人心脏的准确几何定量是诊断多种心脏疾病的关键步骤,以及心脏患者的治疗。超声成像是心脏成像的主要方式,但是采集需要高操作员的技能,由于工件,其解释和分析很困难。在3D中重建心脏解剖结构可以使发现新的生物标志物,并使成像降低对操作员专业知识的依赖,但是大多数超声系统仅具有2D成像功能。我们提出了对PIX2VOX ++网络的简单变化,以大大降低存储器使用和计算复杂性,以及从2D标准心脏视图中对3D解剖结构进行重建的管道,从而有效地从有限的2D数据中启用了3D解剖学重建。我们使用合成生成的数据来评估管道,从而从只有两个标准的解剖学2D视图中获得准确的3D全心重建(峰值相交> 0.88)。我们还使用真实的回声图像显示了初步结果。

Data Centers are huge power consumers, both because of the energy required for computation and the cooling needed to keep servers below thermal redlining. The most common technique to minimize cooling costs is increasing data room temperature. However, to avoid reliability issues, and to enhance energy efficiency, there is a need to predict the temperature attained by servers under variable cooling setups. Due to the complex thermal dynamics of data rooms, accurate runtime data center temperature prediction has remained as an important challenge. By using Gramatical Evolution techniques, this paper presents a methodology for the generation of temperature models for data centers and the runtime prediction of CPU and inlet temperature under variable cooling setups. As opposed to time costly Computational Fluid Dynamics techniques, our models do not need specific knowledge about the problem, can be used in arbitrary data centers, re-trained if conditions change and have negligible overhead during runtime prediction. Our models have been trained and tested by using traces from real Data Center scenarios. Our results show how we can fully predict the temperature of the servers in a data rooms, with prediction errors below 2 C and 0.5 C in CPU and server inlet temperature respectively.
