| Abstract: | Objective:To study the clinical application of CT-based simulation and evaluate the it's value in the treatment planning of intensity-modulated radiotherapy(IMRT).Methods:49 patients with cancer were underwent multislice spiral CT-based simulation,the CT-scanning imaging of all patients were transferred to three-dimensional treatment planning system(TPS) through cable.The treatment planning of IMRT was performed on TPS and IMRT underwent for every patients.Results:The imaging information of all patients was ideal,the dose distribution were calculated correctly and the optimal treatment planning of IMRT were screened satisfactory.Conclusion:CT-based simulation is the important step in IMRT and it's application correctly and rationally is the key to achieve the goal of IMRT. |
