The purpose of the study was to compare the image generated by a classic panoramic machine equipped with a cadmium telluride sensor capable of digital tomosynthesis and special software with images produced by other popular panoramic X-ray machines using a charge-coupled device and native software for image capture.
Panoramic images were made using a phantom of a human skull on Planmeca ProMax, Planmeca EC Proline, Kodak 8000 and PC-1000. With the last machine we used the PanoACT® software to adjust the entire arch and to adjust the image in selected regions of interest (ROIs). Ten viewers evaluated the images and provided the viewer data. ANOVA for repeated measures was used to compare the means by pairwise comparisons of means.
The image of the entire arch adjusted by the PanoACT® software was statistically superior to the images produced by other machines. The images generated and individually adjusted by PanoACT® were statistically superior to all other images.
The image generated by the cadmium telluride sensor has great potential and can be processed to create superior images to those taken with other machines. Furthermore, the ROI individual images enhanced by the PanoACT® were superior to the entire arch adjusted by the same software.
本研究的目的是比较配备碲化镉传感器的经典全景机与特殊软件生成的数字断层图像与其他使用电荷耦合器件和原始软件进行图像采集的流行全景 X 射线机生成的图像。
使用人体颅骨模型在 Planmeca ProMax、Planmeca EC Proline、Kodak 8000 和 PC-1000 上制作全景图像。对于最后一台机器，我们使用 PanoACT®软件来调整整个弓，并在感兴趣区域（ROI）中调整图像。十位观察者评估图像并提供观察者数据。采用重复测量方差分析进行两两比较的均值比较。
通过 PanoACT®软件调整的整个弓的图像在统计学上优于其他机器生成的图像。由 PanoACT®生成和单独调整的图像在统计学上优于所有其他图像。
碲化镉传感器生成的图像具有很大的潜力，可以进行处理以创建优于其他机器拍摄的图像。此外，通过 PanoACT®增强的 ROI 个别图像优于通过相同软件调整的整个弓。
