Simultaneously with the video recording, the EEG records brain activity. Both video and EEG information allows physicians to pinpoint the type of seizure that is occurring and precisely locate the source. On the one hand it is necessary to keep the patient as close as possible in the focus of the video to see also e.g. small muscle twitches, on the other hand the patient should also have the freedom to move around in his or her room.
For this purpose today’s video EEG systems use pan/tilt/zoom-cameras. They are manually controlled by medical staff who are usually in charge of continuously controlling the camera to keep the patient in focus, and at the same time to observe EEG activity for diagnosis. However, manual camera control and video monitoring over a longer period of time requires a lot of attention and direct camera control access which is sometimes hard to fulfill by all tasks need to be covered by the medical staff.
To overcome this daily challenge, NIHON KOHDEN and the Fraunhofer IOSB have developed an innovative automated patient tracking system, which consists of a two-camera-setup connected to the new Patient-Tracking-Software for video processing and camera control.
A static wide angle camera provides an overview of the entire monitoring room, while a pan/tilt/zoom-camera is used for active high resolution patient observation.
But the core component of the system is the new Patient-Tracking-Software, with integrated real-time video analytics for patient tracking and camera control. Highly efficient and robust visual marker detectors combined with color object trackers allow for 3D object localization in real-time and for a fully automated camera control.
The Patient Tracking System will be presented at the Medica 2013 in Düsseldorf, Germany, at the NIHON KOHDEN booth in Hall 09 / D15.

About Fraunhofer IOSB
Fraunhofer IOSB is carrying out research and development of multi-sensory systems, which help people perceive and interact with their environment. Hereby, Fraunhofer IOSB is active in a wide range of scientific categories like video analytics for security and safety applications, industrial inspection system, machine vision of automation and automotive.
The three core competencies optronics, system technology and image exploitation make up our unparalleled profile. Optronics originates from the combination of optics and electronics. It bridges the area between electromagnetic radiation as well as electric and electronic signals.
Image exploitation covers the preparation, real-time processing, automatic and interactive acquisition of information from images and videos. Image exploitation comprises preparation, real-time processing, automatic and interactive information acquisition from images and videos.
System technology covers everything required for the analysis, understanding, modeling, development and management of complex systems.
Fourteen departments and one research group, which acts as a link to the Chair of Interactive Real-Time Systems of the Institute for Anthropomatics at the Faculty for Information Technology at the KIT, represent the centre of competence at the IOSB with its round about 600 employees.
