Abstract
An object of the present invention is to produce images devoid of band artifacts. Data acquisition in SSFP is repeated N times (where N denotes the power of 2) in order to acquire data fv(k), which ranges from data fv(0) to data fv(N−1), from views v constituting a k-space. At this time, the phase of an RF pulse is varied based on an expression of 360°·v·k/N. If an operator designates Fourier transform imaging, a Fourier transform is performed on data fv(k) relative to each of the phases indicated by the RF pulse in order to produce data Fv(n). If the operator does not designate Fourier transform imaging, the data fv(k) is regarded as the data Fv(n) as it is. Any of at least either of weighted addition and MIP processing and root-mean-square conversion selected by the operator is then performed on the data Fv(n) in order to produce data Av. An image is reconstructed based on the data Av.
