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 the target duration, the time-dependent change in a condition where a smaller amount of the contrast medium than the amount of the contrast medium used in the simulation is in…
