Development of a Parallel Radiofrequency Transmission Subsystem for MRI at 3 Tesla

Per Vices Corporation是一家总部位于多伦多的公司，生产高质量的软件定义无线电（SDR）设备。从历史上看，无线电由多个具有不同信号处理功能的电子元件组成；SDR现在可以使这些硬件的大部分被简化，并使用个人计算机与嵌入在一个电子设备中的实时计算机进行通信。广泛的软件现在被广泛用于许多商业应用，例如电信和安全。Per Vices有意将其设备的市场扩展到医疗保健领域。特别是，射频传输是临床磁共振成像（MRI）系统的关键要素。PerVices希望将他们在SDR方面的专业知识与MRI物理学家兼工程师Simon Graham博士的专业知识结合起来，使PerVices的技术能够在这方面得到应用。Per Vices和Graham博士将进行初步的研究和开发，以验证和验证该公司的“Crimson SDR”设备在临床级MRI系统上促进了一种称为并行射频传输（PTX）的新兴技术。PTX在提高临床MRI能力方面具有巨大的潜力，但支持基础设施尚未广泛可用。如果成功的话，Crimson SDR可能会成为一个新的PTX硬件产品的核心组件，可以卖给MRI研究社区，并最终卖给跨国MRI系统供应商。

Per Vices Corporation is a Toronto-based company that makes high quality software defined radio (SDR)devices. Historically, radios consisted of multiple electronic components with different signal processingfunctions; SDR now enables much of this hardware to be streamlined and performed using a personalcomputer, in communication with a real-time computer embedded in one electronic device. Extensive softwareis now widely available to operate SDRs for many commercial applications, for example intelecommunications and in security.Per Vices is interested in expanding the market for its devices into the healthcare sector. In particular,radiofrequency transmission is a critical element of clinical magnetic resonance imaging (MRI) systems. PerVices hopes to combine their expertise in SDR with that of Dr. Simon Graham, an MRI physicist and engineer,to enable use of Per Vices technology in this context. Per Vices and Dr. Graham will undertake initial researchand development to verify and validate that the company's "Crimson SDR" device facilitates an emergingtechnique called parallel radiofrequency transmission (PTX) on a clinical-grade MRI system. PTX hassubstantial potential to improve clinical MRI capabilities, but the enabling infrastructure is not widelyavailable. If successful, the Crimson SDR could become the central component of a new PTX hardwareproduct that could be sold to the research MRI community, and ultimately to multi-national MRI systemvendors.
