摘要：
The present invention falls within the field of medical equipment quality inspection. Disclosed is a method for preparing a general-purpose MRI phantom material and a method for preparing a general-purpose MRI phantom. In the method for preparing a general-purpose MRI phantom material of the present invention, a ratio formula is established, wherein according to preset T1 and T2 values of the MRI phantom, the ratio of a desired material corresponding to a given T1/T2 value can be directly calculated, and the range in which the T1/T2 value can be adjusted is large. The method for preparing a general-purpose MRI phantom of the present invention comprises: according to preset T1 and T2 values of an MRI phantom and the volume of water, taking a prepared MRI phantom material and adding water thereto and mixing same, heating and dissolving same multiple times by means of microwaves, and placing same in an MRI phantom carrier to remove air bubbles by means of ultrasonic waves. In the method for preparing a general-purpose MRI phantom of the present invention, a phantom material can be directly configured as needed, making the efficiency high； heating is performed multiple times by means of a microwave oven, and therefore, the time consumption is short and less water is evaporated； there is no need to filter residue, and the concentration of a solution does not change； and ultrasonic waves are used to remove air bubbles, making operation simple.La présente invention se rapporte au domaine du contrôle de la qualité des équipements médicaux. L'invention concerne un procédé de préparation d'un matériau fantôme d'IRM universel et un procédé de préparation d'un fantôme d'IRM universel. Dans le procédé de préparation d'un matériau fantôme d'IRM universel de la présente invention, une formule de rapport est établie selon des valeurs T1 et T2 prédéfinies du fantôme d'IRM, le rapport d'un matériau souhaité correspondant à une valeur T1/T2 donnée peut être directement calculé, et la
