PANORAMIC IMAGING USING MULTI-SPECTRAL X-RAY SOURCE
First Claim
1. A panoramic x-ray system comprising:
- a gantry;
at least one x-ray source mounted on the gantry and configured to selectively output x-ray radiation having a first energy characteristic and x-ray radiation having a second energy characteristic, the second energy characteristic being different from the first energy characteristic;
a controller configured to control the at least one x-ray source to produce x-ray radiation having the first energy characteristic during a first time period and to produce x-ray radiation having the second energy characteristic during a second time period; and
a receptor mounted on the gantry and positioned to receive x-ray radiation from the at least one x-ray source, the receptor configured to output a first frame of image data based on x-ray radiation received during the first time period and a second frame of image data sequential to the first frame, the second frame based on x-ray radiation received during the second time period.

Abstract
Systems and methods for obtaining a panoramic image. One system includes a gantry, an x-ray source, a receptor, and at least one controller. The x-ray source is mounted on the gantry and is configured to alternatively output x-ray radiation at a first energy level and x-ray radiation at a second energy level. The receptor is mounted on the gantry so that x-ray radiation from the x-ray source impinges the receptor. The receptor is configured to output a plurality of frames of data including a first frame and a second frame sequential to the first frame. The controller is configured to control the x-ray source so that data in the first frame is generated based on x-ray radiation of the first energy level and data in the second frame is based on x-ray radiation of the second energy level.
