Abstract: A medical imaging system includes a stationary gantry and a rotating gantry that rotates around an examination region about a z-axis. An air bearing rotatably couples the rotating gantry to the stationary gantry. A radiation source is affixed to the rotating gantry and rotates with the rotating gantry and emits radiation that traverses the examination region. A detector array is affixed to the rotating gantry on an opposite side of the examination region with respect to the radiation source and detects radiation traversing the examination region. A dynamic z-axis imbalance determination system determines an imbalance of the rotating gantry in the z-axis direction directly from the air bearing, and the determined imbalance is used to position a balance mass affixed to the rotating gantry in the z-axis direction, thereby balancing the rotating gantry along the z-axis.

Abstract: The invention relates to a detection values processing apparatus. Energy-dependent detection values are provided, which are indicative of polychromatic radiation (4) after having traversed an examination zone (5). The radiation is filtered by a filter (15) which comprises K-edge filter material. A component decomposition technique is applied to the detection values for determining K-edge attenuation values being first component attenuation values, which are indicative of an attenuation caused by the K-edge filter material, and additional component attenuation values, which are indicative of an attenuation caused by additional components of the examination zone, wherein an image of the examination zone is reconstructed from the additional component attenuation values. An image can therefore be reconstructed, which is not adversely affected by the filter, because the K-edge attenuation values are not used for reconstructing the image. This can improve the quality of the reconstructed image.

Abstract: The invention relates to a multi-channel (e.g. quadrature) MRI transmit system in which RF power amplifiers having different power capabilities are used in different transmit channels. This results in reduced system costs, due to the avoidance of an unused excess of RF power capability when the power demand for obtaining a homogeneous B1-field (RF shimming) is asymmetric and the asymmetry is qualitatively the same for different imaging applications. The multi-channel transmit unit may also comprise a commutator which enables to selectively connect each RF power amplifier to each drive port of transmit coil arrangement (e.g. a birdcage coil).
