a user input device configured to receive a user input for inputting a plurality of time sections and magnetic resonance imaging (MRI) pulses to be generated in each of the plurality of time sections;

a display configured to display a pulse sequence schematic diagram that shows an MRI pulse sequence along a timeline that is divided into the plurality of time sections based on the plurality of time sections and the MRI pulses to be generated in each of the plurality of time sections;

wherein the user input device is further configured to receive a user input that relates to selecting a first point on the pulse sequence schematic diagram; and

a processor configured to determine a time section from among the plurality of time sections and a first area corresponding to the determined time section in the pulse sequence schematic diagram based on coordinates of the selected first point, and control the display to identify the determined time section from among the plurality of time sections by displaying an image representing the first area on the first area.
