摘要： The invention relates to a parallel magnetic resonance imaging method, in which core magnetization is excited in the examination volume of an MR device by generating at least one HF pulse. Two or more MR signals are then recorded in parallel from the examination volume via two or more receiving channels (R, S) of the MR device using an HF coil arrangement (9), which comprises a number of coil elements (15, 16) which is greater than the number of receiving channels (R, S), wherein the respective MR signal on each receiving channel (R, S) is formed by weighted superimposition of coil signals (A, B, C, D, E) of the individual coil elements (15, 16). Finally, according to the invention, an MR image is reconstructed from the recorded MR signals, the MR signals being combined with one another taking into account effective spatial sensitivity profiles associated with the individual receiving channels (R, S).

摘要： The invention relates to a color-controlled illumination device (1) with a number of light emitters, for example LEDs (L1, L2, L3, L4), of different primary colors. Photosensors (D1, D2, D3) consisting of a photodiode (20) covered with different dielectric filter layers (21) measure the light output of the light emitters (L1, L2, L3, L4) with distinct oscillating sensitivity curves that extend over the whole relevant spectral range. In a control unit (14), the actual color point of the illumination device (1) is calculated and the emissions of the light emitters (L1, L2, L3, L4) are individually adapted in order to match a target color point ((X,Y,Z) target ) given with e.g. CIE tri-stimulus values.

摘要： The use of standard coaxial cables for, e.g. connecting optional receive MR coils to MR-scanners has the problem that parasitic cable resonances may occur, which may cause RF burns to a patient. According to the present invention, the cable is divided into a huge number of small pieces. Each conductor in the small pieces is connected to the respective conductor in another small piece via a series capacitor. Due to this, e.g. at MR frequency, the cable according to the present invention is completely off resonant, such that no parasitic resonance may occur.
