摘要： A method of left ventricular volume evaluation capable of obtaining an accurate evaluation of the left ventricular volume for a heart in an unaffected state. In the method, right anterior oblique image and 4-chamber image of the heart are obtained; using a nuclear magnetic resonance imaging, contours of the left ventricle in the right anterior oblique image and the 4-chamber image are determined; prescribed sets of sizes for the left ventricle are measured from the determined contours; and the volume of the left ventricle is evaluated by using an orthogonal biplane Simpson's method and the measured sizes.

摘要： To prevent crack occurrence at groove bottoms on both side areas of foam rubber tread of all-season studless tires, the pneumatic tire having a tread surface portion composed of at least two outer and inner rubber layers is characterized in that the hardness of the inner rubber layer lies from 54 to 80 degrees in Shore hardness and is higher than that of the outer rubber layer, and further the outer rubber layer is made of foam rubber with a foam rate from 5 to 50% with at least 10% volume ratio with respect to tread volume. The outer foam rubber layer serves to improve tire performance on icy and snowy roads in winter, and the inner ordinary rubber layer serves to reduce change in groove width after vulcanization, that is, reduce dynamic strain concentration at lateral grooves and therefore to reduce crack generation at the lateral groove bottoms.

摘要： A nuclear magnetic resonance imaging for measuring a speed of a flowing target object, capable of determining the speed of the flowing target object accurately, even for the high speed flowing target object. Timings for an application of a pre-saturation pulse to a saturation plane producing a saturated portion within the flowing target object and an execution of an imaging pulse sequence to collect NMR signals from a desired imaging region containing a saturation plane and the saturated portion are controlled to realize a single slice multi-phase pulse sequence, at each phase of which an application of the pre-saturation pulse is followed by an execution of the desired imaging pulse sequence. The speed of the flowing target object is then determined by measuring a distance between the saturated portion and the saturation plane in each reconstructed NMR image, and dividing the measured distance by a time interval between an application of the pre-saturation pulse and a reception of the NMR signals in the single slice multi-phase pulse sequence.
