Fiducial markers are used in a wide range of medical imaging applications. Images of the same subject produced with two different imaging systems may be correlated by placing a fiducial marker in the area imaged by both systems. In this case, a marker which is visible in the images produced by both imaging modalities must be used.
In medical electrophysiological monitoring, artifacts are anomalous (interfering) signals that originate from some source other than the electrophysiological structure being studied.

Assessment of the aesthetics is mostly subjective and any orthodontic index which has an aesthetic component can reduce the objectivity of the index in determining the need for treatment and theoretically not suitable for assessing orthodontic treatment need in a research setting or resource allocation.
A dental impression of a section of teeth which records the bite, which can be used to replicate how the teeth bite together. Bite registration is a technique carried out in dental procedures, where an impression is taken of the teeth while biting together, to capture the way they meet together in a bite.
The accurate rephotographer usually determines several facts before taking a new image. [19] An important starting point is the choice of the older image. To show continuity between the two images, rephotographers usually include in the frame a building or other object which is present in the modern view.
