THE APPLICATION OF FULL SCALE 3D ANTHROPOMETRIC DIGITAL MODEL SYSTEM IN RADIOTHERAPY POSITIONING AND VERIFICATION

Abstract

The full scale 3D Anthropometric Digital Model system is a technique combining digital imaging, three-dimensional (3D) image processing and reverse engineering to produce a full-scale solid Anthropometric Digital Model. This paper describes the Anthropometric Digital Model being made and used in radiation treatment. By using computed tomography and optical scanning, the data required for the Anthropometric Digital Model is collected. Through surface reconstruction, a model of the patient skull is made, after which rapid prototyping and rapid tooling is applied to acquire a 1:1 solid model. Thus, without the patient needing to be present, the medical physicist or dosimetrist will be able to design a treatment plan tailored to the patient and to simulate all kinds of situations on the simulator and the linear accelerator for positioning and verification. We expect that the application of Anthropometric Digital Model can reduce the time spent on pretreatment procedures in radiotherapy and enhance the quality of health care for cancer patients.
