Problems solved by technology

Correspondingly, it is difficult or nearly impossible to communicate with the MRI system for a wireless type RF coil that lacks these proprietary methods (eg, a wireless type RF coil manufactured by a different manufacturer than the MRI system). Clock synchronization
Accordingly, users of existing MRI systems can only choose from conventional wireless type coils manufactured by the same manufacturer or a licensed manufacturer
Furthermore, since MRI systems typically store data acquired during diagnostic procedures on local memory, this data may not be available without the MRI system and corresponding data access or usage charges

Embodiment Construction

[0016] The following is a description of exemplary embodiments which, when considered in conjunction with the following drawings, will demonstrate the above-noted and other features and advantages. In the description that follows, illustrative details, such as architectures, interfaces, technologies, element attributes, etc., are set forth for purposes of explanation rather than limitation. However, it will be apparent to a person skilled in the art that other embodiments that depart from these details should still be understood to fall within the scope of the appended claims. Moreover, for the purpose of clarity, detailed descriptions of well-known devices, circuits, tools, techniques and methods are omitted so as not to obscure the description of the present system. It should be expressly understood that the drawings are included for illustration purposes only and do not represent the full scope of the system. In the drawings, similar reference numbers in different drawings...

Abstract

A system for controlling a radio frequency (RF) coil arrangement (102, 202, 302, 500) of the wireless type for a magnetic resonance (MR) system, the system comprising a processor for: acquiring Transmitting radio frequency (RF) signals from a plurality of coils of an array of transducers, said transmitting radio frequency (RF) signals including an indication of a local clock signal indicating the time at which the (RF) signals were acquired; acquiring a plurality of field probes from an array of magnetic field probes magnetic field strength information including an indication of a local clock signal indicating the time at which the magnetic field strength information was collected; The transmitted RF signals of the plurality of coils and the collected magnetic field intensity information form k-space information.

Description

technical field [0001] The present system relates to a k-space state machine for magnetic resonance (MR) imaging (MRI) systems and magnetic resonance spectroscopy (MRS) systems, and more specifically, to a k-space state machine with a mobile k-space state for MRI systems and MRS systems A radio frequency (RF) coil for a machine and a method of operation thereof. Background technique [0002] MRI is an imaging technique that uses frequency and phase encoding of protons for image reconstruction. Recently, wireless type receiving coils, for example, radio frequency (RF) coils (may also be called wireless type or receive only type RF coils, etc.) have become available. These wireless type RF coils rely on precise synchronization of their local clocks with the system clock of the MRI system (e.g., typically on the order of picoseconds, which would result in a complex system of wireless clock delivery and recovery) to properly time signal acquisition. Timing with the correspondi...
