Figure 2From: Heterogeneity of microsphere distribution in resected liver and tumour tissue following selective intrahepatic radiotherapyHistogram reflecting the distribution of spheres observed by microscopy in normal liver parenchyma of Pt 2. Six biopsies from Pt 2, with a total volume of 36 mm3, divided into 60 slices were investigated. Bars show the number of clusters found with each size, i.e. spheres per cluster. Fifty-three percent of all 793 spheres found were located within any of the larger clusters (8 to 59 spheres/cluster).Back to article page
