo signals in the overall sensitivity range stored in the memory (18). The echo signal read out of the memory (18) is converted into data corresponding to the display dynamic range of a monitor (24a) by a digital gain adjusting circuit (31). The converted data is inputted into an image structuring section (22) to create image data. The image data is displayed on the screen of the monitor (24a).</p> |
