8 mCi, reference isodose
curves/surfaces could not completely “wrap” the target volume around the stent.
Dose distribution scheme of isodose
curves was observed to compare both applicators.
The radiation dose prescribed was between 70% and 80% of the isodose
The median marginal dose to the meningioma was 14Gy (range 12-30), maximum dose to the meningioma was 28Gy (range 24-60), and the median 50% isodose
line was 50% (range 50-80).

This is called the isodose
concept of tumoricidal radiotherapy).
2] Doses of 14 to 15 Gy to the 90% isodose
curve were given over a period of 10 fractions.
Users optimize treatment plans by making adjustments in the position of the radiation sources while observing the computed dose distribution, which is usually displayed as an isodose
contour map superimposed over a cross-sectional view of the patient's anatomy.
We can visualize the isodose
lines simultaneously as we trace them and the dynamic shaping makes dose planning much simpler.
The conformity of the plans was measured using the CI, calculated as the ratio between the volume of the reference isodose
(V[sub]95%) and the PTV volume (V[sub]PTV, V[sub]95%/V[sub]PTV).
A dose of 22 Gy was prescribed to the 56% isodose
and delivered in three fractions on the nidus at C1 level, and 18 Gy was prescribed to the 60% isodose
and delivered in two fractions on the nidus at C2 level.
