摘要： A dongle, and an apparatus to charge and replace components of the dongle are described. The dongle includes: a battery configured to provide direct current (DC) power to a device to which the dongle is electrically and mechanically connected, the battery being adapted to be removed, and replaced by another battery; and a heat sink configured to dissipate heat generated by the battery, the heat sink being adapted to be removed, and replaced by another heat sink.

摘要： A magnetic resonance imaging (MRI) system (100, 400, 500) includes a wireless RF station (20, 320, 420, 520, 620) which is associated with one or more RF coils which sense the magnetic resonance (MR) signal emitted from a subject under MRI examination. The wireless RF station communicates digital data representing the sensed MR signal to an MRI controller (124) for further processing, which may include display. An internal clock (2202, 3202) in the wireless RF station is precisely synchronized with the MRI controller clock (108, 2101, 3101), with carrier phase synchronization and code phase tracking of a predefined code sequence such as a pseudo random number (PRN) sequence.

摘要： A magnetic resonance (MR) system, including at least one wireless radio-frequency (RF) coil comprising antennas for receiving induced MR signals and an antenna array comprising transmission and reception antennas; a base transmitter system (BTS) having an antenna array comprising a plurality of transmission and reception antennas configured to communicate with the RF coil using a selected spatial diversity (SD) method; and at least one controller to control the BTS and the RF coil to determine a number of transmission and/or reception antennas available, couple the transmission and reception antennas to form corresponding antenna pairings, and determine signal characteristic information (SCI) of the antenna pairings,select an SD transmission method based upon the determined number of antennas and the determined SCI for communication between the BTS and the RF coil, and establish a communication channel between the BTS and the RF coil in accordance with the selected SD transmission method.
