Patent number: 10932740Abstract: A method for optimizing an X-ray imaging system during a mammographic examination. In order to provide an optimization of the X-ray imaging a breast is compressed between a support plate and a compression plate. A force-height curve is then acquired during the compression. An elasticity value of the breast is determined based on the force-height curve. A parameter of the X-ray imaging system is optimized based on the determined elasticity value.Type: GrantFiled: October 21, 2014Date of Patent: March 2, 2021Assignee: KONINKLIJKE PHILIPS N.V.Inventor: Hanno Heyke Homann

Patent number: 10448911Abstract: Medical images are acquired in a tomosynthesis process. Processed 3D volume data representing a target acquired from scanning may be viewed from a set of forward projection directions, in which one or more forward projections through the processed 3D volume data is oblique relative to a central acquisition direction of the scanning process. The first set of forward projections is then displayed as a set of synthetic mammograms. Therefore, a medical practitioner can more easily identify abnormalities within a target volume, because the relative displacement of abnormalities at different depths in the target volume will change at different rates dependent on the viewing angle as the viewing position is moved around the target.Type: GrantFiled: October 30, 2014Date of Patent: October 22, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Klaus Erhard, Hanno Heyke Homann, Jonas Rikard Rehn

Patent number: 10251594Abstract: Minimally-invasive spinal inventions are often performed using fluoroscopic imaging methods, which can give a real-time impression of the location of a surgical instrument, at the expense of a small field of view. When operating on a spinal column, a small field of view can be a problem, because a medical professional is left with no reference vertebra in the fluoroscopy image, from which to identify a vertebra, which is the subject of the intervention. Identifying contiguous vertebrae is difficult because such contiguous vertebrae are similar in shape. However, characteristic features, which differentiate one vertebra from other vertebra, and which are visible in the fluoroscopic view, may be used to provide a reference.Type: GrantFiled: January 7, 2016Date of Patent: April 9, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Tobias Klinder, Eberhard Sebastian Hansis, Michael Grass, Dirk Schaefer, Hanno Heyke Homann, Christian Haase

Patent number: 10114090Abstract: A magnetic resonance imaging system acquires magnetic resonance data from a target volume in a subject. The magnetic resonance imaging system includes multiple excitation sources for generating a slice-selective or slab-selective spatial radio frequency (RF) excitation magnetic field targeting slice/slab spatial variations in the target volume, and a controller coupled to the excitation sources. The controller is adapted for: determining a power level required by the excitation sources for generating the slice-selective/or slab-selective spatial RF excitation magnetic field, decomposing the slice-selective or slab-selective spatial RF excitation magnetic field into respective RF excitation constituents of the excitation sources, controlling each of the excitation sources to simultaneously generate the respective RF excitation constituent, using the determined power level for acquiring the magnetic resonance data.Type: GrantFiled: October 1, 2013Date of Patent: October 30, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Ulrich Katscher, Hanno Heyke Homann, Peter Boernert

Patent number: 9901319Abstract: The invention relates to peripheral equalization during a mammography X-ray examination. High contrast tissue pixel values are removed from the background estimate by finding the minimum intensity values of the pixel located in the neighborhood, which have approximately the same distance to the skin line. Thus, high attenuating pixel values may be removed from the estimate and replaced by lower attenuating tissue pixel values. After a minimum filtration, a conventional peripheral equalization is performed. This may result in less overshoots and intensity values for higher attenuating structures in the peripheral region may become more consistent with intensity values for higher attenuating structures in the fully compressed region.Type: GrantFiled: November 16, 2015Date of Patent: February 27, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Frank Bergner, Hanno Heyke Homann, André Goossen, Hanns-Ingo Maack

Patent number: 9836872Abstract: A method and related apparatus (VS) for synthetic projection images, in particular synthetic 2D mammograms (S) formed from a 3D image volume T made up of slices (SL). It is proposed to compute a forward projection (FP) using a weighted average function that is implemented by a filter (FL). The filter function (FL) is configured such that that voxels in a slice with maximum sharpness are assigned highest weights thereby avoiding blurring by averaging with structurally less relevant slices.Type: GrantFiled: June 26, 2014Date of Patent: December 5, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Klaus Erhard, Hanno Heyke Homann, Jonas Rikard Rehn
