摘要： An image acquisition system (100, 500, 600, 700). The image acquisition system may include at least one processor (110, 502-2, 610, 710) configured to control: a transmitter (112, 612) to form packets for transmission over a high-data-rate (HDR) wireless communication link (HDR-WCL) (124, 624), an image acquisition device (120, 631) to acquire image data and form HDR data, and a scheduler (114, 614) to acquire control information for controlling at least one function of the image acquisition system during the image acquisition, determine a restricted packet size for the packets of the HDR-WCL in accordance with at least deterministic timing requirements of the system, and determine a schedule for transmitting the control information in a corresponding packet of the packets in accordance with the deterministic timing requirements of the image acquisition system and the restricted packet size.

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 system and method synchronizes a digitizer clock of a Magnetic Resonance Imaging (MRI) device with a system clock of an imaging device. In a first method, an original reference signal is split into first and second reference signals in which the second reference signal is phase shifted to generate an orthogonal reference signal. A reliability of image data may be determined based upon a product between the first reference signal and the orthogonal reference signal. In a second method, a reference signal is transmitted from the imaging device to the MRI device and a return signal is received from the MRI device to the imaging device. A discrepancy between the digitizer clock and the system clock may be determined based upon the return signal which includes a variable time delay.

摘要： A magnetic resonance (MR) coil array (26, 28) connected by way of a single transmission line (46, 48) is provided. The MR coil array (26, 28) includes a coil element (34) and a corresponding coil element circuit (32). The coil element circuit (32) includes at least one active component (40) powered by a power signal carried on the coaxial transmission line (46, 48). The voltage of the power signal varies between first and second direct current (DC) voltages of the same polarity. The coil element circuit (32) further includes a tune/detune circuit (42) connected to the coaxial transmission line (46, 48). The tune/detune circuit (42) tunes or detunes the coil element (34) based on the first and second DC voltages. An MR system (10) using the MR coil array (26, 28) and a method (10) for tuning or detuning the MR coil (26, 28) are also provided. Accordingly, a single coaxial cable between the MR system and the coil element is sufficient for conveying MR data, a power signal for the preamplifier and a detuning signal. Moreover, the preamplifier can be powered irrespective of the coil element being in the tuned or in the detuned state.
