摘要： PROBLEM TO BE SOLVED: To reduce working burdens on an operator by setting a trigger level suitable for the amplitude of respiration signals because the trigger level is set based on the amplitude of the respiration signals.SOLUTION: Information representing the value of a window coefficient F is input before execution of a pre-scan A, and the window coefficient F is set. Then, the position when a subject finishes exhaling is set as a reference level Pfrom a respiration signal of the subject. Next, an amplitude D of the respiration signal S and a window coefficient F are substituted in an expression W=D×F to calculate a window width W. After calculating the window width W, a position separated from the reference level Pby the window width W is set as a trigger level TL.
