An interactive data preparation procedure for three-dimensional interstitial and intracavitary dose calculation programs.
A computer system has been developed to assist in preparing data for interstitial and intracavitary calculations. This approach used graphic and interactive techniques, and removes all the format problems which led to errors in data preparation. The program reconstructs the implant and rotates it about X, Y and Z axes to allow close examination of the positions of the radiation sources. The site of the dose calculation can be selected by positioning a frame representing the calculation plane in the reconstructed implant. The output of the program is the three-dimensional data of the source and plane co-ordinates, together with the co-ordinates to define the area on the plane where the calculation is to be performed.
