Abstract
We have developed a Macintosh II based workstation for stereotaxis neurosurgery. Computed Tomography (CT) and Magnetic Resonance Images (MRI) are displayed in the NIH Image environment, customized to include stereotaxic and image manipulation utilities. To obtain the soft tissue detail of MRI images along with the bone definition and coordinate system of CT images, scans from the same patient are registered globally. A transformation is calculated to align the planes of the MRI images along CT planes, and this is then used to extract a MRI slice to correspond to a CT slice containing the target site. The extracted slice is warped, to correct for local misregistration, using corresponding landmarks in this and the CT image. The composite image, generated by overlaying the two, is used to calculate the Brown- Roberts-Wells stereotaxis frame angle settings needed to access the target. Path planning using reformatted CT slices is available as another option. Experimental validation using patient data has been done. This workstation has all the capabilities of a conventional CT workstation in addition to these stereotaxis routines.
