Abstract
A method for creating a volumetric data set representing a three-dimensional distribution, such as a dose distribution produced by a radiosurgery system uses a plurality of stacked sensors (12) to obtain two-dimensional cross sectional images of the distribution. The images are optically scanned in a scanner (20) to obtain digitized two-dimensional images which can be processed by software in a computer (22). Each of the sensors (12), which may be, for example, a sheet of X-ray sensitive film, is marked with a visible fiducial mark (17). The software locates images of the fiducial marks (17) in the digitized images. The locations of the fiducial marks (17) indicate the proper orientation and sequence of each image. The software populates a volumetric data structure with data from the scanned images. Interpolation may be used to increase the resolution of the data structure. The system is not susceptible to errors which might be caused by images of the sensors being inverted or mis-aligned before or during scanning.
