摘要： A dielectric waveguide to transmit an electromagnetic signal, comprises: a first conductor region and a second conductor region. The first and second conductor regions extend along a longitudinal axis of the dielectric waveguide, wherein the first conductor region is formed from a first thermoplastic material and the second conductor region is formed from a second thermoplastic material. The first thermoplastic material has a higher effective permittivity than the second thermoplastic material.

摘要： Provided are computer-implemented methods and systems for classifying a medical image data set. In particular, a method is provided comprising the steps of receiving the medical image dataset of a patient, of providing a first classification stage configured to classify the medical image dataset as normal or not-normal, of providing a second classification stage different than the second classification stage and configured to classify the medical image dataset as normal or not-normal, and of subjecting the medical image dataset to the first classification stage to classify the medical image dataset as normal or not-normal. Further, the method comprises subjecting the medical image dataset to the second classification stage to classify the medical image dataset as normal or not-normal, if the medical image dataset is classified as normal in the first classification stage.

摘要： CMR imaging is synthesized, and/or machine learning for a CMR imaging task uses synthetic sample generation. A machine-learned model generates synthetic samples. For example, the machine-learned model generates the synthetic samples in response to input of values for two or more parameters from the group of electrocardiogram (ECG), an indication of image style, a number of slices, a pathology, a measure of heart function, sample image, and/or an indication of slice position relative to anatomy. The indication of image style may be in the form of a latent representation, which may be used as the only input or one of multiple inputs. These inputs provide for better control over generation of synthetic samples, providing for greater variance and breadth of samples then used to machine train for a CMR task.

摘要： An improved technique for recording of scan data is provided, which includes recording scan data from at least two slices of an examination object simultaneously by means of a magnetic resonance system. The technique includes selecting a desired simultaneous recording of scan data from at least two slices (S1, . . . , Sn), determining an artifact-preventing minimum RF pulse duration (dRF) for a desired recording, considering desired recording parameters (PA), and performing the desired recording using the determined minimum RF pulse duration.

摘要： A magnetic resonance tomography unit and a method for operating the magnetic resonance tomography unit are provided. The magnetic resonance tomography unit includes a plurality of magnetic field sensors arranged in an environment of the magnetic resonance tomography unit. The plurality of magnetic field sensors are configured to capture low-frequency magnetic fields in the environment of the magnetic resonance tomography unit and to transmit information about the magnetic fields to the controller via a signal connection. According to the method, fields for compensating the low-frequency magnetic fields are ascertained and output.

摘要： In a method for determining a type of characteristic eye movement of the eyes of a patient, the patient is provided with an optokinetic stimulus for the characteristic eye movement, a medical image of the brain of a patient also including the eyes of the patient is generated. An amount of a displacement of an optic nerve of the patient may be determined based on the medical image and a type of a characteristic eye movement may be determined based on the velocity of eye movement for the determined amount of displacement of the optic nerve. In a method for training an artificial intelligence based algorithm for determining an amount of a displacement of an optic nerve of a patient, the algorithm may be trained based on at least one medical image.

The MOSFET array has a drain connected to the second connection of the first resistor group and a source connected to the input of the body coil of the MRI system. After the output signal of the first opamp is input to the gate of the MOSFET array, the source outputs a constant preset current.
