DVH Analyzer: design and algorithm to reveal DVH bands for quantitative analysis of robust radiotherapy treatment plans

Autor: Vivek Kumar, Arun S Oinam, Atul Tyagi, Deepak Thaper, Rose Kamal, Gaganpreet Singh

Publikováno v: Health and Technology. 11:981-994

Background: Commercial treatment planning system (TPS) does not have any tool to provide the quantitative analysis of DVH bands (corresponding to each delineated structure) in a radiotherapy treatment plan (RTP). The proposed study reveals the design

Degree of reduction in normal liver complication probability from free-breathing to breath-hold liver SBRT: a dose-escalation strategy using radiation dose-volume effect

Autor: Deepak Thaper, Hanuman P Yadav, Deepti Sharma, Rose Kamal, Gaganpreet Singh, Arun S. Oinam, Vivek Kumar

Publikováno v: Biomedical physicsengineering express. 8(1)

Introduction. This study aimed to analyze the degree of reduction in normal liver complication probability (NTCP) from free-breathing (FB) to breath-hold (BH) liver SBRT. The effect of the radiation dose-volume on the mean liver dose (MLD) was also a

Impact of dose heterogeneity in target on TCP and NTCP for various radiobiological models in liver SBRT: different isodose prescription strategy

Autor: Deepak Thaper, Gaganpreet Singh, Rose Kamal, Rishabh Kumar, Vivek Kumar, H. P. Yadav, Arun S Oinam

Publikováno v: Biomedical physicsengineering express. 7(1)

Introduction: The impact of dose heterogeneity within the tumor on TCP and NTCP was studied using various radiobiological models. The effect of the degree of heterogeneity index (HI) on TCP was also analyzed. Materials and Methods: Thirty-seven pre-t
