  • Publication number: 20190279746
    Abstract: A system is used to control operation of a user device. An association between a medical condition and one or more decision trees is maintained. Each decision tree includes nodes organised in a tree structure originating at a root node and terminating at leaf nodes via branch nodes. The nodes are linked to each other via outputs and each output causes the system to differently control operation of the user device. Responsive to receiving medical information associated with the patient, using the association, a decision tree is identified. For the root node of the identified decision tree: a first node is selected, responsive to receiving data indicative of a first output regarding the root node; the user device is caused to retrieve medical information from one or more data sources based on the first node; and the retrieved medical information is caused to be displayed on the user device.

  • Publication number: 20190277931
    Abstract: In a method and apparatus for recording magnetic resonance data for determining at least one parameter map describing a material parameter in the scanning region, the scanning area having a number of slices, a slice-specific preparation pulse is used, wherein magnetic resonance data are scanned after different waiting times following the preparation pulse. Magnetic resonance data of different waiting times are acquired from at least two slices, by determining an overall pulse by overlaying the slice-specific preparation pulses for the individual slices, and then activating the overall pulse to read out the magnetic resonance data of the slices with a readout sequence after the respective waiting times.

  • Publication number: 20190277932
    Abstract: In a method and apparatus for recording a magnetic resonance data record in a capture region of an examination object, the capture region being composed of multiple slices, an imaging technique is implemented that uses reference data in the reconstruction of magnetic resonance images, wherein, for all the slices, at least two partial data records are recorded with respectively different contrasts. For thus purpose, a first partial data record is recorded without a preparation pulse and a second partial data record is recorded with a preparation pulse, in particular an inversion pulse. The reference data for at least one first slice for the first partial data record are recorded during a waiting time after the preparation pulse for at least one other, second slice, from which reference data relating to the second partial data record are to be recorded.

  • Publication number: 20190277930
    Abstract: In a method and computer for creating a pulse sequence for controlling a magnetic resonance (MR) tomography system to generate image data, raw MR data are acquired by exciting different transverse magnetizations in a number of sub-volumes of the subject, with a sequence of pulse iterations being executed that each prepare, excite and read out sub-volumes. The pulse iterations are designed so that a readout occurs when the pulse sequence is applied between a preparation of two spatially directly adjacent sub-volumes.

  • Publication number: 20190274576
    Abstract: In a method and apparatus for acquiring and reconstructing a four-dimensional dynamic magnetic resonance (MR) image data record, MR data are continuously acquired by radial scanning of an examination region along radial k-space lines, and a dynamic region of the examination region, in which said dynamic procedure is relevant, is determined, as well as a non-dynamic region, which is not relevant to the dynamic procedure. Static image data are reconstructed from all of the acquired MR data, and image data therein originating from the non-dynamic region are marked and are then not used for reconstructing a dynamic image data record for the dynamic region.

  • Patent number: 10409235
    Abstract: The process of creating a 3D printer ready model of patient specific anatomy is automated. Instead of manual manipulation of the 3D mesh from imaging to create the 3D printer ready model, an automated manipulation is provided. The segmentation may be automated as well. In one approach, a transform between a predetermined mesh of anatomy and patient specific 3D mesh is calculated. The predetermined mesh has a corresponding 3D printer ready model. By applying the transform to the 3D printer ready model, the 3D printer ready model is altered to become specific to the patient. In addition, target manipulation that alters semantic parts of the anatomical structure may be included in 3D printing.

  • Patent number: 10410093
    Abstract: A method of classifying signals using non-linear sparse representations includes learning a plurality of non-linear dictionaries based on a plurality of training signals, each respective nonlinear dictionary corresponding to one of a plurality of class labels. A non-linear sparse coding process is performed on a test signal for each of the plurality of non-linear dictionaries, thereby associating each of the plurality of non-linear dictionaries with a distinct sparse coding of the test signal. For each respective non-linear dictionary included in the plurality of non-linear dictionaries, a reconstruction error is measured using the test signal and the distinct sparse coding corresponding to the respective non-linear dictionary. A particular nonlinear dictionary corresponding to a smallest value for the reconstruction error among the plurality of non-linear dictionaries is identified and a class label corresponding to the particular non-linear dictionary is assigned to the test signal.

  • Publication number: 20190271751
    Abstract: A method for determining a change over time in a biomarker in a region to be examined of a patient is provided. The change is determined from magnetic resonance data using a magnetic resonance measuring system with sequences and protocols for measuring the biomarkers by functional resting state connectivity by rsfMRI, perfusion values, magnetic resonance spectra of voxels, or morphometry of organs. A control unit has programs which evaluates the biomarker and a data memory which stores the results of the evaluation and additional data. During a first examination, a quantity result of the biomarkers is determined and stored in the data memory. During a follow-up examination, at least one previous item of the result and additional data from the first examination stored in the data memory are used for determining a quantitative change in the biomarker.

  • Patent number: 10402535
    Abstract: A method and system for personalized computation of tissue ablation extent based on medical images of a patient is disclosed. A patient-specific anatomical model of the liver and liver vessels is estimated from medical image data of a patient. Blood flow in the liver and liver vessels is simulated. An ablation simulation is performed that uses a bio-heat model to simulate heat diffusion due to an ablation based on the simulated blood flow and a cellular necrosis model to simulate cellular necrosis in the liver based on the simulated heat diffusion. Personalized tissue parameters of the bio-heat model and the cellular necrosis model are estimated based on observed results of a preliminary ablation procedure. Planning of the ablation procedure is then performed using the personalized bio-heat equation and the cellular necrosis model. The model can be subsequently refined as more ablation observations are obtained.

  • Patent number: 10398391
    Abstract: A tomography installation is configured to carry out a first scan along a first helix-segment-shaped trajectory section and to carry out a second scan along a second helix-segment-shaped trajectory section. A first data set is obtained during the first scan, and a second data set is obtained during the second scan. Taken by themselves in each case, both the first data set and the second data set are too incomplete for a reconstruction of a volume image without a partial revolution artifact. From the two data sets, a fused three- or four-dimensional data set is generated that is sufficiently complete for a reconstruction of a volume image without a partial revolution artifact.
