  • Publication number: 20160302746
    Abstract: The present invention relates medical imaging, more particularly to the display of medical images 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.

  • Publication number: 20160235379
    Abstract: There is a method and a corresponding system for optimizing X-ray imaging during a mammographic examination. In order to provide an optimization of X-ray imaging in a first step (SOI) a breast (7) is compressed between a support plate (5) and a compression plate (3). In a next step (S03), a force-height curve (13) is acquired during compression. Then, in a further step (S05) an elasticity value of the breast (7) is determined radiation-free based on the force-height curve (13). In a further step (S07), a parameter of an X-ray imaging system is optimized based on the determined glandularity (g). As the glandularity (g) of a breast may influence the attenuation of X-rays, the personalized setting of the parameters of the X-ray imaging system may greatly enhance the image quality.

  • Publication number: 20160140749
    Abstract: 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.

  • Publication number: 20160071293
    Abstract: A method for processing image data of an X-ray device (10) comprises the steps of: receiving a plurality of two-dimensional projection images (32) from an object of interest (22), wherein the projection images have been acquired by transmitting X-rays (20) through the object of interest (20) with respect to different view angles; generating a three- dimensional raw image volume (36) from the plurality of two-dimensional projection images (32) with respect to a coordinate grid (50) adapted to the geometry of the transmitted X-rays (20); and generating a deconvolved three-dimensional image (40) by applying a two- dimensional deconvolution to slices (52) of the three-dimensional raw image volume (36), which slices (32) are adapted to the coordinate grid (50).

  • Patent number: 9262825
    Abstract: The present invention discloses a method for reconstructing an image obtained from kVp switched imaging of a body by acquiring a plurality of images at a first kVp defining a first image scan and a plurality of images at a second kVp defining a second image scan, wherein the plurality of images at the first kVp are acquired interleaved with the plurality of images of the second image scan and by reconstructing an image from the first and second image scan, comprising determining at least one gradient location for at least two images in the first and second image scans, determining divergent gradient locations in respect of a same part of the body for said at least two images in the first and second image scans, tagging each divergent gradient location as an under sampling artifact, generating the reconstructed image from the at least two images in the first and second image scans by correcting for each tagged under sampling artifact.

  • Patent number: 9229074
    Abstract: A method and system for calculating a local specific energy absorption rate (SAR) is based on an electric parameter and the mass density of a segmented geometry of an object and a magnetic field vector distribution of a radio frequency (RF) antenna. The values of the electric parameter and the mass density are pre-determined values, while the magnetic field vector distribution is estimated by a magnetic field mapping method based on a magnetic resonance (MR) scan, such as a B1 mapping method.

  • Publication number: 20150260808
    Abstract: The present invention relates to a magnetic resonance imaging MRI system (100) for acquiring magnetic resonance data from a target volume in a subject (101), the magnetic resonance imaging system (100) comprising: a plurality of excitation means (201) for generating a slice-/or slab-selective spatial radio frequency RF excitation magnetic field targeting slice/slab spatial variations in the target volume, and a controller (219) coupled to the plurality of excitation means (201), wherein the controller (219) is adapted for: determining a power level required by the plurality of excitation means (201) for generating the slice-/or slab-selective spatial RF excitation magnetic field, decomposing the slice-/or slab-selective spatial RF excitation magnetic field into respective RF excitation constituents of the plurality of excitation means (201), controlling each of the plurality of excitation means (201) to simultaneously generate the respective RF excitation constituent, using the determined power level for acqu

  • Publication number: 20140210472
    Abstract: Embodiments of the invention relate to a magnetic resonance imaging system (300) for acquiring magnetic resonance data (358) from a subject (318) that may comprise an electrically conductive object (e.g. an implant or a medical device). The magnetic resonance imaging system comprises a radio-frequency transmitter (314) for generating a radio-frequency transmit field for acquiring the magnetic resonance data using a radio-frequency antenna (310). The radio-frequency transmitter has multiple transmit channels. The radio-frequency antenna comprises multiple antenna elements (312) each adapted to connect to an antenna element. According to an embodiment of the invention, the amplitude and phase values of the RF transmit field of each of the transmit channels are selected such that the magnetic field generated by the RF antenna is minimized at the location of the electrically conductive object, thereby reducing RF heating of the object.

  • Publication number: 20120262174
    Abstract: A method for calculating a local specific energy absorption rate (SAR) on basis of an electric parameter and the mass density of a segmented geometry of an object and a magnetic field vector distribution of a radio frequency (RF) antenna. The values of the electric parameter and the mass density are pre-determined values, while the magnetic field vector distribution is estimated by a magnetic field mapping method based on a magnetic resonance (MR) scan. The magnetic field mapping method based on a magnetic resonance scan can be a Bi mapping method. The invention also relates to a magnetic resonance system by means of which SAR calculation can be done in a relatively short period of time. The invention also relates to a computer program comprising instructions for calculating a local specific energy absorption rate (SAR) according to the above mentioned method.
