Obtained following recent bound-relaxation results, the optima of the cost functions yield each kidney region in near real time. The Dice Metric (DM), the Jaccard Index (JI), and the correlation parameter have been adopted as validation parameters in order to evaluate the segmentation results. The obtained relative function of both kidneys has been then compared with that evaluated in clinical routine (planar projection) and then validated statistically by the Bland–Altman plots and the Interclass Correlation Coefficient (ICC). 结果。相较于专家手册肾脏分割,所获得的结果已被判定为具有高平均数骰子公制(MDM)值和高的Jaccard指数(JI)临床使用是可接受的。所评估的相对肾功能已经从那些通常在临床例程中使用的投影平面的方法来计算不同。 结论。所提出的系统可以有效地提取肾区。相对函数估计可以被视为更准确。事实上,背景噪声校正和衰减的现象,这可能会产生肾异位的错误措施,是可以避免的。我们的临床工作人员验证结果和临床使用程序等工具建议。SN - 2040年至2295年UR - https://doi.org/10.1155/2020/6092305 DO - 10.1155 /六百○九万二千三百○五分之二千○二十○JF - Hindawi出版KW - - ER杂志医疗工程PB的 -
