Contour Changes In Head And Neck Cancer
|
Here are some underlying questions that bear thinking about before discussing the merits of the additional technology:
- Can we detect a contour change easily?
- What is the oncological (not dosimetric) importance of a contour change?
- Is on-line dose calculation likely to be dosimetrically accurate?
- Is your current voluming/contouring accurate? to what level - 0-1mm, 1-2mm, 2-3mm, 3-4mm, 4-5mm?
- Is automated voluming/contouring accurate?
- How good does your own voluming/contouring have to be for you to adequately critique the automated output?
- Is an additional imaging modality needed for accurate detection of contour changes during radiotherapy?
