Video-oculography is a very quantitative method to investigate ocular motor performance as well as motor learning. Here, we describe how to measure video-oculography in mice. Applying this technique on normal, pharmacologically-treated or genetically modified mice is a powerful research tool to explore the underlying physiology of motor behaviors.

Dual fluoroscopy accurately captures in vivo dynamic motion of human joints, which can be visualized relative to reconstructed anatomy (e.g., arthrokinematics). Herein, a detailed protocol to quantify hip arthrokinematics during weight-bearing activities of daily living is presented, including the integration of dual fluoroscopy with traditional skin marker motion capture.

The complete construction of a custom, real-time confocal scanning imaging system is described. This system, which can be readily used for video-rate microscopy and microendoscopy, allows for an array of imaging geometries and applications not accessible using standard commercial confocal systems, at a fraction of the cost.
FAQs
The X-ray source generates either a continuous or pulsed beam, while a digital detector captures sequential images. Reviewing these images as a time series reveals changes in anatomical position and the passage of radiopaque contrast, rather than presenting only a fixed snapshot. This temporal information permits assessment of function alongside structural appearance.
Radiopaque contrast materials make the movement of selected contents visible against surrounding anatomy. During gastrointestinal or pharyngeal assessment, substances such as barium can be tracked as they pass through the region being examined. Their changing position helps clinicians evaluate transit and movement, supporting recognition of obstruction, abnormal motility, or swallowing-related problems.
Sequential imaging can expose problems that may not be apparent from anatomy alone. In medicine, video fluoroscopy can help identify aspiration, obstruction, abnormal motility, and structural problems by showing how tissues or contrast move over time. Combining these functional observations with anatomical findings gives clinicians information relevant to diagnosis and treatment planning.
For swallowing assessment, the examination follows radiopaque contrast as it moves through the pharynx. The recorded sequence allows clinicians to evaluate the movement associated with swallowing and identify aspiration or other abnormal passage patterns. This functional information can complement anatomical observations and help inform subsequent diagnosis and treatment decisions.
In gastrointestinal evaluation, the technique can follow contrast through the gastrointestinal tract to assess passage and motility. In orthopedic motion studies, recording anatomical movement helps clinicians examine function during motion rather than relying only on static structure. These applications extend the method beyond swallowing assessment and support evaluation of different movement-related clinical problems.
During image-guided procedures, sequential X-ray images provide ongoing visualization of relevant anatomical structures and the movement of radiopaque material when used. This dynamic view can support procedural guidance while also showing functional or structural findings. Its value comes from linking the location of anatomy with changes occurring during the procedure, rather than using a single image alone.
