Abstract: A medical examination installation has an MR system and an X-ray system that has an X-ray radiator with an X-ray tube and a solid-state X-ray image detector for producing X-ray exposures. The X-ray system has sensors for the acquisition of the location dependency of the stray field of the MR system in the three spatial axes, and coils for compensation of the stray field, and a computer that uses the output signal of the sensors to calculate a current for the coils which cause the stray field to be reduced in the region of the electron beams of the X-ray tube.

Abstract: In a method and apparatus for dynamically measuring the position, shape, size and intensity distribution of an effective focal spot of an x-ray tube, wherein at least one of these characteristics changes with respect to time, a detector array is provided that is composed of a number of detector elements, and a micro-hole collimator is disposed between the focal spot and the detector array at a distance closer to the focal spot than to the detector array. An x-ray beam emitted from the focal spot passes through an aperture in the micro-hole collimator, and produces a magnified projection of the focal spot on the detector array. The respective electrical signals from the detector elements of the detector array are sampled, and these sampled signals are combined to dynamically measure the position, shape, size and intensity distribution of the focal spot.

The device can be a ventilator or a neuroelectrical stimulation device. For faster and more efficient and more accurate respiratory aid the system contains a respiration detector, devised to pick up neuroelectrical signals from the living creature, identify respiration-related signals and send a control signal, related to the identified signals, to the device.

Abstract: In a method for sampling a received radio-frequency signal, in particular a radio-frequency signal from a receiving coil in a magnetic resonance apparatus, the received radio-frequency signal is down-mixed to a low-frequency baseband such as for image production. The radio-frequency signal from a receiving coil in a magnetic resonance apparatus is passed directly to a high clock rate analog/digital converter where it is converted, as a function of the clock, to a lower frequency, after which it is down-mixed by digital demodulation to a baseband at an even lower frequency.

Abstract: A metallic pulse generator housing has a tubular connector which receives a proximal lead end plug, the connector being located inside the housing and having a closed end within the housing and an open end welded or bonded to an opening in a wall of the housing. The connector is formed by a metallic barrel which is weldable or bondable to the metallic housing, the barrel being a structurally unitary tube member with a cavity containing electrical contacts for contacting contact surfaces on the lead end plug. At least one insulating substrate, on which the contacts are carried, is arranged in or on a region of a barrel wall which defines the cavity.

Abstract: Apparatus for dispensing beverage, such as beer, which forms a head, comprises a rotatable table on which a drinking vessel is supported, and a nozzle which is arranged to direct a stream of beverage against the side of the vessel as it rotates. This provides good control over the size of the head produced. Various parameters, such as the temperature of the beverage can be monitored during the dispense, and the apparatus controlled, by adjusting the rate of rotation of the table, the rate of dispense of the beverage, or the angle at which the beverage impacts the side of the vessel, so as to produce a desired amount of head on the dispensed beverage.

Abstract: In a method for image generation by magnetic resonance, a number of independent reception antennas having sensitivity profiles differing from one another are employed, and radio-frequency excitation pulses and gradient pulses are emitted into an imaging volume for generating location-coded magnetic resonance signals. The magnetic resonance signals are received with the reception antennas, and respective k-space data sets each having middle rows and outer rows are formed from the reception signals of the respective reception antennas. The middle k-space rows are more densely arranged than the outer k-space rows in the respective k-space data sets. An intermediate image is reconstructed from each k-space data set. The sensitivity profiles from the middle k-space data rows are determined and the intermediate images are combined dependent on the sensitivity profiles to form an overall image.

Abstract: In a method for producing an image of an examination subject by computed tomography using an x-ray source that moves around the examination subject for producing the image, a number of projections serving for the production of the image are registered during at least one revolution of the x-ray source around the examination subject. Motion artifacts of the image are at least reduced by identifying data representing a part of the image exhibiting a motion, and replacing that data with data complementary to the data exhibiting movement.

Abstract: A matrix array of recording heads, wherein each head is independent from another both in terms of its magnetic circuit and excitation conductors. Each individual head has a planar magnetic circuit and an helical coil wrapped around the lower part of the magnetic circuit. The matrix array is collectively fabricated using full thin film technology on non-magnetic substrates. Preferably, the heads are aligned in an oblique lattice with the write gaps aligned along rows and offset by a constant value along columns. Each individual head is connected to the control electronics through interconnects to the backside of the wafer, allowing independent control of the write parameters. The die forming the device is shaped on its edges and top surface to optimize head/medium positioning and minimize wear.

Abstract: Compressed wavelet transform coefficients are used to correct outputs of inertial sensors for gravitational deflections. The compressed wavelet transform coefficients comprise gravitational deflection data that is first converted to discrete wavelet coefficients by a discrete wavelet transform and that are then compressed to form the compressed wavelet transform coefficients. An inertial sensor signal relating to a first navigational parameter of a vehicle is generated. The compressed discrete wavelet coefficients are accessed from a memory based on a position of the vehicle. The accessed coefficients are decompressed, and an inverse discrete wavelet transform is performed on the decompressed coefficients to produce gravitational compensation data. The sensor signal is compensated based on the gravitational compensation data.
