%X In this paper, functional imaging PET-CT was used to guide the delineation of esophageal cancer target area, and the accuracy of delineation of esophageal cancer lymph nodes by different images was compared. Pathology confirmed that PET-CT was superior to CT in delineation of lymph nodes. Based on the CT image and PET / CT fusion image, the tumor target area is delineated and the precise radiotherapy plan is made. Based on the PET / CT fusion image, the target area is more accurate and the radiotherapy is more accurate, avoiding the excessive damage of normal tissue. CT combined with PET-CT dual positioning, functional imaging intervention improves the accuracy of target delineation.
