Fig. 3From: Three-dimensional verification of 125I seed stability after permanent implantation in the parotid gland and periparotid regionSeed Stability Index. All stability studies were based on CT data from four fixed points in time: 1 = day 1 post-implantation; 2 = 2 months post-implantation; 3 = 6 months post-implantation; and 4 = 12 months post-implantation. a Minimum bounding box volume per patient over time; b average minimum bounding box volume over time; c average inter-seed distance (d) per patient over time; d average inter-seed distance (d) over time. *Error Bars: +/− 2 standard error (SE)Back to article page
