    • The image diagnosis apparatus of the present invention is equipped with means for automatically determining a window level and a window width for image displaying in accordance with the value of reconstructed image data. With this window level/window width calculating means (13), the window level is obtained with respect to each reconstructed image on the basis of the virtual average value of its pixel data and the window width is also obtained which has a certain relationship with that window level. When displaying each reconstructed image, a display is made in accordance with each window level and each window width thus obtained. Instead of the obtained window level and window width, those set by a manual setting section (23) may be used by a changeover operation when necessary.

    • In measuring a number of echo signal, which normally attenuate chronologically, in a single pulse sequence, such as in multi-echo method or a multi-slice method, each echo signal is received and suitably amplified by a reception amplifier having predetermined levels of gain for different time periods during which the successive echo signals are processed such that the echo signals received at a data collection unit are all of substantially the same amplitude regardless of where they appear in the time sequence. The predetermined levels of gains are obtained by false scanning prior to actual image scanning and calculation and storing in a memory. As a result, the echo signals can be received within a dynamic range which is smaller than using the conventional system.
    • 在按照时间顺序衰减的多个回波信号的测量中,以单脉冲序列(例如,以多回波方式或多切片方法)为单位,每个回波信号被接收并由具有预定增益水平的接收放大器适当地放大 在不同的时间段期间连续的回波信号被处理,使得在数据收集单元处接收的回波信号都基本上是相同的幅度,而不管它们在时间序列中出现的位置。 通过在实际图像扫描之前的伪扫描并计算和存储在存储器中来获得预定的增益水平。 结果,可以在小于使用传统系统的动态范围内接收回波信号。
