Utilization of the computed tomography scanner in interstitial dosimetry.
A method is described by which the isodose distribution of interstitial implants can be superimposed on the image of a computed tomography (CT) scan. This technique decreases the uncertainty about the delivered dose, and thus enhances clinical judgment. CT scans of implants in the head and neck area, cervix, vagina, rectum, and urethra are regularly obtained.
