ENDO-NEURO-SONOGRAPHY - PRINCIPLES AND 3-D TECHNIQUE

To evaluate the usefulness of transendoscopic sonography we studied tw o new sono probes 6 F in diameter in 17 fresh specimens. We saw precis e imaging of well-known anatomical structures and also gained an addit ional dimension in endoscopy, as the sono adds to the endo-view a tran sverse scan like a mini-CT at the tip of the probe. We also experience d the navigation characteristic nf this imaging technique, both in rea l time and on line. Some 3-D reconstructions of the ventricular system were examined. The equipment has been used in clinical practice and m ust now be adapted for neurosurgery.
