1. a prediction contains the fc-specific test FC pill of the contrast agent with known injection flow change procedure in the mobile method of life entity interimage agent in the blood vessel of this life entity, wherein:

  • 1.1. utilize the tomography method comprising a plurality of the observation during measuring finite time section Z constantly and definite contrast agent time-concentration change procedure at least one place in vivo,1.2. from the time-varying process that obtains about the contrast concentration of another time of prediction contrast agent injection the measurement data of contrast agent distribution,It is characterized in that,1.3. in order to predict the contrast agent time-concentration change procedure b of at least one place x that measured in advance in vivo R(x t) adopts a physiological models, 1.4. be similar to measured contrast concentration change procedure based on the following formula of known mobile test pill injection that has at least one place x, and definite function constant A, B, C, c 0;
