SYSTEMS, DEVICES, AND METHODS FOR MULTISOURCE VOLUMETRIC SPECTRAL COMPUTED TOMOGRAPHY
20230375484 · 2023-11-23 ·

A multisource volumetric spectral computed tomography imaging device includes an x-ray source array with multiple spatially distributed x-ray focal spots, an x-ray beam collimator with an array of apertures, each confining the radiation from a corresponding x-ray focal spot to illuminate a corresponding segment of an object, a digital area x-ray detector, and a gantry to rotate the x-ray source array and the detector around the object. An electronic control unit activates the radiations from the x-ray focal spots to scan the object multiple times as the gantry rotates around the object. The images are used to reconstruct a volumetric CT image of the object with reduced scattered radiation. For dual energy and multi energy imaging, radiation from each focal spot is filtered by a corresponding spectral filter to optimize its energy spectrum.
