objectives: this study aimed to assess the diagnostic value of conventional and digital radiography for detection of cavitated and non-cavitated proximal caries. materials and methods: fifty extracted human premolars and molars were mounted in a silicone block. charge-coupled device (ccd) and photostimulable phosphor plate (psp) receptors and intra-oral films were exposed with 60 and 70 kvp wit...

Background: Delay in the processing of photostimulable phosphor storage plates (PSP) is a common occurrence crowded clinics. Accordingly, effects delays different coverages on image quality PSPs were investigated with Acteon and Digora scanners. Methods: Three (group A) three B) used this vitro study. Each group had subgroups according to coverages, including protective box (A1 , B1 ), semitran...

The recommended methods to test the performance of computed radiography (CR) systems have been established by The American Association of Physicists in Medicine, Report No. 93, “Acceptance Testing and Quality Control of Photostimulable Storage Phosphor Imaging Systems”. The quality assurance tests are categorized by how frequently they need to be performed. Quality assurance of CR systems is th...

Persistent phosphors have the ability to emit light long after the excitation has ended, typically by using thermal energy to liberate previously trapped charges. Alternatively, also photons can be used for the detrapping, leading to optically stimulated luminescence (OSL). This particular field of phosphor research has seen a strong expansion over the past two decades, with a steady growth of ...

PURPOSE This study tested an infection control protocol for photostimulable phosphor (PSP) sensors while simulating multiple uses. METHODS Dental hygiene students (n=36) were randomly assigned to a control group (dry wipe) or test group (disinfectant wipe). A sterile, barriered sensor was placed in a peer patient's mouth to simulate an exposure. After simulation, the barriered sensors were di...

Abstract. Breast imaging techniques have received renewed attention as a proved means for earlier detection and diagnosis of breast cancer. Due to the extremely high image quality requirements in mammography, all aspects of the imaging process must be optimised. With this purpose new imaging systems have been incorporated. The aim of this paper is to present results of patient dose comparison i...

PURPOSE The purpose of this study was to compare the number and type of technical errors between 2 rectangular collimators, time/motion effort and radiographer preference. METHODS Subjects (n=17) were recruited to expose an 18 projection full mouth series (FMX) using Tru-Align™ (enhanced) and Rinn® (universal) collimator devices. Both FMXs were exposed using photostimulable phosphor (PSP) dig...
