Hybrid dental imaging system with local area network and cloud
First Claim
1. A method of processing x-ray data, the method comprising:
- acquiring a plurality of x-ray projection frames of at least one object representing at least a portion of a patient, the plurality of x-ray projection frames including first and second frames; and
compressing the plurality of x-ray projection frames to generate a compressed data set, wherein the compressing includes predicting at least one pixel of the second frame based on at least one pixel of the first frame;
providing an x-ray source and an x-ray image detector;
the detector configured to output the first and second frames;
acquiring the first frame while the source and detector are at a first angle with respect to the patient; and
acquiring the second frame while the source and detector are at a second angle with respect to the patient;
wherein the first frame includes a first x-ray projection of at least one object within the patient;
wherein the second frame includes a second x-ray projection of the at least one object and wherein compressing the plurality of x-ray projection frames includes using at least the first and second angles to predict values of pixels representing the second x-ray projection in the second frame.

Abstract
Methods and systems for storing and accessing dental images. The system includes an imaging system for acquiring x-ray projection frames. The imaging system is connected to a local server through a local area network. A cloud server communicates with devices on the local area. The x-ray projection frames are transmitted from the imaging system to the local server. The local server stores the series of related x-ray projection frames according to a specified policy. In one embodiment, the x-ray projection frames are compressed into a compressed image data set using a modified video compression prediction algorithm customized for x-ray images. The x-ray image data (whether compressed or not) is transmitted to the cloud server for storage. The x-ray image data can be accessed from the cloud server by external devices and by other local area networks.
