摘要： When multiple types of imaging are performed while moving a table on which a subject to be examined is placed, an imaging efficiency is improved and a high-quality image is obtained within a short time. Therefore, within a predetermined time interval such as an identical period of a periodic living body motion, a predetermined number of echo signals from each of the multiple types of imaging sequences are acquired and the table on which the subject to be examined is placed is moved. Along with the movement of the table, data items within the same range in the Ky-direction as to each of the imaging sequences are acquired, the moving speed of the table is controlled in such a manner that the acquired data items become continuous in the x-direction, and images are reconstructed based on the data items obtained respectively from the imaging sequences.

摘要： It is possible to improve an image quality of an ultrasonographic device and improve visibility of a tissue structure and a lesion. According to a noise amount estimated for each of at least two resolution levels and reliability of the noise amount estimation, a corrected noise amount is calculated. An intensity conversion is performed on a decomposition coefficient obtained by a multi-resolution decomposition process using the corrected noise amount. Moreover, by performing intensity conversion of the respective decomposition coefficients according to a plurality of decomposition coefficients, it is possible to generate a high-quality image. Furthermore, by switching processing parameters in accordance with the imaging condition, the image type, and the imaging object, it is possible to simultaneously realize the processing time and the image quality appropriate for the purpose.

摘要： An ultrasonic imaging device which narrows the width of annular areas to be established, without increasing the number of channels. The controller establishes the annular areas 421 to 42p the number of which is larger than the number of signal lines, along line intersections between wave surfaces 51 to 54 of reflective waves and a multi-dimensional surface of the probe 1. The controller selects multiple annular areas (0, 0), (0, 1), and (0, 2) with focal depths differing, for example, by an integral multiple of the ultrasonic wavelength λ, out of the multiple annular areas being established, and connects the multiple transducer elements positioned within the selected multiple annular areas with an identical signal line. Accordingly, the received signals from the selected multiple annular areas arrive at multiple time points shifted by the time corresponding to the wavelength, and the signals do not cancel one another out.
