Abstract
In specific magnetic resonance imaging, magnetization spins are repeatedly excited by excitation pulses, and echoes are repeatedly generated after each of the excitation pulses. The echoes so generated are acquired as echo signals. Based on these echo signals, image data is reconstructed. According to the present invention, the number of times the magnetization spins are excited by the excitation pulses is input by an operator and, based on this input number, the number of echoes generated by one excitation is determined. Image-pickup time can easily be computed on the basis of the number of times of excitation and the time required for repeating fixed excitation pulses. The operator is able to easily control the image-pickup time by controlling the input number of times of excitation.
