Outlining
Organs must be outlined or they will be ignored
Planner may notice, computer will not!
Salivary glands, oesophageal sphincters,
cochlea, mandible
The whole organ of interest must be outlined
Easy not to outline whole lung – conservative, but
not ideal
Dangerous to ‘over outline’
Easy to ‘over outline’ rectum – under-estimate dose
