Defining the radiation target on a daily basis

Area of Science:

• Radiation Oncology
• Medical Imaging

Background:

• Accurate target volume delineation is essential for effective radiotherapy.
• Daily variations in target position necessitate re-evaluation of static imaging protocols.

Purpose of the Study:

• To re-evaluate the procedure for defining the target volume using a single computed tomography scan.
• To highlight the benefits of newer image-guided radiotherapy technologies.

Main Methods:

• Review of traditional radiotherapy target volume delineation methods.
• Evaluation of advancements in image-guided radiotherapy (IGRT).

Main Results:

• Traditional methods based on single computed tomography scans may not account for daily variations.
• Image-guided radiotherapy enables on-line, daily target volume definition.

Conclusions:

• On-line daily target volume definition using image-guided radiotherapy enhances treatment precision.
• Modern radiotherapy planning should incorporate adaptive strategies based on daily imaging.
