3DV+TPS Software Outlines the Radiotherapy of Nasopharyngeal Carcinoma

Study Overview
=================
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.

Detailed Description
-----------------
Comparing the accuracy and speed difference between 3DV+TPS software and imported TPS and domestic TPS to outline the contours of crisis organs, the selected organs are: bilateral eyeballs, bilateral crystals, bilateral optic nerves, bilateral parotid glands, oral cavity, spinal cord, brainstem, The brain has a total of 12 organs; verify that 3DV+TPS is superior to domestic TPS, and has non-inferiority compared with imported TPS, Ming software can improve the accuracy and speed of contour sketching, reduce the burden on doctors, and improve medical efficiency.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| 3DV+TPS<br>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. | Device: 3DV+TPS；VARIAN TPS；FonicsPlan<br> <br> |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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 |
