Exploring Radiographic Imaging

What is the primary purpose of radiography examination?

• To produce diagnostic images of internal body structures.

• To reduce radiation exposure to patients.

• To enhance the color of images.

• To create 3D models of body structures.

Basic components of a film-screen radiography system is

• X-ray tube, film, screen, film holder (cassette)

• X-ray generator, digital sensor, imaging plate, control panel

• Lead apron, collimator, grid, exposure timer

• Radiation detector, image processor, display monitor, patient table

What the difference between computed radiography and conventional film-screen radiography?

• Computed radiography requires more radiation exposure than conventional methods.

• Conventional film-screen radiography is faster than computed radiography.

• Computed radiography uses physical film for imaging.

• Computed radiography uses digital imaging plates, while conventional film-screen radiography uses film.

The advantage of computed radiography is

• Improved image quality

• Limited image storage capacity

• Longer processing times

• Higher radiation exposure

Digital radiography

• acquired images by scanning the patient with a laser instead of X-rays.

• involves using film to capture images directly from X-rays.

• does not require any image processing after detection.

• involves using flat panel detector as image receptor

What are the main benefits of digital radiography over film-screen methods?

• Longer processing times for images

• Increased risk of image distortion

• Easier image storage and sharing of images.

• lower installation costs

Digital fluoroscopy is

• Static imaging for dental assessments

• Routine blood tests

• Patient consultations for mental health

• Real-time imaging during surgeries

How is radiographic image quality assessed?

• based on the technician's experience.

• determined by the patient's age.

• evaluating contrast, resolution, noise, and artifacts.

• based on the duration of the exposure.

What factors influence the quality of digital radiographic images?

• Patient age and gender

• Exposure setting

• Time of day the image is taken

• Type of radiation used

The role of image processing in digital radiography is

• Image processing is only used for enhancing color in images.

• Image processing improves the quality of the images, aiding in accurate diagnosis.

• Image processing reduces the size of digital radiographic images.

• Image processing has no impact on the diagnosis process.
