Frameless stereotaxy of the brain.
Today's neurosurgical journals are replete with advertisements for systems designed to provide image guidance during surgery. These so-called "frameless" stereotactic systems provide the surgeon with navigational information, relating the location of instruments in the operative field to preoperative imaging data. Such information minimizes invasiveness by more accurately selecting the best tra...
متن کاملMonocular Visual Patient Monitoring for Frameless Stereotaxy
In this paper, we propose a low cost, robust vision based system for monitoring patient movements during stereotactic radiotherapy: the Monocular Visual Patient Movement Monitoring (MVPM) System. The system consists of a light weight mouth bite with dual fiducial system used for position tracking. One set of fiducials consist of easy-to-detect checkerboard whose 3D position can be tracked using...
متن کاملFrameless stereotaxy for surgery of the epilepsies: preliminary experience. Technical note.
Frameless stereotactic techniques used in conjunction with three-dimensional images allow accurate planning and performance of a variety of neurosurgical procedures. The authors have used the frameless stereotactic Allegro Viewing Wand system to provide real-time correlation of the operating field and computerized images in 42 neurosurgical operations, including 31 epilepsy procedures. The syst...
متن کاملAn automatic registration method for frameless stereotaxy, image guided surgery, and enhanced reality visualization
There is a need for frameless guidance systems to help surgeons plan the exact location for incisions, to define the margins of tumors, and to precisely identify locations of neighboring critical structures. The authors have developed an automatic technique for registering clinical data, such as segmented magnetic resonance imaging (MRI) or computed tomography (CT) reconstructions, with any vie...
متن کاملComparison of laser surface scanning and fiducial marker-based registration in frameless stereotaxy. Technical note.
The authors compared the accuracy of laser surface scanning patient registration using the commercially available Fazer (Medtronic, Inc.) with the conventional registration procedure based on fiducial markers (FMs) in computer-assisted surgery. Four anatomical head specimens were prepared with 10 titanium microscrews placed at defined locations and scanned with a 16-slice spiral computed tomogr...
