摘要： In a measuring space of the object (1), an essential measurement region (41, 61, 71, 81, 111, 131) having a center region of the measuring space and a plurality of peripheral measurement regions (42, 62, 63, 72, 82, 112, 132) which do not have any region overlapped with the essential measurement region are set. Then, the essential measurement region is combined with a selected peripheral portion of the plurality of the peripheral measurement regions to measure in a preceding manner a nuclear magnetic resonance signal from the object as data of the measuring space. The essential measurement region is combined with the peripheral measurement region of the plurality of the peripheral measurement regions which has not been selected in the preceding measuring step to measure a nuclear magnetic resonance signal from the object as data of the measuring space. Sequentially, the essential measurement region is combined with the peripheral measurement region having not been measured in a preceding measuring step to measure a nuclear magnetic resonance signal from the object. The data of the essential measurement region and the data of the peripheral measurement region thus measured is supplemented with the data of the peripheral measurement region measured in the preceding measuring step to generate data of the measuring space.

摘要： A magnetic resonance imaging apparatus is provided with a sequencer for executing a rapid imaging sequence of up to 100 ms at a full scan, a parallel measurement system for executing a partial encoding measurement in which the number of phase encoding operations performed for the measurement is reduced, an image processing system for reconstructing images from the information obtained though parallel measurements and composing reconstructed images of a plurality of areas to make one image, a display system for displaying the obtained images at a rate of 50 frame/second or more, and an image renewal system for taking in coordinate information of the cross-section to be imaged from position and pointing devices at intervals of about 0.1 second, and renewing the cross-section to be imaged in real time. Thus, imaging on the cross-sections indicated by a device can be performed in real time with high spatial and high time resolution.

摘要： An MRI apparatus having a pulse sequence of dynamic MRA performs a pulse sequence for monitoring arrival of a contrast agent at a blood vessel of interest. The pulse sequence is substantially the same as the imaging sequence except that the phase-encode number and/or the slice-encode number is small. A time-series image reconstructed by using data measured under the condition of applying gradient magnetic fields with a low spatial resolution is displayed to ascertain that the contrast agent has arrived at the blood vessel of interest. When the contrast agent arrives at the blood vessel of interest, the phase-encode and slice-encode are added to continue the substantial measurement pulse sequence without changing the pulse sequence itself. The first image of the substantial measurement is produced by using the data acquired at the time of arrival of the contrast agent in monitoring. Thus, the arrival time of the contrast agent can be reliably monitored with high time-resolution and the substantial measurement can be performed with most suitable timing to obtain an excellent blood vessel image.

A membrane-electrode assembly is sandwiched or pinched by the first and second gaskets. The first gasket has a main lip in which a top portion brought into close contact with the membrane-electrode assembly is formed flat. The second gasket has a flat seal portion and a sub lip protruding from this flat seal portion at a position opposing the main lip. The flat seal portion and the sub lip are brought into close contact with the membrane-electrode assembly. The width of the top portion of the main lip is narrower than the width of the flat seal portion, and larger than the width of the sub lip.
