AI Technical Summary

Problems solved by technology

However, these cables are undesirable because they attenuate the signal and are difficult to handle and store
Additionally, when damaged, these cables can heat and / or cause high patient specific absorption rate (SAR) levels
Although other types of links, such as fiber optic links, have been used to communicate with RF coils, these links require mechanical coupling which is undesirable from a handling and aesthetic standpoint
In addition, the mechanical coupling makes it difficult or impossible to correctly position the RF coil, such as a moving RF coil (MRF) for scanning

Abstract

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 a HDR) data packets transmitted over a wireless communication link (HDR‑WCL) (124, 624); control the image acquisition device (120, 631) to acquire image data and form HDR data; and control the scheduler to: acquire for use in the control information for controlling at least one function of said image acquisition system during said image acquisition, determining a restricted packet size for said data packets of said HDR-WCL based on at least deterministic timing requirements of said system, And a schedule for transmitting said control information in corresponding ones of said data packets is determined based on said deterministic timing requirements of said image acquisition system and said constrained data packet size.

Description

technical field [0001] The present system relates to communication systems for time- and data-intensive medical imaging systems, such as Magnetic Resonance (MR) Imaging (MRI) and Spectroscopy (MRS) systems, and more particularly to high data A rate and real-time operating system (RTOS) wireless communication system and method of operation thereof. Background technique [0002] In general, MRI systems have stringent requirements on the communication system, which affect the communication between the various components of the MRI system. For example, MRI communication systems must support both high data rate (HDR) operation and deterministic operation (eg, real-time operating system (RTOS)). Modern MRI systems typically employ radio frequency (RF) coils capable of acquiring MR data for multiple channels in parallel and thereafter digitizing the data to form digital content. Due to the size of the content, data rates greater than 1 GBPS are typically required to deliver the c...
