[14] Similar to our study results, Grade 3 or greater wound complications can probably be decreased using meticulous treatment planning to decrease the tissue volume encompassed by the 150%
isodose line.
The prescribed
isodose line was 80 [+ or -] 3.1% (72%-90%), the mean CI was 1.3 [+ or -] 0.1 (1.1-1.5), the mean nCI was 1.4 [+ or -] 0.1 (1.1-1.5), the mean HI was 1.3 [+ or -] 0 (1.1-1.4), and the mean coverage (%) was 96.4 [+ or -] 1.5% (91.5%-99.1%).
[11] 57 patients with T1- 45Gy/3# prescribed to Analysis of phase 2 2N0M0 inoperable 67%
isodose line multi-centre trial NSCLC Male n=26; encompassing PTV.
(c) Dose distribution: the
isodose lines are 100% (pink), 90% (yellow), and 50% (sky blue), respectively.
Here in this image the 90%
isodose line, which is the line that is the dose prescription line, straddles the skin surface, a good plan.
[Figure 2] and [Figure 3] show that, when stenting of the portal vein was combined with implantation of a single [sup]125I seed strand and activity of the [sup]125I seed was 0.3–0.8 mCi, reference
isodose curves/surfaces could not completely “wrap” the target volume around the stent.
The parotid glands shrink more than the submandibular glands, increasing the risk of parotid insight into nodal target
isodose [9, 10].
One month after the hemorrhage, she underwent gamma knife radiosurgery with a prescription dose of 24 Gy with a 40%
isodose line and treatment volume of 1.2 mL.
The prescribed dose was normalized to 100% at the isocenter and PTV was covered by 95%
isodose surface (ICRU Report 50).
The
isodose curves in % of the gamma dose rate distribution using MATLAB in the GB-127 source are presented in Figure 5.
Isodose distributions in three planes (axial, sagittal, and coronal) and dose-volume histograms of PTV and OARs were used to guide plans optimization.
Fraction schemes with different BED are reported to influence the LC [13,15]; (3) inhomogeneous dose prescription was used in these studies, such as 50%
isodose covering 95% PTV, 100%
isodose covering 95% PTV, and 60%
isodose covering 100% PTV.
