Abstract/OtherAbstract:
A computer language is presented that can be used to generate image files, as if the images are created with a CT or a MR scanner. The language defines objects in the "scanner's" coordinate system, as sets of quadratic inequalities. Each of these objects, e.g., an ellipsoid or a half-plane or a cylinder, has its own density. Objects can be superimposed and collections of objects are allowed to translate and rotate. The language allows for a concise way of describing complex objects with precisely defined geometries and densities. An implementation of the language can be used for testing, developing, and analyzing diagnostic software, treatment planning systems, etc. A software module that is based on the language can be made available. The utility of the module for acceptance testing of radiation therapy treatment planning systems is described.
