How do you clean a photostimulable phosphor plate?

Cleaning Method: Place the plate with the black (non-phosphor) side down on a clean, dry, non-abrasive surface, such as a lint free cloth. Use lint-free cotton to wipe the imaging plates. Use a lint-free cloth dampened with ethanol anhydride to remove stains that do not come off easily.

How do you disinfect a phosphor plate?

There is no reason to routinely disinfect the PSP’s or Plate Guides unless you believe they have been contaminated. If a PSP has touched a contaminated surface, it may be immersed briefly in a cold sterilant according to sterilant manufacturers directions. DO NOT SOAK OVERNIGHT.

What is the purpose of a photostimulable phosphor?

Photostimulable phosphors (PSP) are materials that store absorbed energy within excited electrons and release it in the form of light on exposure to laser energy.

How often should you clean the imaging plates?

Intensifying screens should be cleaned periodically according to the manufacturer’s instructions. Screen cleaners are ideal for removing dirt, dust and fingerprints and should be done regularly. In dryer climates or the wintertime when there is less moisture in the air, static can become a problem.

What is the purpose of europium in a photostimulable phosphor?

What is the purpose of europium in a photostimulable phosphor? The europium is called an activator. It is responsible for electrons being trapped in metastable states.

What is PSP in dentistry?

Intraoral phosphor plate x-ray (also known as phosphor storage plate or PSP x-ray) eliminates the need for traditional film processing for dental radiography. Phosphor storage plates can convert existing film based imaging systems to a digital format that can be integrated into a computer or network system.

How do I clean my Scanx?

Maintenance is minimal. SCANX CLEANING: Turn off the A/T ScanX before cleaning. Wipe the outside surfaces with a paper towel dampened with a disinfectant solution or household, non-abrasive cleaner.

Which type of light will erase a PSP image from the plate?

The x-rays are absorbed by the phosphor layer which will give off PSL after stimulation by the light source. The photons remained trapped in the phosphor center until stimulated by the laser light that reads and erases the image. Differentiate between the point scan and the line scan PSP readers.

What causes a photostimulable phosphor to appear turbid?

What causes a photostimulable phosphor to appear turbid? The small size of the crystals causing them to scatter incident light. The imaging plate is backed with lead to absorb backscatter radiation, which would increase the background noise on the image.

How is the image plate erased?

To erase any residual trapped energy from the imaging plate, a screen is exposed to a bright white light. The imaging plate is then placed back into the cassette to be reused.

How do you clean a digital xray tape?

Clean the inside of the plastic cover of the cassette (tube side panel) using a lint free wipe that has been dampened with a small amount of X-OMAT Screen Cleaner. Dry the cover. It may be advisable to use a soft, lint free brush to remove dust that has accumulated in the corners of the cassette cover, along the hinge.
