How is PSP erased?

Unlike film, a PSP plate can be reused: plates can be "erased," by exposing the plate to room-intensity white light.

What erases the PSP?

Erasure may be achieved by placing the PSP on a conventional light box. The time taken to erase the PSP will depend upon the intensity of the light produced (1000–5000 lux) but it should be cleared and ready for reuse in under 2 minutes. The PSP may also be erased using the manufacturer's dedicated erasure system.

How is the imaging plate erased?

The generated digital X-ray image can then be viewed on a computer monitor and evaluated. After an imaging plate is read, it is erased by a high-intensity light source and can immediately be re-used - imaging plates can typically be used up to 1000 times or more depending on the application.

What is a PSP in dental radiology?

Photostimulable phosphor (PSP) plates are still widely used as receptors in intraoral radiography. These image receptors allow indirect digital image acquisition; more specifically, after the exposure, latent image occurs on the plate, it is then converted to a digital radiographic four image via a scanning device.

How often should imaging plates be erased?

Too frequent cleaning of the phosphor screens can discolor the phosphor. The imaging plate that have not been used for more than 24 hours should be erased before use.

How to reset a PSP to factory settings

What is a PSP backed by and what does it absorb?

The PSP cassette looks like the conventional screen-film cassette. It consists of a durable, lightweight plastic material (Figure 4-1). The cassette is backed by a thin sheet of aluminum or lead that absorbs backscatter x-ray photons (Figure 4-2).

How is the imaging plate read?

Imaging plates use the principle of phosphorescence. As the name suggests, they do not emit light immediately after x-ray exposure; instead, they store x-ray energy in the form of a latent image. The latent image is later read in the CR machine using a laser.

How are images cleared from the storage phosphor imaging plates?

The images are cleared from the storage phosphor imaging plates by: Being exposed to viewbox light for several minutes.

How does a PSP work?

After a customer enters his card details and clicks 'pay', a transaction request is sent to the payment gateway you've signed up with. The PSP then verifies the customer's card details and checks whether the customer has enough funds in their card account to make the payment.

How often do radiologist miss things?

Research shows that radiologists misdiagnose patients' conditions at least 36% of the time. This is 24% more often than what occurs in any other environment.

Does any radiation stay in the body after an imaging exam?

Does any radiation stay in the body after an imaging exam? After a radiographic, fluoroscopic, CT, ultrasound, or MRI exam, no radiation remains in your body. For nuclear medicine imaging, a small amount of radiation can stay in the body for a short time.

Why is erasing the image is important in radiography?

One way of reducing the probability of obtaining ghost artifacts in a clinical setting is to erase all cassettes at the beginning of the day so that you can ensure it was properly erased. It is also important to erase cassettes before use, after they have set for 24 or more consecutive hours.

What are the disadvantages of PSP plates?

The PSP plates usually do not have a resilient coating, so plates can scratch easily. PSP plates can be damaged by rough handling, heat, and prolonged exposure to bright light.

What are the disadvantages of phosphor plates?

Phosphor plates are light-sensitive and need to be handled with extreme care. They need to be placed inside a protective envelope after use.

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.

Can phosphor imaging plates be damaged?

Photostimulable phosphor plates (PSP) have the advantages that they are thin, flexible and are available in different sizes. The active surface of the plates is, however, prone to damage from scratching, bites and bending. Damaged plates cause artifacts.

How long are radiology images kept?

California law require health care providers to keep x ray film and other medical record for a certain period of time. Hospitals in California must maintain medical records for at least seven years after the date the patient received the last treatment.

What is used in cleaning the imaging plate?

​Cleaning:

You can use a microfibre cloth and a small amount of alcohol rub to clean the imaging plates however, you shouldn't apply the fluid directly to the plate. You should only do this if dirt and artifacts are visible on the x-ray, if no dirt is present then it is not necessary to clean.

Is the PSP gone?

Sony's PlayStation Portable (PSP) store is set to close today, 16 years after the device launched. The move was already confirmed back in April by Sony Interactive Entertainment president and CEO Jim Ryan, where it was originally noted that no purchases would be able to be made from the PSP store from this date.

How to clean my PSP?

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

An image can be erased by simply exposing the plate to a room-level fluorescent light - but more efficient, complete erasure is required to avoid signal carry-over and artifacts. Most laser scanners automatically erase the plate (current technology uses red LED lighting) after laser scanning is complete.
