1. An individualized imaging method, comprising: obtaining first image data information of a mould of an object to be imaged; calibrating, correcting and optimizing an imaging system with the first image data information, scanning and imaging the object to be imaged to obtain second image data information by the calibrated, corrected and optimized imaging system; and optimizing the first image data information and the second image data information to obtain an imaging result and data analysis result with a higher quality, wherein the mould of the object to be imaged is made according to density information or function information obtained by an imaging system imaging the object to be imaged, the density information is structure information that a material with the same density as human tissues is utilized to simulate different organs or tissues, the function information is simulated by reserving corresponding space in the mould to add drug taking part in relative function activities.
