A Phantom Study of the Geometric Accuracy of Computed Tomographic and Magnetic Resonance Imaging Stereotactic Localization with the Leksell Stereotactic System

Abstract

The accuracy of target localization for most intracranial lesions during stereotactic radiosurgery can be achieved within the size of a voxel, especially by using the Siemens MRI scanner at current specifications and with a new software patch. However, caution is warranted when imaging peripheral lesions, where the distortion is greatest.
