PROBLEM TO BE SOLVED: To provide an integrated MRI simulation system capable of acquiring a simulation result in a short time.SOLUTION: An MRI simulation system includes an MRI detection part 40 for imaging a subject 43, a virtual MRI detection part 25 for imaging a numerical value phantom 26, an MRI controller 23 for controlling the MRI detection part 40 based on an MRI pulse sequence, an MRI simulator 24 for controlling the virtual MRI detection part 25 based on the MRI pulse sequence, an MRI reconstructor 27 for decrypting an MRI signal output from the MRI controller 23 or the MRI simulator 24 and generating a reconstruction image, and a display part for displaying a first reconstruction image in which the MRI signal from the MRI controller 23 is decrypted and/or a second reconstruction image in which the MRI signal from the MRI simulator 24 is decrypted.SELECTED DRAWING: Figure 2
