ABSTRACT
Objective To analyze the stability and accuracy of the equipment for three-dimensional ultrasound-based image-guided radiation therapy (3DUS-IGRT) in daily practice, and to provide a basis for clinical application of radiotherapy for soft tissue tumors.Methods A specific calibration phantom was used for continuous calibration and quality control of the 3DUS-IGRT equipment in a year.The method for daily quality control of ultrasound-guided equipment was explored, and its stability and accuracy were monitored.Results The phantom position errors in both Sim and Guide stations of the 3DUS-IGRT equipment were within 1 mm.Conclusions The 3DUS-IGRT equipment has a stable performance with the support of a complete set of stringent and accurate calibration and quality control, which provides a new image-guided method for precise radiotherapy for soft tissue tumors.
