Abstract: Objective To explore the application value of digital models in doctor-patient communication by applying 3D reconstruction technology to reconstruct the digital model of pituitary tumors. Methods CT and MRI data of 5 patients with pituitary adenoma were imported into mimics 21.0 software in DICOM format to obtain 3D digital model of pituitary adenoma. 32 family members of pituitary tumor patients(one family member for each patient)were recruited and randomly divided into control group(n=16)and experimental group(n=16). The experimental group used 3D model to make statistical analysis on the score data of family members of the two groups. Results The high-fidelity digital model was reconstructed by MIMICS 21.0 software. Statistical analysis showed that after using the model, the patient's family members had a significant understanding of the four aspects of pituitary tumor anatomy(t=4.233, P<0.001), clinical manifestations(t=5.121,P<0.001), complications(t=5.504,P<0.001)and treatment options(t=4.659,P<0.001). Conclusion The 2D image is reconstructed into a digital model with a spatial structure through 3D reconstruction software, which is vivid and intuitive, and can better assist the doctor in the patient's condition notification. At the same time, it is easier for the patient to understand his condition. The effect of doctor-patient communication has been significantly improved, and patients have a higher degree of recognition and cooperation with doctors’ treatment plans.
