Exam 3: Image Formation and Radiographic Quality

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

X-ray absorption is more likely in tissues with a lower atomic number.

_____ is the loss of some of the energy from the x-ray beam as it passes through the tissue being imaged.

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

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

When the x-ray photon travels completely through the part, that activity is called:

Magnification always results in reduced recorded detail.

When the x-ray photon strikes an atom within the tissue being imaged and loses all of its energy to an inner shell electron of that atom, the photon is said to have been _____ and undergone the _____.

Approximately 20% of the primary x-ray beam actually reaches the image receptor.

An unwanted image on a radiograph is:

A film image with a large number of similar densities:

The Compton interaction can occur within all diagnostic x-ray energies.

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

Muscle tissue absorbs more radiation than fat tissue because muscle tissue has a:

Due to ________________________, repeats are often needed with film-screen imaging, because the image is too dark or light.

The brightness/density and contrast of film-screen and digital manifest images can be adjusted, just in different ways.

Subject contrast is dependent on the:

When the entering x-ray photon loses energy and changes its path of travel as a result of interacting with an atom, the interaction is known as the:

Difference in the brightness levels or densities is:

Which of the following is an advantage to film-screen imaging when compared to digital imaging?
