MAGNETIC RESONANCE IMAGING APPARATUS AND METHOD OF GENERATING MAGNETIC RESONANCE IMAGE
First Claim
1. A magnetic resonance imaging apparatus configured to generate an arterial spin labeling (ASL) image, using a 3D balanced steady-state free precession (bSSFP) sequence, the apparatus comprising:
- a signal transceiver;
a sequence controller configured to control the signal transceiver to;
apply an RF pulse and a gradient magnetic field to a first portion of an object;
wait for blood to flow from the first portion of the object to which the RF pulse and the gradient magnetic field are applied, to a second portion of the object;
apply the RF pulse and the gradient magnetic field to the second portion of the object to which the blood flows, using the 3D bSSFP; and
subsample first magnetic resonance data from the second portion of the object to which the RF pulse and the gradient magnetic field are applied; and
an image processor configured to generate label image data based on the first magnetic resonance data.

Abstract
A magnetic resonance imaging apparatus includes a signal transceiver, and a sequence controller configured to control the signal transceiver to apply an RF pulse and a gradient magnetic field to a first portion of an object, wait for blood to flow from the first portion of the object to which the RF pulse and the gradient magnetic field are applied, to a second portion of the object, and apply the RF pulse and the gradient magnetic field to the second portion of the object to which the blood flows, using a 3D balanced steady-state free precession (bSSFP), and subsample first magnetic resonance data from the second portion of the object to which the RF pulse and the gradient magnetic field are applied. The apparatus further includes an image processor configured to generate label image data based on the first magnetic resonance data.
