In China, Artificial Intelligence (AI) has deeply penetrated many industries, including medical care. This is motivated by the fact that 80 percent of medical data in China is imaging, which requires analysis and diagnosis based on the patient scans.
在中國,人工智能已經深入到包括醫療在內的許多行業。醫療數據中,80%都是影像數據,而影像數據需要根據患者掃描結果進行分析和診斷。
China faces two challenges with image processing: 1) there are not enough practitioners for human review to keep up with the growth of image volume, which currently expands by 30 percent per year; and 2) current computer-aided analysis lacks accuracy; manual review and subjective interpretation is inevitable.
中國在醫療影像處理方面面臨兩大挑戰:1.沒有足夠的從業人員進行人體檢查以滿足圖像量的增長,目前圖像量每年以30%的速度增長;2.目前的計算機輔助分析的準確性尚未獲得驗證;人工審查不可避免。
AI in Medical Imaging Science
醫療影像學人工智能
The application of AI inferencing in medical imaging is complicated, requiring powerful processing capabilities for such challenges as data diversification, deep analysis, and complicated labeling. Medical image analysis requires support of 3D?or even 4D?deep neural network (DNN) architectures, which rely heavily on platform memory during processing. GPUs are often unable to handle the tremendous number of workloads required to process 3D and 4D image data. Therefore, medical teams may reduce the pixels of 3D image data and split them into multiple small blocks for sequential recognition. The TensorFlow* deep learning framework used to train algorithms on imaging data can benefit from optimizations for Intel? Xeon? Scalable processors.
將人工智能應用于醫療影像推理是非常復雜的,需要強大的處理能力來應對數據多樣化、深度學習和復雜標記等挑戰。醫療影像分析需要支持3D甚至4D深度神經網絡(DNN)體系結構,在處理過程中嚴重依賴于平臺內存。GPU通常無法滿足處理3D和4D影像數據時所需的大量工作負載。因此,醫療團隊通常采用減少3D影像數據的像素,并將其分割成多個小的影像塊進行順序識別。用于訓練成像數據算法的TensorFlow*深度學習框架可以從英特爾至強可擴展處理器的優化中獲益。
The Intel Xeon Scalable processor family is well-suited for deep learning applications. It can directly read up to 384 GB of memory to accommodate fast access to imaging data for inferencing. Thus, it can better meet the requirements of AI-based CT image analysis compared to other AI processing technologies.
英特爾可擴展處理器系列非常適合深度學習應用程序。它可以直接讀取高達384GB的內存,以便快速訪問影像數據進行推理。因此,與其他人工智能處理技術相比,它能更好地滿足基于人工智能的CT圖像分析的要求。
Intel? Optimization for TensorFlow* leverages the Intel? Math Kernel Library for Deep Neural Networks (Intel? MKL-DNN) to help improve performance on image data processing. Plus, it has customized 5,000 new features to provide better support for medical image analysis issues.
英特爾TensorFlow*優化利用英特爾深度神經網絡的核心庫(英特爾MKL-DNN)幫助提高影像數據處理性能。此外,它還定制了5000個新功能,以更好地支持醫學圖像分析問題。

加速人工智能的圖像分析和診斷
Intel worked with JianPei Tech to optimize their image- reading robot on Intel Xeon Scalable processors for inferencing of X-ray, CT, MRI, and other medical imaging sources. To accelerate image analysis, JianPei Tech’s plat-form was migrated to Intel? Xeon? Gold 6140 processors and optimized with Intel Optimization for TensorFlow, which includes the Intel MKL-DNN library.
英特爾與健培科技合作,優化英特爾至強可擴展處理器上的影像閱片機器人,以推理X射線、CT、MRI和其他醫學成像數據。為了加快圖像分析,健培的平臺被移植到英特爾?至強?金 6140處理器,并使用英特爾? TensorFlow優化庫(包括英特爾? MKL-DNN庫)進行優化。
As shown in Figure 1, the collaborative work resulted in achieving an 8X performance improvement on DICOM (Digital Imaging and Communications in Medicine) images (identified as DCM in Figure 1).1 The speedups were a result of using Faster R-CNN* (Region Convolutional Neural Network) instead of UNet* and optimizing the Faster R-CNN algorithms for Intel Xeon Scalable processors.
