Research on Improving Radiotherapy Accuracy Based on Image-Guided Radiotherapy

With the changes of people's diet and lifestyle, the number of patients with abdominal malignant tumors is increasing year by year. In order to analyze the effectiveness of cone-beam CT (CBCT) enhancement technology in improving the accuracy of radiotherapy for clinical malignant tumors, 92 patients with abdominal malignant tumor are divided into the control group and the CBCT radiotherapy group. The experimental results show that precise radiotherapy technology can promote the recovery of the immune function of patients with abdominal malignant tumors, improve the effect of treatment, and decrease the incidence of complications.
