What is phosphor storage plate imaging?
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.
What is storage phosphor?
Photostimulable phosphors (PSPs), also called storage phosphors, are compounds that are capable of absorbing and storing energy from x-rays. They can be stimulated subsequently to release energy in the form of visible light.
How does a phosphor plate work?
In phosphor plate radiography, the imaging plate is housed in a special cassette and placed under the body part or object to be examined and the x-ray exposure is made. The imaging plate is then run through a special laser scanner, or CR reader, that reads and converts the image to a digital radiograph.
Are phosphor plates digital?
Storage phosphor plates (SPP) are indirect digital image receptors. The CCD direct digital image receptor was the first digital image receptor used in intraoral radiography.
What system are phosphor plates used in?
Computed radiography (CR) systems are very similar to film-based systems, but instead of film, a photostimulable phosphor plate is used. These flexible plates are 1 mm thick and are coated with europium activated fluorohalide compounds in crystalline formation embedded in organic binding material.
How long do phosphor plates last?
According to the manufacturers, the plates will lose their ability to capture a diagnostic image after 750 to 1,000 uses. In reality, few offices will see these results. The plates are easier to scratch and damage, and most offices will be lucky to get 500 uses out of each plate.
Can phosphor plates be reused?
The findings of this study revealed that even though a slight deterioration occurred after the first exposure, each plate can be used up to 200 times.
What happens to a storage phosphor plate after it is scanned?
A filter in front of the PMT absorbs the reflected laser light and transmits the phosphor emission light (Figure 4). In the PMT, the light signal is transformed into an electrical signal, amplified, digitized and stored in a computer file. After erasure the plate is re-inserted into the cassette for re-use.
How many times can a phosphor plate be used?
Conclusions: The findings of this study revealed that even though a slight deterioration occurred after the first exposure, each plate can be used up to 200 times.
How do you clean phosphor plates?
How do I clean the Phosphor Storage Plates?
- Use lint-free, 100% cotton gauze (not cotton balls).
- To clean any remaining stains, dampen the gauze in anhydrous ethanol or anhydrous isopropyl alcohol and wipe using the same motion as above.
- Completely dry the surface by wiping with another piece of cotton gauze.
What is a dental phosphor plate?
Our dental phosphor plate systems will accurately read the latent dental X-ray image on a phosphor storage imaging plate (PSP). Phosphor imaging plates are an economical option for intraoral imaging and their rail thin design with zero cabling or wires makes them extremely user friendly.
Are phosphor plates better than X-ray sensors?
While phosphor plates are not as rapid and nimble as the wired systems, they do work great as backup systems and for days with heavy patient volumes. There is a fine line when trying to determine the difference in dental imaging quality between phosphor plates and dental x-ray sensors.
Can phosphor plate be delivered pre-packaged?
Phosphor plate cannot be delivered pre-packaged. Each plate needs to be packaged in its protective envelope before it’s ready for use, which increases preparation time for the X-ray procedure. Today, 4 out of every 10 dental practices have moved from conventional radiography to digital imaging.
Do digital phosphor plate systems improve radiography processing time?
Even with the use of digital phosphor plate systems, there’s no significant improvement in radiography processing time. Digital imaging through this technology takes almost the same time as conventional films. Phosphor plates are light-sensitive and need to be handled with extreme care. They need to be placed inside a protective envelope after use.
