    Abstract
    目的：应用正电子发射计算机断层成像术/电子计算机X射线断层扫描技术( Positron Emission computed Tomography/elec-tronic Computer X-ray Tomography ，PET/CT )探讨呼吸门控采集时采用不同时相对PET图像与CT图像融合的影响。方法将行PET/CT显像发现肺部有结节的14例患者分为两组，应用呼吸门控技术对肺部结节进行不同时相的PET/CT显像，观察PET图像与CT图像的融合合格率。结果时相多的一组，可以得到更好的融合图像，优于时相少的一组。结论 PET/CT采集中，应用呼吸门控技术适当增加采集时相有意义，可以使PET图像与CT图像更好地进行融合，具有较高的临床应用价值，可在临床应用中逐步普及。

    • Pretraining has recently greatly promoted the development of natural language processing (NLP)
    • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
    • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
    • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
    • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
