Scan condition determining apparatus, magnetic resonance apparatus, scan condition determining method, and program

An MR scan method performed by an MR apparatus, the method comprising:

• setting values of a plurality of parameters for an MR scan other than a repetition time and other than a bandwidth;
• determining a specific value of the bandwidth based on the set values of the plurality of parameters to minimize a repetition time which is the longer one of a first period of time and a second period of time, the first period of time being a time taken to perform a pulse sequence in one cycle, and the second period of time being a time taken from the start of a pulse sequence in one cycle until a pulse sequence in a next cycle is ready to perform, wherein determining the specific value of the bandwidth comprises obtaining the repetition time for the bandwidth assuming each of a plurality of mutually different values and determining the specific value based on the obtained repetition times;
• and
• performing the MR scan according to the specific value of the bandwidth, the minimized repetition time, and the set values of the plurality of parameters.

• wherein determining the specific value of the bandwidth comprises estimating a first curved or straight line representing change of the first period of time with respect to the bandwidth and a second curved or straight line representing change of the second period of time with respect to the bandwidth, and determining a value of the bandwidth corresponding to an intersection of said first and second curved or straight lines as said specific value;
• and
• performing the MR scan according to the specific value of the bandwidth, the minimized repetition time, and the set values of the plurality of parameters.
