Publication number: 20190336086Abstract: An interferometer grating support (118) of an imaging system (100) configured for grating-based x-ray imaging includes at least two elongate supports (302) separated from each other by a non-zero distance, wherein the at least two elongate supports have a first end (312) and a second end (316). The grating support further includes a first arc shaped grating (202) affixed to the first end and a second arc shaped grating (204) affixed to a second end (316). A non-transitory computer readable medium is configured with computer executable instructions which when executed by a processor of a computer cause the processor to: move a grating support, which supports G0 and G1 gratings of an interferometer and a bowtie filter, into a region between a low energy photon filter and a beam collimator, which are between a radiation source and an examination region, for a grating-based x-ray imaging scan.Type: ApplicationFiled: November 30, 2017Publication date: November 7, 2019Applicant: KONINKLIJKE PHILIPS N.V.Inventors: ROLAND PROKSA, THOMAS KOEHLER

Publication number: 20190336087Abstract: The invention relates to a problem of setting mutual position of an anatomy being imaged and imaging means of a computed tomography imaging apparatus so that specifically the very volume of the anatomy desired to be imaged actually is imaged. To further the positioning, a positioning tool in a form of a three-dimensional virtual positioning model (40), generated from the anatomy to be imaged, is shown on a display from which the volume (41) of the anatomy desired to be imaged can be pointed, selected or defined.Type: ApplicationFiled: December 15, 2017Publication date: November 7, 2019Inventors: Mikko JARVA, Kustaa NYHOLM

Publication number: 20190336089Abstract: According to one embodiment, an X-ray computed tomography apparatus includes an X-ray tube, a detector, and processing circuitry. The X-ray tube emits X-rays. The detector detects X-rays that have been emitted from the X-ray tube and have passed through the subject. The processing circuitry sets an imaging condition. The processing circuitry evaluates the imaging condition based on information on a lower limit range of a count value of the detected X-rays that may cause image degradation.Type: ApplicationFiled: April 23, 2019Publication date: November 7, 2019Applicant: Canon Medical Systems CorporationInventor: Takahiro GOTO
