title: Localization of brain tumors with a simple scalp-mounted fiducial device. Technical note.
abstract: A method is described for marking the site of a tumor on the scalp based on information from computerized tomography (CT) scans. The technique employs a syrinx-shaped array of radiopaque catheters of varying length taped to the patient's scalp for visualization on the CT scan. Fiducial markings on the CT images allow the transfer of the tumor's location directly onto the scalp. The device can be placed anywhere on the scalp, including in a parasagittal position.
