Retraining abnormal movement patterns following injury or disease is a key component of physical rehabilitation. Recent advances in technology have permitted accurate assessment of movement during a variety of tasks, with near instantaneous quantification of results. This provides new opportunities for modification of faulty movement patterns in real time.
FAQs
Image-to-patient registration links anatomical information from preoperative or live imaging to the patient’s actual position. This relationship allows the system to display an instrument relative to the relevant anatomy rather than showing imaging information in isolation. Accurate registration is therefore central to following a planned trajectory and maintaining meaningful spatial guidance during image-guided intervention.
Imaging supplies the anatomical information used for planning and guidance, while tracking sensors provide the position of an instrument, person, or device. Software combines these inputs so clinicians can view instrument location in relation to anatomy. Together, the components connect the planned path with immediate spatial feedback, supporting more precise instrument handling.
Movement can change the relationship between the instrument, the patient, and the planned path. Real-time navigation addresses this by updating position and recalculating guidance as conditions change. Continuous updates help clinicians maintain awareness of the instrument’s location, follow the intended trajectory, and respond to changing spatial relationships during a procedure.
A fixed preoperative plan provides anatomical information and an intended trajectory before intervention, whereas real-time navigation adds ongoing spatial feedback during movement. By combining preoperative or live imaging with tracking and software updates, the system can relate current instrument position to the plan. This supports adjustments during the procedure instead of relying solely on an initial image or path.
A typical workflow begins with preoperative or live imaging, followed by registration of the images to the patient. Tracking sensors then identify the instrument’s position, and software displays that position relative to anatomy and the planned trajectory. As movement occurs, the system updates guidance, giving the clinician continuous spatial information for procedural decisions.
The technology supports image-guided surgery, catheter placement, biopsy, and other minimally invasive procedures. In these settings, clinicians can use displayed instrument location and anatomical information to follow planned trajectories and help avoid critical structures. Its value is greatest when accurate spatial relationships matter for directing an instrument through or toward a specific anatomical target.
By linking patient-specific anatomical information with immediate feedback about instrument position, the approach helps clinicians adapt guidance to the individual procedure. This connection can support more precise trajectory following and more consistent decision-making. In that context, real-time navigation contributes to personalized interventions by applying the patient’s anatomical information directly to procedural guidance.
