    • D.

      None of these

    Correct Answer
    C. CMOS/CCD
    Explanation
    CMOS/CCD is the most cost-effective small animal system because it refers to complementary metal-oxide-semiconductor (CMOS) and charge-coupled device (CCD) technologies, which are known for their low cost and high performance. These technologies are commonly used in digital imaging systems, including small animal systems, due to their affordability and ability to produce high-quality images. Therefore, CMOS/CCD is the most cost-effective option among the given choices for a small animal system.

    Which Digital System produces the highest resolution, 5-10 Lp/mm?

    • A.

      CR - computed radiology

    • B.

      DR

    • C.

      CMOS/CCD

    • D.

      None of these

    Correct Answer
    A. CR - computed radiology
    Explanation
    CR - computed radiology produces the highest resolution of 5-10 Lp/mm. This technology uses a phosphor screen to capture X-ray images, which are then converted into digital format. The resulting images have a high level of detail and clarity, making CR an ideal choice for applications that require high-resolution imaging, such as mammography or dental radiography. DR (digital radiography) and CMOS/CCD (image sensors) are also digital systems, but they may not offer the same level of resolution as CR. Therefore, the correct answer is CR - computed radiology.

    What is the most expensive part of a DR-type system?

    • A.

      Computer

    • B.

      Digital Converter

    • C.

      Wire

    • D.

      Flat Panel Imaging Plate

    Correct Answer
    D. Flat Panel Imaging Plate
    Explanation
    The most expensive part of a DR-type system is the Flat Panel Imaging Plate. This component is responsible for capturing the X-ray images and converting them into digital format. It is a high-quality and advanced technology that requires precision manufacturing and materials, making it costly compared to the other options listed. The computer, digital converter, and wire are essential parts of the system but generally less expensive in comparison.

  • 5. 

    Which system is the most versatile for either large or small animal use?

    • A.

      CR - computed radiology

    • B.

      DR

    • C.

      CMOS/CCD

    • D.

      None of these

    Correct Answer
    A. CR - computed radiology
    Explanation
    Computed radiology (CR) is the most versatile system for both large and small animal use. CR allows for the capture of digital images using a cassette-based system, making it suitable for a wide range of animal sizes. It offers flexibility in terms of image acquisition and can be used for various imaging modalities, including radiography, fluoroscopy, and mammography. Additionally, CR systems can be easily integrated into existing radiology departments, making them a convenient choice for both large and small animal clinics.

    Rate this question:

  • 6. 

    Which system is the slowest in producing the image?

    • A.

      DR

    • B.

      CMOS/CCD

    • C.

      Both A & B

    • D.

      CR - computed radiology

    Correct Answer
    D. CR - computed radiology
    Explanation
    CR - computed radiology is the slowest in producing the image because it uses a cassette-based system where the image is captured on a photostimulable phosphor plate. This plate then needs to be processed in a separate machine to produce the digital image. On the other hand, DR (digital radiography) and CMOS/CCD (charge-coupled device) systems produce images almost instantly as they directly convert X-rays into digital signals, eliminating the need for additional processing steps. Therefore, CR is slower compared to the other options.

  • 7. 

    Which digital system is the most expensive to service?

    • A.

      CR - computed radiology

    • B.

      DR

    • C.

      CMOS/CCD

    • D.

      None of these

    Correct Answer
    B. DR
    Explanation
    DR stands for Digital Radiography, which is a digital imaging technology used in medical imaging to capture X-ray images digitally. Compared to CR (Computed Radiology) and CMOS/CCD (Complementary Metal-Oxide-Semiconductor/Charge-Coupled Device), DR systems are generally more expensive to service. This is because DR systems use more advanced technology and require specialized equipment and expertise for maintenance and repairs. Therefore, the correct answer is DR.

    What is the temperature limitation of a DR Selenium Flat Panel system?

    • A.

      25-75 degrees F

    • B.

      35-85 degrees F

    • C.

      45-95 degrees F

    • D.

      105-135 degrees F

    Correct Answer
    C. 45-95 degrees F
    Explanation
    The temperature limitation of a DR Selenium Flat Panel system is 45-95 degrees Fahrenheit. This means that the system can operate within this temperature range without any issues. Operating the system outside of this range may result in malfunction or damage to the equipment.

  • 9. 

    Which system can be shared with more than one patient at a time.

    • A.

      CR

    • B.

      DR

    • C.

      CMOS/CCD

    • D.

      None of these

    Correct Answer
    A. CR
    Explanation
    CR stands for Computed Radiography, which is a system that uses a cassette-based imaging plate to capture X-ray images. Unlike DR (Digital Radiography), CR plates can be shared with multiple patients at a time. This is because the imaging plate can be removed from the cassette and inserted into a separate reader, allowing for efficient and cost-effective sharing of the system among multiple patients. CMOS/CCD refers to image sensors used in digital cameras and does not pertain to the sharing of systems among patients. Therefore, the correct answer is CR.

  • 10. 

    Which type of Digital System is the only direct conversion image capture system? That operates without an image capture screen for semiconductor light capture.

    • A.

      CR - computed radiology

    • B.

      DR - Silicon

    • C.

      DR - CMOS/CCD

    • D.

      DR - Selenium

    Correct Answer
    D. DR - Selenium
    Explanation
    DR - Selenium is the only direct conversion image capture system that operates without an image capture screen for semiconductor light capture. Selenium is a material that directly converts X-ray photons into an electrical charge, eliminating the need for an image capture screen. This makes DR - Selenium a more efficient and direct method of capturing images compared to other options like CR - computed radiology or DR - Silicon, which require additional steps in the image capture process.
