Glioblastoma multiforme (GBM) represents about 45.6% of primary malignant brain tumors and is marked by rapid growth and resistance to treatment, resulting in a poor prognosis for patients. This study aims to propose a personalized medicine model tailored for patients with GBM with analyzing MRI images and clinical data from 23 patients. Our research encompassed three primary scenarios. In Scenario 1, we constructed a hybrid model combining VIT and Auto-Encoder approaches applied to patient MRI data, achieving an impressive accuracy rate of 96% in determining optimal treatment dosages. For Scenario 2, we introduced Gaussian noise to the MRI images, reflecting real-world conditions, resulting in a drop in model accuracy to 72%. In Scenario 3, we restored the noisy images using advanced techniques, which led to an improved accuracy of 94%. It demonstrates that our proposed scenarios can effectively identify optimal radiotherapy dosages for GBM patients.
