Abstract：This study explores thecurent status ofcalibration management of medical CTand magnetic resonance equipmentin Shandong province.Byanalyzingtheroutineverificationdataof medicalmetrology equipmentin Shandong province in 2O24，it was found that the initial inspection passrates of medical CT machines and magnetic resonance equipment were 93.71% and 94.87% respectively.After reexamination，the pass rates increased to 99.84% and 99.63% （204号 respectively.TheimpactofCTvalueerrors，image noise，scanninglayerthicknessaccuracy，signal-to-noiseratioand uniformityonequipment quality isanalyzed，and improvement measures suchas strengthening equipment management， optimizingcalibrationprocesses，introducing new technologies，andestablishing provincialcalibration centers are proposed.By implementing improvement measures，it is beneficial to enhancing the equipment qualificationrateand management level， providing a solid guarantee for precision medicine.
