    摘要: A magnetic resonance imaging apparatus includes a trigger generating unit, a blood flow image generating unit and a control unit. The trigger generating unit acquires blood flow information of an object and generates a trigger based on the blood flow information. The blood flow image generating unit acquires imaging data with using the trigger and generates blood flow image data. The control unit controls so as to repeatedly perform a probe sequence for acquiring the blood flow information and an imaging sequence for acquiring the imaging data alternately.

    摘要: An MRI system includes static and gradient field generators for respectively generating static and gradient fields to be applied to an object, a radio-frequency (RF) field transmitter/receiver for transmitting and receiving an RF field, a sequence controller for applying the gradient field and the RF field to the object at a predetermined timing while the object is being applied with the static field, thereby causing a predetermined MR phenomenon, a signal processor for performing predetermined processing of MR signal data detected through the RF field transmitter/receiver to obtain an MR image, and a display for displaying the image obtained by the signal processor. The sequence controller comprises a multi-slice controller for executing a multi-slice method using a sequence with a relatively long echo time so that an MR signal of a proton of a fat is suppressed and an MR signal of a proton of a CSF is emphasized. The signal processor comprises a summation processor for synthesizing multi-slice images as a plurality of slice images by summation to obtain a synthesized image.

    摘要: A magnetic resonance imaging apparatus includes an acoustic control unit and an image data acquisition unit. The acoustic control unit applies a gradient magnetic field for controlling a sound in synchronized with a signal representing a respiratory body motion. The image data acquisition unit acquires imaging data by imaging subsequently to controlling the sound and generates image data based on the imaging data.
