METHOD FOR MULTI-ENERGY X-RAY IMAGING, X-RAY FACILITY, TREATMENT SYSTEM, COMPUTER PROGRAM AND ELECTRONICALLY READABLE DATA CARRIER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18198541 titled 'METHOD FOR MULTI-ENERGY X-RAY IMAGING, X-RAY FACILITY, TREATMENT SYSTEM, COMPUTER PROGRAM AND ELECTRONICALLY READABLE DATA CARRIER
Simplified Explanation
- The patent application describes a method for multi-energy X-ray imaging to display contrast material in a field of view. - The contrast material has a high atomic number (at least 65) or a high k-edge (at least 60 keV). - Two image datasets with different X-ray spectra are recorded and combined to obtain display information of the contrast material. - Spectrally acting filters are used to generate the X-ray spectra from the X-ray source. - The filters are designed to maximize the differential spectrum, which includes a range of higher absorption by the contrast material starting from its k-edge.
Original Abstract Submitted
A method is provided for multi-energy X-ray imaging of a field of view in order to display a contrast material, located in the field of view, having an atomic number of at least 65, (e.g., at least 73), and/or a k-edge of at least 60 keV. In the method, two image datasets having different X-ray spectra are recorded and are combined in order to ascertain display information of the contrast material, wherein the X-ray spectra are generated by using at least one spectrally acting filter, starting from a source spectrum of an X-ray source in such a way that the value of their differential spectrum has a maximum, which includes a range, beginning at the k-edge of the contrast material, of higher absorption by the contrast material.
