  Purpose: Objective of this present study is to assess the correlation factor kDVH (Dose Volume Histogram) for the Verisoft PTW software for different clinical sites. Materials and methods: Utilizing a simple dose reconstruction method in OCTAVIUS® 4D phantom, the measured dose in the array is 3D reconstructed. The DVH derived from Treatment Planning System (TPS) is compared with the DVH generated in Verisoft software from the measurement. To match these obtained histograms, user defined correction factor available in Verisoft application. The present study is intended to obtain a constant value that could be helpful in the comparison between the TPS DVH with the Verisoft generated DVH for all the clinical manifestations. In the present study, 9 cases, 10 cases, 11 cases and 10 cases of Oesophagus, Brain, Rectum and Head & Neck respectively total 40 cases have been taken for th.. Read More»
