Patent number: 11935161Abstract: A method for generating result slice images with at least partially different slice thickness based on a tomosynthesis image data set of a breast includes generating average value slices and maximum value slices (MIP) based on the tomosynthesis image data set, frequency dividing the average value slices into low-pass filtered and high-pass filtered average value slices, high-pass filtering of maximum value slices to form high-pass filtered maximum value slices, mixing high-pass filtered maximum value slices and high-pass filtered average value slices to form mixed high-pass filtered maximum value slices, combining the low-pass filtered average value slices with the mixed high-pass filtered maximum value slices to form the result slice images, and applying a moving maximum value across a selected thickness of maximum value slices or across a selected thickness of mixed high-pass filtered maximum value slices.Type: GrantFiled: September 28, 2021Date of Patent: March 19, 2024Assignee: SIEMENS HEALTHINEERS AGInventors: Marcel Beister, Ludwig Ritschl, Steffen Kappler, Mathias Hoernig

Patent number: 11666292Abstract: A method is for making an X-ray recording of an examination region of an examination object with an X-ray system including an X-ray source arranged on an emitter displacement unit and an X-ray detector including a detection area, arranged on a detector displacement unit. The method includes selecting the examination region and portion-wise recording successive recording portions in relation to the examination region. The portion-wise recording includes moving the X-ray source and the X-ray detector, determining a strip-shaped detection region within the detection area, by expanding an extent of the X-ray recording compared with a further different X-ray recording, and acquiring and recording each respective successive recording portion, of the successive recording portions, using the determined detection region and the X-ray source. Finally, the method includes generating an assembled X-ray recording of the examination region from the successive recording portions recorded.Type: GrantFiled: March 29, 2021Date of Patent: June 6, 2023Assignee: SIEMENS HEALTHCARE GMBHInventors: Magdalena Herbst, Ludwig Ritschl, Marc Cottiati, Christoph Luckner, Qi Hu, Marcel Beister, Fabian Wloka

Publication number: 20220096033Abstract: A method is for reconstructing an image from recording data. In an embodiment, the method includes providing or measuring recording parameters with which the recording data was created; generating a preprocessing filter for the recording data based on the recording parameters; prefiltering the recording data with the preprocessing filter, to create prefiltered recording data; and reconstructing the image from the prefiltered recording data. A prefilter-generating unit, an apparatus corresponding to the method, a control facility and an image-taking system are also disclosed.Type: ApplicationFiled: September 22, 2021Publication date: March 31, 2022Applicant: Siemens Healthcare GmbHInventors: Marcel BEISTER, Ludwig RITSCHL, Steffen KAPPLER

Patent number: 11116468Abstract: A method for controlling an X-ray projection imaging device includes applying preferences for a serial radiography image acquisition to the X-ray projection imaging device. The method further includes executing the serial radiography image acquisition with the X-ray projection imaging device; recording data frames at different times during the serial radiography image acquisition; applying a trigger signal to the X-ray projection imaging device during the serial radiography image acquisition; and generating a snapshot image from a subset of the data frames, wherein the subset is chosen from the data frames recorded based on the trigger signal. A related system, a related control unit and a related X-ray projection imaging system are also disclosed.Type: GrantFiled: October 16, 2019Date of Patent: September 14, 2021Assignee: SIEMENS HEALTHCARE GMBHInventors: Marcel Beister, Ruediger Bock, Bernhard Geiger, Sandra Jedinger
