Spatial extent of magnetic resonance imaging acquisition; larger field of view shows more anatomy but lower resolution
Expansion
Field of View
Purpose
Balance between coverage and resolution
Clinical Context
Field of view determines acquisition area. Smaller field of view increases spatial resolution but reduces anatomical coverage. Typical body field of view 240 to 380 millimetres.
