Description
Motion management in Radiation Therapy (MMRT) is important for tumors that move. Intra fraction motion is an issue that needs to be addressed during simulation, planning and treatment delivery. During simulation, a surrogate device is used that correlates the position of the tumor to the respiratory cycle to generate a 4DCT. Various methodologies in 4DCT, namely phase and amplitude based binning and generation of Maximum intensity projections (MIP), Minimum intensity projections (minIP), or Average Intensity projections (AI) will be reviewed. Depending on the method chosen for treatment delivery, the target delineation can be restricted to individual phases like exhale, inhale or part or entire tumor motion envelope (Internal Tumor Volume (ITV). Average or Helical CT can be used for treatment planning. Treatment Delivery during tumor motion causes blurring of the dose distribution
