Abstract
The integration of 3D imaging for gynecological brachytherapy treatment planning allows the use of dose and volume parameters to describe the dose distribution related to target volumes and normal tissue. The dose and volume specifications introduced by the GEC ESTRO serve as recommendations for recording and reporting, and can also be used for prospective treatment planning. However, these dose volume histogram parameters do not fully describe the spatial dose distribution. By increasing the target conformity and dose shaping, accuracy in the 3D reconstruction of applicator geometry and its relation to the anatomy is paramount. This form of brachytherapy can be performed as real image-guided radiotherapy, with adaptive treatment planning for each application or fraction. Uncertainties and variations must be studied and taken into account to arrive at high-quality treatments with increased target dose and lower dose to the organs at risks.
