How does the central ray (CR) for an anteroposterior (AP) scapula differ from an AP shoulder x-ray?

• CR is the same.

• One inch lower.

• One inch higher.

• Same level, medial.
• One inch lower.

The CR for an AP scapula is one inch lower than the CR for an AP shoulder, or two inches inferior to the coracoid process. The CR is not the same for these two projections. One inch higher is at the level of the coracoid process, too high. At the same level, but medial, will be one inch too high.Where is the central ray (CR) directed for an anteroposterior (AP) projection of the lower leg?

• At the level of the medial malleolus.

• Two inches distal to the medial condyle of the tibia.

• Mid-lower leg. 1 / 4

• 0.5 inch inferior to patellar apex.
• Mid-lower leg.

An AP projection of the lower leg requires the CR to enter mid-lower leg. Half an inch inferior to the patellar apex, the level of the medial malleolus, and two inches distal to the medial condyle of the tibia are all either too high or too low.What should the radiographer do if a radiologist's instructions are unclear?

• Question the lead technologist.

• Perform the exam in the usual way.

• Read the protocol book.

• Ask for clarification
• Ask for clarification

The radiographer should ask for clarification. This will allow for any miscommunication to be corrected and improve the patient outcome. The other options are incorrect.

• The radiographer.

A metallic artifact from an object that can be clearly seen as the patient is positioned is clearly the responsibility of the radiographer. For those who would argue that the radiographer is not responsible for caps on teeth, notice that the head is tipped too far forward. The occipital bone is not even visualized on this image. This cap need not have obscured the tip of the odontoid process. No one else is responsible in this case.Who is responsible for the metallic artifact seen in the open mouth odontoid image?

Which step will reduce digital image noise, assuming no other changes?

• Longer exposure time.

• Image magnification.

• Decreased kilovolts peak (kVp).

• Small pixel size.
• Longer exposure time.

A longer exposure time results in a greater amount of photons reaching the image receptor, which reduces image noise. Decreased kVp reduces the quantity of x-rays that reach the image receptor, which increases image noise. A matrix with a large number of small pixels results in greater image noise due to the availability of fewer photons per pixel. Magnification of the digital image does not affect image noise, but it may make what noise is there more visible.Which system can store images?

• Picture archival and communication system (PACS).

• Hospital information system (HIS).

• Digital imaging and communication in medicine (DICOM).

• Radiology information system (RIS). 3 / 4

• Picture archival and communication system (PACS).

The PACS can store images. The HIS contains much information, including billing information and patient treatment plans, but does not contain images. Likewise, the RIS does not contain images, though it has radiology-specific information, such as a radiology schedule history. The DICOM standard allows images to be exchanged between different devices.Which action can improve recorded detail?

• Use the largest focal spot.

• Increase the source-image receptor-distance (SID).

• Select a larger kilovolts peak (kVp).

• Increase the object-image receptor-distance (OID).
• Increase the source-image receptor-distance (SID).

Increasing the SID will cause an increase in recorded detail on the image. Increasing the OID, or using a larger focal spot will all cause a decrease in recorded detail. KVp does not affect recorded detail.What is the maximum speed of filament electrons as they travel toward the anode?

• One-eighth the speed of light.

• Half the speed of light.

• One-fourth the speed of light.

• The speed of light.
