Brief Summary
Comparing the accuracy and speed of 3DV+TPS software with imported TPS and domestic TPS to outline the contours of crisis organs, it is proved that 3DV+TPS has superiority compared with domestic TPS, and it has non-inferiority compared with imported TPS, indicating that the software can improve contour sketching accuracy. And speed, reduce the burden on doctors, improve medical efficiency.

Outcome Measures
Primary Outcomes (2)
Sketching accuracy
Define ΔV as a percentage of the total volume of the gold standard;
one year
Sketch speed
Use the stopwatch to record the total time used to draw down 12 organs, to start sketching as the starting point of the time, and to finish the saving of the data.
one year
Study Arms (1)
3DV+TPS
This experiment included a total of 300 patients with nasopharyngeal carcinoma, using 3DV + TPS software and imported TPS, domestic TPS, these three sets of TPS delineate bilateral crystal, bilateral optic nerve, bilateral eyeball, bilateral parotid gland, oral cavity, spinal cord There are 12 organs in the brainstem and brain, and the accuracy and speed of the 3 sets of TPS sketches are compared.
Interventions
Eligibility Criteria
A total of 7 different grade hospital radiotherapy centers have received radiotherapy for patients with nasopharyngeal carcinoma Case information, based on inclusion and exclusion criteria, a total of 300 cases were screened. Among them, Xinqiao Hospital collected 180 cases, He collected 20 cases in 20 hospitals, totaling 200 cases.
You may qualify if:
- It is diagnosed as nasopharyngeal carcinoma by histopathological examination, and there is no tumor invasion in the organs that need to be assessed;
- Age 18-70 years old;
- There is nasopharynx localization enhanced CT, nasopharynx enhanced MRI.
You may not qualify if:
- Patient information is incomplete; no age, gender, MRI, height, radiotherapy location CT;
- The organs at risk that need to be assessed are invaded by the tumor;
