2023 marked the 40th anniversary of phosphor stimulated radiography's first clinical use. Over the past four decades, the materials and technology used in phosphor plate radiography has continued to get better and enhance the quality and speed of dental x-rays. Despite the obvious advantages of digital radiography, many practices have not yet converted from their traditional x-ray methods. This can be down to budget restrictions, training concerns or a general lack of knowledge around the subject.
Phosphor plate radiography is considered by many to be the least expensive way to convert from analogue to digital imaging and have the easiest learning curve.
What Are the Advantages of Phosphor Plate Radiography?
Phosphor plate radiography holds several advantages over analogue x-rays and other digital x-ray systems.
- Reduced chairtime - Radiographs are produced in a matter of seconds.
- Clearer images - Digital x-rays are generally considered to produce shaper, higher quality images.
- Capture more - The entire plate is capable of image capture unlike hard-wired (HR) digital sensors which usually have some inactive area.
- Less radiation - Phosphor plates produce up to 90% less radiation compared to traditional x-rays.
- Digital enhancement - Helps assist in diagnosis and patient education.
- Less waste - No need for chemicals to process images and there is no film to dispose of.
- Easy sharing - Digital radiographs can be shared rapidly with other dental professionals.
- Smooth transition - The technique is near identical to analogue.
- Cheapest digital option - The costs involved are generally cheaper than buying a top-end HR digital sensor system.
- Patient friendly - Phosphor plates are flexible and can be well-tolerated in the posterior regions of the mouth - unlike some rigid and bulky HR sensors.
Can Phosphor Plates Be Reused?
Studies have found that phosphor plates can be used at least 200 times before they begin deteriorating and need replacing. Theoretically there is no limit to the number of times a plate can be used if handled carefully and under certain radiation exposure conditions.
How Easy is It to Convert to Phosphor Plate?
Phosphor imaging plates can be easily retrofitted to existing rooms and used in multiple x-ray sites since digital imaging scanners can be shared between multiple rooms. The initial purchase of a digital scanner will be the most expensive part of the conversion process, but this machine can last a lifetime with proper maintenance. The compact and wireless Acteon PSPIX2 phosphor image plate scanner is the only scanner on the market with optional removable parts that can be sterilised in an autoclave to give maximum protection.
