Patent number: 11678850Abstract: A photon-counting X-ray detector includes a converter element constructed to convert incident X-rays into electrical signals in dependence on a deposition of energy in the converter element, and an evaluation device. The evaluation device includes a pulse-generator to generate and output an electrical pulse based upon an electrical signal fed from the converter element; a differentiator to generate a differentiated signal of the electrical pulse output by the pulse-generator; and a first comparator to compare the generated differentiated signal with a first threshold value and, based upon the comparison, to output a binary output signal for a period for which the threshold value is exceeded.Type: GrantFiled: June 22, 2021Date of Patent: June 20, 2023Assignee: SIEMENS HEALTHCARE GMBHInventors: Martin Hupfer, Edgar Goederer

Patent number: 11675096Abstract: An X-ray detector includes a converter element for converting X-rays into electric signals; and a plurality of pixel elements. In an embodiment, each pixel element includes a first signal processing stage for processing respective electric signals with at least one signal amplifier and at least one comparator for providing a digital pixel signal. The signal outputs of the first signal processing stage of at least one group of pixel elements are coupled via signal technology to a common second signal processing stage including a multiplicity of digital logic elements. The common second signal processing stage includes a configurable switching matrix for interconnecting at least one partial number of the multiplicity of digital logic elements with the respective signal outputs of the first signal processing stage, so that, following a configuration of the switching matrix, a processing chain can be provided for the digital processing of the digital pixel signals.Type: GrantFiled: December 9, 2020Date of Patent: June 13, 2023Assignee: SIEMENS HEALTHCARE GMBHInventors: Edgar Goederer, Martin Hupfer, Bjoern Kreisler, Martin Petersilka

Publication number: 20210186440Abstract: A photon-counting X-ray detector is for acquiring an X-ray image data set of an object penetrated by X-ray radiation. The detector includes a converter element, designed to convert incident X-ray radiation into an electrical signal; and a matrix with a plurality of pixel elements. At least a partial number of the plurality of pixel elements receive a signal input and at least one configurable counter is coupled to the at least a partial number of the plurality of pixel elements, for signaling. Further, the at least one configurable counter is designed to count either a pixel count signal, based on a signal directly received in each respective pixel element, or a coincidence count signal, based on the signal received directly in the respective pixel element and on a coincident signal of at least one further pixel element.Type: ApplicationFiled: December 9, 2020Publication date: June 24, 2021Applicant: Siemens Healthcare GmbHInventors: Bjoern KREISLER, Edgar GOEDERER, Martin HUPFER, Martin PETERSILKA
