An extra-oral digital panoramic dental x-ray imaging system is disclosed for multi-layer panoramic and transverse X-ray imaging. The system includes an X-ray source and a digital imaging device capable of “real time” frame mode output. The source and imaging device are mounted in a mechanical manipulator defining the trajectory of a predetermined image layer. The imaging device communicates with a processor that generates a frames memory from which an image reconstruction mechanism composes the final images. For “real time” imaging, the frames memory is a fast data storage system such as RAM. The processing unit executes the reconstruction algorithms, allowing the system to selectively generate dental panoramic X-ray images, dental transverse x-ray images and dental tomosynthetic 3D images. |
