报告摘要：

近些年来，基于深度学习的方法在放射影像分析中取得了很好的效果，而预训练是取得这些成果的基础。预训练方法期望获得迁移性更好的图像表征，以往的预训练通过在源域上进行大规模全监督或者自监督学习来达到目的。但是，全监督的预训练需要图像的标签，制作标签是一个费时费力的工程，而自监督学习目前与全监督还有一定的差距。为了解决这个重要问题，提出一种交叉监督的方法，该方法使用放射影像自带的报告来作为监督信息进行预训练，也可以同时处理患者的多张放射影像，从而获得更加全面的信息。

报告摘要：

With the development of deep learning in medical imaging, how to learn the anatomical structure knowledge to guide specific tasks (i.e., segmentation and detection) is an essential yet challenging problem. This talk will present some of our recent works about shape-aware tooth segmentation in digital dentistry, including 3D CBCT and intra-oral scanning data. We will also discuss how to effectively define and learn anatomical knowledge in medical imaging.

报告摘要：

Our group has developed dozens of deep learning models for various medical image analysis tasks. Some of them won prestigious best paper awards while some others are highly cited and widely used in subsequent research works. However, we still face a lot of challenges that prohibit these models to be widely and effectively used in clinical practice. In this talk, we shall re-discuss these models from an epistemological perspective, aiming at understanding these interconnected challenges more clearly and paving the way in the intervening haze for developing clinically applicable models.
