RAD 217 Exam 3 Review

A detector in which each pixel has its own amplifier is known as a

• CCD.

• field-effect transistor.

• CMOS.

• thin-field transistor.

RAM is

• permanent for the CPU.

• long term for archiving.

• temporary for the BIOS.

• short term for open programs.

The microprocessor uses the BIOS during

• start-up diagnostics.

• the shutdown process.

• processing algorithm application.

In which system architecture do the acquisition modalities send their images directly to a designated workstation?

• Client/server-based system

• Distributed system

• Web-based system

• Image manager system

Loss of detail in a digitally processed image

• occurs because of the number of conversions.

• is extremely minimal compared with film/screen.

• is equal to film/screen.

• has almost no impact on the image.

Proper patient demographic input is the responsibility of the

• technologist.

• QC manager.

• radiologist.

• transporter.

Which of the following is TRUE regarding post-processing functions?

• Early PACS radiologists believed that they needed four to six monitors to view images.

• Digital annotations may safely be used to indicate the right or left side of the patient.

• Incorrect patient demographic information is unimportant in a PACS network.

• All display workstations on the network possess the same post-processing capabilities.
