Exam 3: Image Formation and Radiographic Quality

Beam attenuation is increased with a higher-energy x-ray beam.

Radiographic misrepresentation of the size or shape of the anatomic structure being imaged is:

The smallest object that can be detected in an image is the:

The interaction between x-ray photons and tissue that results in production of a secondary x-ray photon is the:

A fewer amount of photons reaching the IR has what effect on the formation of the image?

The highest quality radiographic image has no unsharpness.

The photoelectric effect involves the removal (ejection)of an electron.This process of removing an electron from an atom is known as:

Magnification always results in reduced recorded detail.

Subject contrast is dependent on the:

Interactions of high-energy x-rays (energies beyond the diagnostic range)with tissue include:

The x-ray photon that is scattered as a result of the Compton effect cannot:

If scattered photons are absorbed within the anatomic tissue,they:

Recorded detail is the term commonly used in digital imaging to describe the accuracy of the structural lines that make up the image.

An image that has excessive brightness or insufficient density is considered:

The overall blackness on the processed film image is:

At higher kilovoltage,_____ photon interactions occur,resulting in _____ transmission.

An increase in the amount of unsharpness recorded on the image has what effect on the visibility of anatomic structures?

The device that receives the radiation leaving the patient is the:

The primary factor that affects film-screen density is the quantity of radiation reaching the IR.

With radiographic imaging,anatomic tissues,such as bone,that absorb most of the radiation result in that area of the image being:
