摘要： A magnetic resonance imaging apparatus according to an embodiment includes a first acquiring unit, a second acquiring unit, and a combining unit. The first acquiring unit is configured to acquire data by executing a pulse sequence based on a first radio-frequency pulse transmission condition. The second acquiring unit is configured to acquire data by executing a pulse sequence based on a second radio-frequency pulse transmission condition that is different from the first radio-frequency pulse transmission condition. The combining unit is configured to perform a combining process either on the data acquired by the first acquiring unit and the data acquired by the second acquiring unit or on data obtained by reconstructing the data acquired by the first acquiring unit and data obtained by reconstructing the data acquired by the second acquiring unit.

摘要： In a flash lamp 1, a front end part 62 of a cathode 60 and a front end part 72 of an anode 70 are opposed to each other on a reference line RL, and with respect to a reference surface RS including the reference line RL, a front end part 82 of a trigger electrode 80 is located on one side, and a front end part 92 of a trigger electrode 90 is located on the other side. Further, a terminal end 82a of the front end part 82 of the trigger electrode 80 and a terminal end 92a of the front end part 92 of the trigger electrode 90 are separated from the reference line RL, and each front end part 82, 92 is formed so as to taper toward the reference line RL. Accordingly, an arc discharge occurs in a limited route R from a terminal end portion of the front end part 62 of the cathode 60 through a terminal end portion of the front end part 82 of the trigger electrode 80 and a terminal end portion of the front end part 92 of the trigger electrode 90 to a terminal end portion of the front end part 72 of the anode 70.
