Aspects include bandwidth reduction in a dental cloud system. By receiving input data representing multiple depth images, partial reconstruction on overlapping images is performed, generating a composite image with significantly reduced data size relative to the input data. This process involves associative operations on depth images, selecting suitable images based on temporal or spatial adjacency, and preserving weight sums for optimal combination. The reconstructed model is transmitted to a remote server for final reconstruction, minimizing required bandwidth. The system integrates low-resolution depth images for swift user feedback and performs global optimization for long-span accuracy. The disclosed approach improves efficiency in dental imaging by reducing data transmission burdens without compromising model accuracy, offering a streamlined approach for cloud-based dental applications.

X-ray tubes that have a reduced exposure time for dental X-ray imaging and 3D dental imaging systems using these X-ray tubes are described. The X-ray tubes contain an anode, a filament, a cathode electrically connected to the filament, and a voltage source electrically connected to the cathode. The voltage source provides a high voltage to the anode relative to the cathode and filament control voltage. A low filament control voltage is used to generate electrons using a process of thermionic emission. These electrons are driven by a large electric field generated between the cathode and anode towards the target on the anode. A bias voltage is applied between the cathode and the filament to control the electron flow from the emitting filament to the anode. Such a configuration yields a switching speed ranging from about 1 ms to about 10 ms, allowing a short X-ray exposure time and a quicker overall imaging process for the 3D dental X-ray imaging systems. Other embodiments are described.
