Abstract:
1. A magnetic resonance imager comprising: a control unit that controls a pulse sequence according to which a radiofrequency magnetic field and magnetic field gradients are applied to a living body lying down in a static magnetic field in order to detect a magnetic resonance signal induced in the living body; and a processing unit that handles the signal, wherein: the control unit (1) controls the pulse sequence to be applied for performing radial scanning, (2) acquires image echoes by applying the pulse sequence a plurality of times, and (3) acquires reference echoes, each of which lies among image echoes in a k-space, by applying the pulse sequence a plurality of times; and the processing unit (1) divides the image echoes and reference echoes into a plurality of groups, (2) uses the reference echo and image echoes preceding and succeeding the reference echo to calculate an estimation coefficient, and (3) uses the estimation coefficient to estimate unmeasured echoes lying among the image echoes in the k-space.
