Children who have complex communication needs can benefit from the use of a speech-generating device (SGD). Cognitive skills were identified as having an impact on the ability to navigate between levels of SGDs. This protocol describes the steps needed for Speech-language Pathologists to assess cognitive skills and navigational abilities.

Dynamic navigation systems (DNS) provide real-time visualization and guidance to the operator during endodontic access cavities preparation. The planning of the procedure requires three-dimensional imaging utilizing cone beam computed tomography and surface scans. After the export of the planning data to the DNS, access cavities can be prepared with minimal invasion.

FAQs
Medical imaging supplies the anatomical information used to create a reference for navigation. Spatial tracking follows the relevant positions in the physical environment, while image registration aligns that digital information with the patient. Working together, these components allow virtual anatomy, targets, or instrument paths to remain coordinated with the operative setting.
Real-time alignment keeps virtual content tied to the patient rather than treating the digital model as a separate reference. Registration provides the correspondence between anatomy shown in medical images and the physical operative field, while tracking supports continued spatial coordination. This matters because clinicians can interpret targets or planned paths in procedural context, supporting orientation and potentially precision.
Unlike a workflow that requires clinicians to repeatedly consult a separate monitor, AR navigation presents relevant virtual information within the view of the physical environment. This can preserve access to anatomical context, targets, or instrument paths while attention remains directed toward the patient and operative field. The arrangement may support procedural orientation without requiring continuous monitor viewing.
An AR navigation workflow begins with preoperative data, which can be linked to virtual anatomical models, target locations, or planned instrument paths. Spatial tracking then relates those digital elements to the patient and operative field, and image registration establishes their alignment. During the procedure, the system presents this information in the clinician’s view for orientation and guidance.
AR navigation has three clearly described medical uses: supporting surgery, assisting image-guided interventions, and supporting clinical training. In operative and interventional settings, it links preoperative data with the field where care occurs. In education, the same connection can help learners interpret anatomy and procedural relationships, making the technology relevant both to patient-care workflows and preparation for them.
Potential benefits extend beyond displaying anatomy. By connecting digital imaging with the patient and procedure, the approach may improve procedural orientation and precision while giving clinicians contextual information in the operative field. In training, it can support understanding of anatomy and planned actions. These roles position AR navigation as part of the broader integration of digital imaging into patient care.
