Dose Verification in Intensity Modulation Radiation Therapy: A Fractal Dimension Characteristics Study

Figure 6

The relationship between length and scale (tiles size) can be implemented by transforming an image into a mosaic and regarding the elements (individual tiles) of the mosaic as being square tiles laid around the boundary. The mosaic transformation can be used to set up a procedure for evaluating the fractal structure of the boundary by a technique known as mosaic amalgamation. The perimeter estimated in (a) is smaller than (b) due to the larger scale (the length of the mosaic tile) used in (a).
