gantry

noun

Etymology: From earlier gauntree, possibly from dialectal gaun (“gallon”) + tree, perhaps as a reinterpretation of Middle English *gaunter, from Old Northern French gantier, from Late Latin cantarium, from Latin canterius (“trellis, sort of frame”).

1. A framework of steel bars resting on side supports to bridge over or around something.
2. A supporting framework for a barrel.
3. A gantry crane or gantry scaffold.
4. A faregate or turnstile controlling the entry and exit of people at a location.
5. A cylindrical scanner assembly in the bore of which the response of bodies or tissues to some specific exposure can be detected for 3D imaging.

   “In the tomographic images of the 30-day-old cheeses, the gantry had to be removed with image processing techniques: first, the binarised image (grey level larger than 10⁴) was eroded with a disk of three pixels.”
