Abstract: The simulator includes a chemical liquid information acquisition section configured to acquire an amount of contrast medium, a target value acquisition section configured to acquire a target duration for which a target pixel value is maintained, a protocol acquisition section configured to acquire a contrast medium injection protocol, and a prediction section for determining a predicted duration, the prediction section configured to simulate the time-dependent change in the pixel value in the tissue of the subject based on the injection protocol and the amount of the contrast medium, and the prediction section compares the predicted duration with the target duration to re-simulate, in a case where the predicted duration is shorter than the target duration, the time-dependent change in a condition where a greater amount of the contrast medium than the amount of the contrast medium used in the simulation is injected to redetermine the predicted duration, and in a case where the predicted duration is longer than

Abstract: An image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry obtains a first Magnetic Resonance (MR) image corresponding to a first b-factor and corresponding to each of a plurality of axial directions and to obtain a second MR image corresponding to a second b-factor different from the first b-factor and corresponding to each of the plurality of axial directions. The processing circuitry obtains through a calculation, with respect to each of the axial directions, an MR image as a computed image corresponding to a third b-factor different from the first b-factor and the second b-factor by using the first MR image and the second MR image. The processing circuitry generates a combined image by combining together the plurality of computed images each of which was obtained with respect to a different one of the axial directions.

Abstract: Compositions for low heat cements developed especially for massive concrete works and which exhibit a compressive strength/heat of hydration ratio of at least 7.0 at the age of 13 weeks. One of two inventions provides a powder prepared by mixing CaO, SiO.sub.2, and Al.sub.2 O.sub.3 materials, melting the mixture, quenching the melt, and grinding the quenched matter, the powder being composed mainly of amorphous substances and chemically having a CaO/SiO.sub.2 (molar ratio) of 0.8-1.5 and an Al.sub.2 O.sub.3 content of no more than 10 wt. %. The other invention provides a mixed powder comprising no less than 70 wt. % of a powder and no more than 30 wt. % of an addition (portland cement or the like), the powder being the same as that of the first invention in both predominance of amorphous substances and CaO/SiO.sub.2 (molar ratio) excepting the Al.sub.2 O.sub.3 content which is less than 12 wt. % in the second invention.
