PURPOSE:To simplify a processing by optionally designating and displaying an object part. CONSTITUTION:Conventionally, a center frequency and a center phase are fixed and cannot be optically changed, however, they can be changed by an external designation. Namely, the frequency f0' different from the conventional center frequency f0 is designated when extracting data after a high speed Fourier transformation processing in a picture reconstitution processing, thereby, the data of the range of 2DELTAf centering the f0' is stored in a magnetic disk. This is similar in a phase encoding direction. Not only the center frequency and the center phase can be changed but also the size in an extracting area can be optionally changed. |
