Basic Treatment Planning

Plan evaluation

• Most common method is to visually assess a plan in terms of PTV coverage, dose uniformity and check the tolerance of normal tissue. i.e. analyse your distribution in 3D

• Main plan evaluation tools: 

Visual assessment of isodose distribution in 3D (axial, coronal and saggital views)  Cumulative DVH for volumetric analysis  Summary statistics for minimum, maximum and mean doses
