Monocular Visual Patient Monitoring for Frameless Stereotaxy
نویسندگان
چکیده
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 a pre-calibrated off-the-shelf camera and a set of radio-opaque rods suitable for X-ray imaging. We describe the associated workflow steps for using the system during planning and treatment phases. Also we report experimental results for tracking accuracy using a in-house phantom.

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 کاملFrameless 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 کاملStudy on the clinical application of pulsed DC magnetic technology for tracking of intraoperative head motion during frameless stereotaxy
BACKGROUND Tracking of post-registration head motion is one of the major problems in frameless stereotaxy. Various attempts in detecting and compensating for this phenomenon rely on a fixed reference device rigidly attached to the patient's head. However, most of such reference tools are either based on an invasive fixation technique or have physical limitations which allow mobility of the head...
