Paper Abstract

The major aim of conformal therapy is to engulf the tumor volume by a high radiation dose while minimizing the exposure of the surrounding healthy tissue. Visualization of the tumor volume, dose, and surrounding tissue is an important step in determining if the proposed treatment plan is optimal or even acceptable. This paper investigates the use of interactive volume visualization for the dose volume as well as the anatomical data. A commercially available volumetric processor capable of computing 10 million transformed and trilinearly interpolated points per second is used to generate multiplanar reformatted (MPR) and 3D displays of patient anatomy and radiation dose. The dose is treated as a volume data set in it's own right, which allows for the arbitrary selection of any isodose surface with interactive control of dose level and relative beam weights for multi beam treatment plans. A coarse-to-fine strategy is employed for all viewing modes. MPR views are generated at the rate of approximately 10 frames per second with 3D displays taking approximately 10 seconds per view. Clinically useful images, indicating the variation of radiation dose levels combined with 3D anatomy, can be generated interactively, allowing for the rapid evaluation of complex treatment plans.
