=== Other uses === Flatbed scanners have been used as [[Digital camera back|digital backs]] for [[Large format|large-format]] [[camera]]s to create high-resolution digital images of static subjects. A modified flatbed scanner has been used for documentation and quantification of [[Thin-layer chromatography|thin layer chromatograms]] detected by [[Quenching (fluorescence)|fluorescence quenching]] on [[silica gel]] layers containing an [[ultraviolet]] (UV) indicator.<ref>{{cite journal | last=Campbell | first=Alison | author2=Michael J.

Flatbed scanners may also be used to create artwork directly, in a practice known as [[scanography]]. In the biomedical research field, detection devices for [[DNA microarray]]s are also referred to as scanners. These scanners are high-resolution systems (up to 1 ΞΌm/pixel), similar to microscopes. Detection is performed using CCDs or photomultiplier tubes. In [[pathology]], scanners are used to capture glass slides with tissue from [[biopsy|biopsies]] and other kinds of sampling, allowing for various methods of [[digital pathology]] such as [[telepathology]] and the application of [[artificial intelligence]] for interpretation.
