A review of validated techniques and tools for tumor intensity-modulated radiation therapy

Abstract

Intensity-modulated radiation therapy (IMRT) is an advanced tumor treatment technique that enables precise three-dimensional dose distribution. However, factors such as field design, data algorithms, and machine errors may lead to deviations between the actual dose and the planned dose, potentially resulting in irradiation errors. Common dose verification methods include point dose verification, two-dimensional dose verification, and three-dimensional dose verification. This paper reviews various verification methods and focuses on the errors and limitations of each method to improve the safety and effectiveness of IMRT treatment.
