In the answer booklet simply provide the name of the imaging method with the appropriate numbers corresponding to the item number. List of items Imaging Methods 1. optical density 2. steering electrodes 3. photocathode 4 photostimulable phosphor 5. gamma slope 6. laser scanning readout 7. fluoroscopy 8. Similar to TLD technology 9. silver bromide crystal put appropriate item numbers XRII Computed Radiography Screen Film Radiography In your answer booklet provide answer in above formatExplanation / Answer
1. Optical density is the amount of metallic silver developed on screen in order to parameterize image quality in Screen Film radiography.
2. Steering electrodes are used in XRII in order to intensify the image.
3. The photocathode is also used in XRII for obtaining an image.
4.A photostimulable phosphor is used in computed radiography to obtain X-ray digital image.
5. Gamma slope is used in Screen Film Radiography to get the relation between optical density and exposure time.
6. Laser scanning readout is used in Computed Radiography to convert X-ray energy in terms of digital signals.
7. Fluoroscopy is used in Screen Film Radiography and XRII to get an image on a film or to view directly.
8.Similar to TLD technology used in Computed Radiography.
Silver Bromide crystals are used in Screen Film Radiography to make a film.
