Quiz 3Image production/receptor system

100

The two main categories to express digital image quality are image resolution and

image signal.

200

The production of x-radiation that occurs in an X-ray tube requires the movement of negatively charged particles traveling from one side of the tube to the other. This movement of charges must occur in

1. a state of superconductivity.

2. nanospheres.

3.the subnuclear space.

4.a vacuum.

4. A vacuum

300

The loss of radiographic image resolution is often referred to as unsharpness. All of the following contribute to total image unsharpness except the

1. image geometry factors such as OID

2. size and shape of the patient’s anatomy

3. image geometry factors such as SID

4. size and shape of the exposure field (collimation)

4. size and shape of the exposure field (collimation).

400

The reason a vacuum is useful for x-ray production: 

1. This is the site of x-ray production

2. Creates an unimpeded environment for electrons to flow from anode to cathode. 

3. Creates an unimpeded environment for electrons to flow from cathode to anode. 

4.This is the electron source

3. Creates an unimpeded environment for electrons to flow from cathode to anode.

500

As you review a radiographic image of the abdomen of a small child, you notice a small ring-like object on the image. It appears this object is in the patient’s stomach, which is consistent with the examination history. The ring shows on the X-ray image because of its metallic density. This is the result of

1.attenuation of the X-ray beam by the metallic density of the ring.

2.preferential absorption.

3. diffusion weighted absorption.

4.transmission of the X-ray beam through the soft metal of the ring.

1.attenuation of the X-ray beam by the metallic density of the ring.
