Other advantages of PSP systems include being available in exactly the same size as conventional film and having a wider dynamic range, which produces better quality radiographs compared with CCD and CMOS sensors. PSP image receptor systems are distinguished from other types by special features of the plate-thin structure and flexibility-and by the absence of an electrical cord, qualities that make it easier to place the receptor into the mount. In actuality, the PSP system can be referred to as a semidirect imaging system. These digital image receptors are also broadly classified as direct (CCD, CMOS) and indirect (PSP). Several systems have been introduced for intraoral digital radiography, and they can be divided into three groups according to their sensor types : Charge-Coupled Device (CCD), Complementary Metal Oxide Semiconductor (CMOS), and Photostimulable Phosphor Plate (PSP). Introductionĭue to advancements in technology, digital radiography is widely used in dental practice. Within the limitations of the current study, it can be concluded that scanning delay causes a reduction in image quality, and using the manufacturer's original protective case will result in better performance of PSPs. Reduction in image quality began 5 min after exposure in the other Dürr plate groups. MGVs increased with increasing scanning delay, except the group with Dürr plates in their original cases. ANOVA revealed that the MGVs of four steps of the wedges were significantly different from each other for all scan delays ( ).
Statistically significant differences were found between the two PSPs ( ). Mean gray values (MGVs) of the 3rd, 5th, 7th, and 9th steps of the wedges were compared using ANOVA. These plates were placed in three different protective plastic cases (manufacturers' original cases, black case, and white case) before obtaining the radiographs and were then processed immediately and 1, 5, 10, 30, 60, 120, 240, and 480 min after exposure. Two PSPs using an aluminum step wedge were exposed. The purpose of this study was to analyze two phosphor plate systems (PSPs) (Dürr Dental, Digora Optime) according to their scanning delay and protective plastic case performances.
DIGORA OPTIME SCANNER PROFESSIONAL
In Dominic Foyster we have found a professional whose values line up with our own. I am keen to recommend Dominic and Imaging Technologies to any clinic looking for top products backed by technical know-how in spades. Please feel free to email me in this respect.Objective. Obviously with a whole new system we did have a few teething problems – in each case Dominic attended the clinic either the same day or within 24 hrs to sort the problem.Īt Winning Smiles we pride ourselves on the quality of our delivery, back up and efficiency. I was impressed with Dominic’s knowledge, and the Vatech scanner images which appeared far better resolved than the images from other units that I was used to. Once Dominic had put a comprehensive package together (including a complete new digital suite for 2D radiographs)I felt I was dealing with the right company and signed up. Signing up with new 3rd party companies is always a leap in the dark because –regardless of the rhetoric one never knows how good the after-sales service will be. To my relief I have found the back up to be first class. At that point I had had a few meetings with companies touting CT machines. I first came across Dominic Foyster and Imaging Technologies in January 2010 when I was looking for a CBCT scanner for my clinic.
