What is digital radiography?
✔✔ A form of imaging that uses digital detectors to capture and display images.
What is the main advantage of digital radiography over film-based radiography?
✔✔ Faster image acquisition and processing.
What is the function of a digital detector in radiography?
✔✔ To capture the X-ray image for digital display and analysis.
What does PACS stand for in digital imaging?
✔✔ Picture Archiving and Communication System.
What is the purpose of DICOM in digital radiography?
✔✔ It provides a standard format for storing and transferring medical images.
1
,What is spatial resolution in digital radiography?
✔✔ The ability to distinguish small details in the image.
What is the role of pixel size in image quality?
✔✔ Smaller pixels provide better image resolution.
What is a flat-panel detector?
✔✔ A type of digital detector used to capture X-ray images.
What is the function of a scintillator in a digital detector?
✔✔ To convert X-rays into visible light for image capture.
What does the term "contrast resolution" mean in digital imaging?
✔✔ The ability to differentiate between tissues of similar densities.
What is the role of preprocessing in digital radiography?
✔✔ To enhance the raw image data for optimal quality.
2
, What is exposure latitude in digital imaging?
✔✔ The range of exposure values that produce acceptable image quality.
What is the main component of a digital imaging receptor?
✔✔ A detector that captures and converts X-rays into digital data.
What is the purpose of a histogram in digital radiography?
✔✔ To represent the distribution of pixel intensities in the image.
What is automatic rescaling in digital imaging?
✔✔ Adjusting the image brightness and contrast for consistency.
What is the significance of a high signal-to-noise ratio (SNR)?
✔✔ It indicates better image quality with less noise.
What is the purpose of a lookup table (LUT) in digital radiography?
✔✔ To adjust image brightness and contrast based on predefined parameters.
