Figure 1From: Biological in-vivo measurement of dose distribution in patients' lymphocytes by gamma-H2AX immunofluorescence staining: 3D conformal- vs. step-and-shoot IMRT of the prostate glandMerged DAPI and gamma-H2AX stains in human blood lymphocytes. Number of phosphorylated H2AX-foci corresponds with the dose. Different doses are shown: 0.02, 0.1, 1 Gy and the non irradiated sample. Irradiation was performed homogeneously in-vitro on a linear accelerator (Oncor, Siemens).Back to article page
