摘要

本综述侧重于正电子发射断层扫描(PET)成像算法,并追溯 PET 图像重建方法的演变。首先,我们概述了从滤波反投影到最新迭代 PET 图像重建算法的传统 PET 图像重建方法,然后回顾了三大类 PET 数据深度学习方法直至最新创新。第一类涉及 PET 图像去噪的后处理方法。第二类包括直接图像重建方法,以端到端方式学习从正弦曲线到重建图像的映射。第三类包括将传统迭代图像重建与神经网络增强相结合的迭代重建方法。我们讨论了 PET 成像和深度学习技术的未来前景。

Deep learning-based PET image denoising and reconstruction: a review.

This review focuses on positron emission tomography (PET) imaging algorithms and traces the evolution of PET image reconstruction methods. First, we provide an overview of conventional PET image reconstruction methods from filtered backprojection through to recent iterative PET image reconstruction algorithms, and then review deep learning methods for PET data up to the latest innovations within three main categories. The first category involves post-processing methods for PET image denoising. The second category comprises direct image reconstruction methods that learn mappings from sinograms to the reconstructed images in an end-to-end manner. The third category comprises iterative reconstruction methods that combine conventional iterative image reconstruction with neural-network enhancement. We discuss future perspectives on PET imaging and deep learning technology.
