Publication number: 20240133989Abstract: A magnetic resonance (MR) system includes an MR receive channel (20) including: an MR coil element (22) configured to receive MR signals in an MR frequency band; an electronic signal processing chain (24) configured to process the MR signals received by the MR coil element to produce processed MR signals, wherein the electronic signal processing chain includes an equalization filter (26); and a signal injector (8, 16, 28, 38, 38D) configured to input a reference radio frequency (RF) signal in the MR frequency band to the signal processing chain, wherein the signal processing chain processes the reference RF signal to generate a processed reference RF signal. Equalizer electronics (30) are configured to adjust the equalization filter based at least on the processed reference RF signal such that the MR receive channel has a flat frequency response over the MR frequency band.Type: ApplicationFiled: February 23, 2022Publication date: April 25, 2024Inventors: Rodrigo Calderon Rico, Alton Keel, Tracy Allyn Wynn, Arne Reykowski, Scott Bradley King

Patent number: 11454685Abstract: A wireless magnetic resonance (MR) signal receiving system comprises a wireless MR coil (20) and a base station (50). The wireless MR coil includes coil elements (22) tuned to receive an MR signal, and electronic modules (24) each including a transceiver (30) and a digital processor (32). Each electronic module is operatively connected to receive an MR signal from at least one coil element. The base station includes a base station transceiver (52) configured to wirelessly communicate with the transceivers of the electronic modules of the wireless MR coil, and a base station digital processor (54). The electronic modules form a configurable mesh network (60) to wirelessly transmit the MR signals received by the electronic modules to the base station. The base station digital processor is programmed to operate the base station transceiver to receive the MR signals wirelessly transmitted to the base station by the configurable mesh network.Type: GrantFiled: November 27, 2018Date of Patent: September 27, 2022Assignee: Koninklijke Philips N.V.Inventors: Paul Franz Redder, Arne Reykowski, Rodrigo Calderon Rico

Patent number: 11438135Abstract: A method for communicating magnetic resonance imaging (MRI) information wirelessly includes detecting an MRI system emission sequence, and identifying at least one parameter of the sequence. The at least one parameter identified is cross-correlated. A first initial condition for a first chaotic coded sequence and a second initial condition for a second chaotic coded sequence are determined based on the at least one parameter. The method further includes obtaining, from a modulation symbol mapped to MRI information generated at a local coil responsive to the sequence, a real component of the symbol and an imaginary component of the symbol. The real component of the symbol is encrypted based on the first initial condition, and the imaginary component of the symbol is encrypted based on the second initial condition. The encrypted real component and imaginary component of the symbol are wirelessly transmitted.Type: GrantFiled: January 15, 2018Date of Patent: September 6, 2022Assignee: Koninklijke Philips N.V.Inventors: Rodrigo Calderon Rico, Timothy Ortiz, George Randall Duensing

Patent number: 11320501Abstract: A clocked electronic device, such as a wireless magnetic resonance (MR) receive coil (20), comprises a wireless receiver or transceiver (30) configured to receive a propagation-delayed wireless clock synchronization signal (54) comprising first and second propagation-delayed carrier signals at respective first and second carrier frequencies separated by a frequency difference, a clock (60) comprising a local oscillator (62) driving a digital counter (64), and at least one electronic signal processing component (66) configured to perform clock synchronization. This includes determining a wrap count (k) from a phase difference (?1) between phases of the first and second propagation-delayed carrier signals, unwrapping a wrapped phase (?2,wrapped) of the propagation-delayed wireless clock synchronization signal using the wrap count to generate an unwrapped phase (?2,wrapped), and synchronizing the clock using the unwrapped phase.Type: GrantFiled: January 30, 2019Date of Patent: May 3, 2022Assignee: Koninklijke Philips N.V.Inventors: Arne Reykowski, Paul Franz Redder, Rodrigo Calderon Rico

Patent number: 11277808Abstract: A base station operating with a system clock includes a transmitter, a receiver, a phase error detector and a controller. The transmitter sends a first RF signal modulated onto a first RF carrier having a first phase over a first channel having a first variable phase delay to a mobile station. The mobile station recovers the first RF carrier, generates a second RF carrier, and synchronizes a local clock using the recovered first RF carrier and/or the second RF carrier. The receiver receives a second RF signal modulated onto the second RF carrier having a second phase over a second channel having a second variable phase delay. The phase error detector determines a phase error signal based on the first and second phases, and the controller generates a control signal based on the phase error signal. The control signal is applied to first and second inverse channel models.Type: GrantFiled: January 8, 2019Date of Patent: March 15, 2022Assignee: Koninklijke Philips N.V.Inventors: Arne Reykowski, Paul Franz Redder, Rodrigo Calderon Rico
