    Abstract: A method for producing a scattered radiation grid for x-ray radiation by stacking strips and an associated scattered radiation grid are provided. The strips are cut out of a laminate that includes a first layer, a second layer, and a third layer. The first layer is formed from a first material that absorbs x-ray radiation, and the second layer is formed from a second material that is permeable to the x-ray radiation. A second material that is highly permeable to the x-ray radiation and reduces the attenuation of the scattered radiate on grid may be used.

    Abstract: An arrangement for navigating an endoscopic capsule includes an external first magnetic field with a first magnetic flux density for moving the endoscopic capsule. The arrangement also includes at least one sensor coil pair outside of the endoscopic capsule for determining a position and/or orientation of the endoscopic capsule. The at least one sensor coil par includes a first sensor coil and a second sensor coil. The first sensor coil and the second sensor coil are electrically connected to one another and arranged at locations with the same first magnetic flux density.

    Abstract: An amplifier and a coil are electrically connected to an amplifier in a coil system. A current controller is provided for adjustment of the current which is supplied from the amplifier to the coil. The current controller adjusts the current such that, at least on average, a predetermined power loss is converted to heat in the coil.
