实时三维经食管超声心动图对二尖瓣脱垂瓣叶立体结构的定量研究
Chinese Journal of Ultrasound in Medicine（2011）
Abstract
目的 探讨二尖瓣脱垂时二尖瓣叶的几何形态特征.方法 采用Philips iE33超声心动图仪,经食管三维探头X7-2t.应用实时三维经食管超声心动图对32例二尖瓣脱垂患者和32例二尖瓣正常的患者定量二尖瓣叶参数.结果 二尖瓣脱垂组的二尖瓣前叶、后叶的面积和长度,对合线长度均较正常对照组增大(P＜0.05).两组间穹窿高度和容积,前叶、后叶与瓣环夹角、前叶与后叶夹角的差异无统计学意义(P＞0.05).结论 实时三维经食管超声心动图能对二尖瓣叶的立体结构进行定量分析,为外科医师提供了二尖瓣脱垂瓣叶的立体结构数据.

- 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
