CT 扫描仪与核磁共振成像仪的医学成像

实现实时高分辨率图像处理,实现更高的集成度、灵活性和可靠性

概述

Magnetic resonance imaging (MRI) and computed tomography (CT) machines are large highly synchronous machines that require significant computational capabilities across their various subsystems.  The integration with Xilinx Zynq UltraScale+ SoC provides a platform for the high-speed SiC inverter control required in the gradient amplifiers, RF waveform synthesis required in RF transmit chain, and the massively parallel ADC interfaces and signal process required on the RF receive.  The coupling of an ARM processing system in the each of the sub-systems provides a platform for low-latency critical communications, maintenance, and co-processing functions to be implemented in a rich OS environment. 

对于图像重建的卸载/加速(2D FFT 用于核磁共振,而后投影则用于 CT)以及机器学习图像分析的集成,Xilinx Versal AI 内核系列等新一代 7nm ACAP 器件具有很好的前景。
