Film images exhibit significantly higher spatial resolution than the RVG images acquired in high-resolution mode. In periodontal mode, the RVG UI sensor demonstrates exposure latitude similar to that of Ektaspeed Plus film. Modulation transfer function measurements supported the subjective assessments. The average maximum resolution was 15.3 line-pairs per millimeter (lp/mm) for RVG in high-resolution mode, 10.5 lp/mm for RVG in low-resolution mode, and 20 lp/mm for film (P <.0001). Other gray scale modes demonstrated much lower latitude. The RVG was further characterized by its modulation transfer function.Įxposure latitude was equal for film and RVG in the periodontal mode. Latitude and resolution were assessed by observers for both modalities. Spatial resolution was assessed by using a line-pair test tool. RVG FIRST is where affordability and quality combine. Dose-response curves were generated for film and for each of 6 available RVG modes. With a true resolution of 14 lp / mm it is a powerful yet economical solution to fully streamline your digital workflow. Spatial resolution was assessed by using a line-pair test tool. This study compares the physical characteristics of the RVG UI sensor (RVG) with Ektaspeed Plus film. An aluminum step-wedge was used to evaluate exposure latitude.
