Automatic Seed Reconstruction: Hough Transform

(a) A simple binary image containing lines. (b) The Hough transform of the image. (c) The Hough transform contrasted to display the underlying structure.

(a) Seed positions as determined by the described algorithm. (b) Theoretical seed coordinates. The seeds appear in the inferior to superior direction because the point dose approximation was used and the true orientation is not needed .

seed localization error ranged from 1-3 mm
