X-Ray Tube: Focal Spot Size

The focusing cup is a negatively charged component designed to narrow the ______ cloud.

The region of the anode target where electrons interact to produce x-rays is known as the ______ spot.

For imaging small body parts with better spatial resolution, a ______ focal spot is preferred.

Using a small focal spot comes with the limitation of not permitting the use of higher ______.

A large focal spot is utilized to tolerate high ______ loading, which permits the capability to image larger body parts.

[Blank] spot blooming, which degrades image quality, is more likely to occur when mA is increased.

When operating at 400 mA or higher, only the ______ filament is typically allowed for x-ray production.

The circular path impacted by the electron beam on a rotating anode is referred to as the focal ______.

The ______ point is the specific area of the focal track that the electron stream impacts at any given moment.

The physical area of the focal track that is exposed to electrons from the tube current is known as the ______ focal spot.

According to the line focus principle, a steeper anode angle results in a smaller ______ focal spot size.

The length of the ______ and the anode angle are the 2 factors that directly determine the size of the actual focal spot.

The ______ focus principle states that by angling the anode target, a large actual focal spot can project a smaller effective focal spot.

The area projected onto the patient and image receptor is known as the ______ focal spot.

The ______ focal spot is the area of the focal spot that is projected out of the tube and towards the object radiographed.

The size and angle of the ______ focal spot determines the size of the effective focal spot.

A higher anode angle results in a small actual focal spot size but a ______ effective focal spot size.

For heavy tube loading cases, it is better to utilized the ______ focal spot over the alternative.

When electrons hit a larger than targeted area and cause degradation to the image it is called focal spot ______.

The ______ is designed to house the filament in the x-ray tube.
