Abstract

A method of intracavitary treatment planning and dosimetry analysis which uses multi-planar reconstructed computerized tomography (CT) images is presented. The aim of the method is to improve ability to precisely locate clinical reference points, to fully define pertinent anatomic structures and to provide dose distributions and their relationship to these structures in multiple planes. Our approach is based on interactive treatment planning and point dose display on sagittal and coronal reconstructed CT images as well as the usual transaxial image. The advantages of clinical evaluation of isodoses directly on multi-planar CT images are assessed. These include precise anatomic and dose relationships between the cervix and paracervical structures, the bladder, rectum and pelvic node-bearing sites. Problems of image magnification, blurred images and inadequate resolution attendant to orthogonal radiographs, which are the basis of current techniques, are minimal. Analysis and results of the method and a comparison with the technique of orthogonal radiographs are presented for a demonstration case.
