Oral radiology: principles and interpretation. There was no significant difference between new and used IPs. There were no significant differences for up to 1000 exposures, and no significant difference was observed among images scanned with a delay of up to 3 h in new and used IPs.
Statistical analysis was performed by ANOVA and use of Dunnett’s multiple comparison test ( P < 0.05). Immediately scanned pixel data were used as baseline for comparison. Image gray value (IGV) in each image was calculated for statistical analysis. These images were exported as 24-bit tiff files with 8-bit gray value data, and mean gray values (MGVs) were measured and compared. Images without automatic gain control were used in both analyses. The exposed IPs were then scanned 0, 5, 10, 30, and 60 min, and 3, 24, 72, and 144 h after exposure. The first exposure image data were used as baseline for comparison. Three new and three used IPs were tested for signal fading, and the other two new IPs were exposed 1000 times and then tested for durability. The materials examined consisted of eight IPs.
To assess the durability of the imaging plates (IP) supplied with the Digora Optime ® digital imaging system in terms of their functionality after as many as 1000 exposures and the degree of signal fading that occurred after a delay of up to 144 h between exposure and scanning Methods
