Effects of Processing Delays in Different Coverages on the Image Quality of Photostimulable Phosphor Plates With Acteon and Digora Scanners

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 ), semitransparent (A2 B2 original dark case (A3 B3 ). An aluminum step wedge was subjected constant exposure conditions. The exposed immediately processed their corresponding scanner device (the golden standard), 5, 10, 20, 30, 40, 60 minutes after exposure. average gray level information 2nd, 5th, 8th steps Al considered as mean values (MGVs) each wedge. difference between 2nd measured contrast. Results: There significant contrast MGVs at all delay times (P<0.05). In general, there no any scanners (total P>0.05). subgroup, increased, while decreased by increasing time; except for first 5 A1 (P=0.12) A3 (P=0.06). Conclusions: Thus, type effective quality; PSP coating few could affect rate loss. However, scan time greater effect amount
