About

Field of View (FOV) is dictated by the sensor size and the setting on the machine. The larger the CBCT sensor the larger the final FOV will be and the higher the cost of the machine. Choosing the right sensor size or FOV is crucial and should be at the top of your list. FOVs in CBCT can be divided into small, medium, large and extended fields of views.

Field Of View

Small Field of View

Usually 5cm x 5cm (length by height) or less. Applications are typically for: Endodonticsas, as a small FOV is quite sufficient as the area of interest is a single tooth or few teeth.

Medium Field Of View

Usually, 5cm x 7cm, 8cm x 8 cm, 10cm x 5cm, 12 cm x 8 cm and 10cm x 10 cm. There machines can collimate the x-ray beam to a smaller FOV so if you want a single tooth scan, you do not need to scan the entire maxillo-mandibular area. Medium FOV can capture both jaws at a time excluding the temporomandibular joint (TMJ).

Large Field Of View

Usually, 15cm x 15cm. This is preferred by Oral Surgeons. Ideal for viewing and evaluating pathology Surgical evaluation and planning Airway assessment for sleep apnea.

Extended Field Of View

Usually, 20cm x 20cm. Used mainly by Orthodontists as it captures areas outside the maxilla-mandibular region to include the Sella Turcica and base of the skull..
