From: Novel high dose rate lip brachytherapy technique to improve dose homogeneity and reduce toxicity by customized mold

Figure 2

Comparison between the "sandwich" technique and "classic" interstitial only technique. Reconstructive image of the interstitial and mold catheters in relation to the lip and the mandible (A). Comparison of the DVH between the interstitial catheters only (B) and the CMS (C) techniques at the same level. Note the invagination of the dose to the mandible in the “classic” interstitial catheters technique. Coverage by the lip catheters (D,F) compared to the CMS (E,G) from two different angles. The DVH of the target in the interstitial catheters only (H) and the CMS (I) techniques. Note that the high dose regions without the mold are more than twice that as with the mold. DVH = Dose Volume Histogram CMS = Customized Mold Sandwich.
