Properties

1. Resource Description

   "The Siemens MAGNETOM 7T instrument is located in the Biomedical Research Building. The RF transmitter unit contains two independent digital RF transmitter channels, each capable of producing pulses with fully digital 1 MHz bandwidth, 32 bit frequency resolution, ≥16 bit phase resolution, and ≤50 ns time resolution. Eight solid-state RF power amplifiers are included, each capable of producing ≥1 kW over 270-305 MHz. If combined into one channel, these can produce ≥7 kW. This configuration also supports B1 shimming when transmit phases and amplitudes are controlled independently and delivered to the phased array head coil. A second RF amplifier is broadband capable (40-305 MHz) with a single 7 kW output. The AVANTO gradient coil set (2000V/625A) is capable of producing field gradients of ≥45 mT/m, with high slew rates ≥200 T/(m*s). TECHNICAL INFO: Field Strength/1H Frequency: 7 Tesla (T)/298 MHz Clear bore/Working bore: 90 cm/60 cm Gradient Strength/Slew Rate: ≥45 mT/m/ ≥200 T/(m*s) Receiver channels: 32 Length/Mass: 3.7m/30 tons (490 tons with iron shield)"
