title: Localization in interstitial dosimetry utilizing the CT scanner.
abstract: A simple method utilizing CT scanners which were readily available is described in which alignment of the isodose curves can be made directly on the printout of the CT scan. This has obvious practical and theoretical advantages. In particular, the dose to vital structures, such as spinal cord and other critical viscera, can be well described.
