Accuracy of stereotaxic localisation using MRI and CT.
The accuracy of stereotaxic coordinates determined using the Leksell apparatus with CT and MRI was investigated using an Agar filled head phantom. Both imaging techniques were found to produce an accuracy of better than 2 mm with the exception of the Z coordinate as measured by CT (2.3 mm). This latter error is greater because of the 3 mm slice width used. Direct coronal views were used to dete...
متن کاملSimplified CT-guided stereotaxic biopsy.
A stereotaxic frame worn during computed tomographic (CT) scanning of the head produces landmarks in each section that are used to relate section coordinates to frame coordinates. A small, commercially available, programmable calculator is used to interrelate frame and CT section geometry. The system can be used with any CT scanner that can specify (x,y) coordinates of a pixel, obviating the ne...
متن کاملCT-guided stereotaxis using a modified conventional stereotaxic frame.
Computed tomographic (CT)-guided stereotaxic procedure have become established in a few major centers but a single optimal system has not yet emerged. At Duke University Medical Center, availability of a stereotaxic frame with design features that lend themselves to CT adaptation made modification of this unit, rather than construction of a new dedicated frame, cost-effective. As other centers ...

15 صفحه اولCombined use of stereotaxic CT and angiography for brain biopsies and stereotaxic irradiation.
A Riechert Mundinger stereotaxic device was modified to enable artifact-free computed tomographic (CT) scanning with the stereotaxic frame attached to the patient's head. A localization system was developed allowing determination of the XYZ coordinates of the target point directly from the CT cut. Angiography was performed intraoperatively with the stereotaxic frame attached. Coronal and sagitt...
