Magnetic resonance scanner Siemens MAGNETOM Prisma 3T
Spatial information is encoded by a whole-body gradient system producing gradients of up to 40 milliteslas per meter along each of the three Cartesian axes within a minimal ramp time of 200 microseconds. The resonance frequency in imaging experiments with hydrogen is 123.2 megahertz. The scanner was equipped as the first of its kind with a whole-body coil. In addition, various head coils are used to investigate the human brain. In pulsed mode, the amplifiers generate up to 35 and 8 kilowatts for the body coil and the transmit head coils, respectively. For receive, eight parallel channels are available with an analog bandwidth of 1 megahertz. A broad-banded second radiofrequency channel is available for magnetic resonance experiments with nuclei other than hydrogen.
