title: Intraoperative angiography in cerebral aneurysm and AV-malformation.
abstract: The device is constructed for intra-operative angiographic studies. The main features of the unit are: semi-automatic positioning of the tube into preset coordinates, TV camera serving as receptor, reproduction of the videosignal with twice the number of lines compared with that used normally, retrieval technique permitting one to study the flow of the contrast medium in slow motion at the required speed. Further advantages: Intra-operative control of the correct operative technique. No need for postoperative anaesthesia and cerebral angiography.
