AbstractNavigation has become widely integrated into regular endoprosthetic procedures, but clinical use of navigation systems in orthopaedic trauma has only been implemented in a few indications. Navigation systems enable an accuracy of 1 mm or 1 degree. Navigation can achieve higher precision when it is combined with different imaging modalities, including preoperative computer tomography (CT), intraoperative CT, two-dimensional fluoroscopy, and, recently, intraoperative three-dimensional fluoroscopy. The precision of the navigation system can be influenced by the surgeon as well as by the camera system, type of reference marker, and the registration process. Recent developments in orthopedic trauma navigation allow for bilateral femoral anteversion measurements, noninvasive registration of an uninjured thigh, and intraoperative three-dimensional fluoroscopy-based pedicle screw placement. Although the use of navigation has provided initial positive results in trauma care, prospective clinical studies remain to be performed.

Electromagnetic tracking has great potential for assisting physicians in precision placement of instruments during minimally invasive interventions in the abdomen, since electromagnetic tracking is not limited by the line-of-sight restrictions of optical tracking. A new generation of electromagnetic tracking has recently become available, with sensors small enough to be included in the tips of instruments. To fully exploit the potential of this technology, our research group has been developing a computer aided, image-guided system that uses electromagnetic tracking for visualization of the internal anatomy during abdominal interventions. As registration is a critical component in developing an accurate image-guided system, we present three registration techniques: 1) enhanced paired-point registration (time-stamp match registration and dynamic registration); 2) orientation-based registration; and 3) needle shape-based registration. Respiration compensation is another important issue, particularly in the abdomen, where respiratory motion can make precise targeting difficult. To address this problem, we propose reference tracking and affine transformation methods. Finally, we present our prototype navigation system, which integrates the registration, segmentation, path-planning and navigation functions to provide realtime image guidance in the clinical environment. The methods presented here have been tested with a respiratory phantom specially designed by our group and in swine animal studies under approved protocols. Based on these tests, we conclude that our system can provide quick and accurate localization of tracked instruments in abdominal interventions, and that it offers a user friendly display for the physician.

“…The results of a measurement can be either accurate but not precise or precise but not accurate, neither or both. Precision is the degree of veracity while precision is the degree of reproducibility [9][10][11]. A result is called valid if it is both accurate and precise.…”

“…The reliability test of motion analysis system in the aspects of precision and repeatability was performed regarding the frame-to-frame repeatability of the measurement [12]. The landmark, distance between markers and angle studies investigated using Optotrak system and suggested about the reliability of motion analysis systems [9], [10], [13], [14].…”

Neck pain or cervical pain is most common in individuals who are all working in seated postures for prolonged period of time, example computer users. The pain caused by extreme postural positions including forward head postures and extension angle maintained in cervical. The use of cervical vertebra traction therapy has increased as a part of rehabilitation medicine. However, lack of usability standard in this traction therapy i.e., the exact instructions on how to choose the traction force and location are unclear. To fix this issue, first, the cervical spine traction system analysing the change of cervical spine depending on the traction location has been investigated. Motion analysis systems are widely used to measure the changes in the body part movement. However, the precision and repeatability of motion analysis systems are not much studied. In this paper, the precision and repeatability of a three-dimensional (3D) motion analysis system (i.e., NDI's Optotrak Certus (OC)) is evaluated with developed 3D robot for traction therapy as an application example. The 3D robot quantitated the accuracy and precision of the system regarding angle and distance. Angle and distance among markers showed good agreement between measurements, and comparable measures of precision reported. Experimental results demonstrate a measure of precision and repeatability for the movement of the patients on the cervical traction system; hence the repeatability was satisfactory.
