Computer assisted stereotactic neurosurgery

摘要

We present a software package for the manipulation of multimodality digital images for computer assisted stereotactic neurosurgery. Stereotactic neurosurgery uses imaging data to guide a surgical instrument to reach an intracerebral target through a small bore-hole in the skull. Besides the specific requirements for image acquisition, we discuss the different functions of the package: image transfer, geometric calibration of CT, MR and DSA, user interfacing and display modalities (multi-planar reslicing, angiographie projections). We finally demonstrate the improved functionality by reporting on some typical clinical cases for functional neursurgery and stereotactic biopsies.
