The source of electron in the xray assembly is

• Anode

• Filament

• Cathode

• Focusing cup

The tungsten target is located on the

• Cathode

• Focusing cup

• Anode

• Aluminum foil

The component of xray machine that helps to remove weak photons is called

• Lead foil

• Aluminum filter

• Photon remover

• Evacuator

Tube current for computed tomography ranges from

• 50-72kvp

• 90-120kvp

• 50-90kvp

• 100-200kvp

Silver halide grains are composed primarily of

• Silver metal

• Silver floride

• Silver bromide

• Silver ion

Films that are intended to be exposed x-rays are called

• Intensifying films

• Direct exposure films

• X-ray films

• Screen films

The function of the gelatinous matrix during film processing

• Hold the halide crystals

• Expose the film

• Absorb processing solution so they can reach the film

• Increase the film sensitivity to radiation

The base of thr dental film is made of

• Polyethylene polyester terephthalate

• Polyester polyethylene terephthalate

• Polyester polyethylene di-terephthalate

The following are advantages of direct exposure film over film screen except

• High resolution images

• Low radiation exposure

• Good for diagnosing incipient caries

• Sensitive to x-ray
