摘　　要：目的探讨三维超声容积自动测量技术在移植肾容积参数采集中的方法学问题。方法 20例肾功能稳定期移植肾患者,分为a取值30°、15°、9°、6°旋转步长组、同一操作者9°旋转步长组及不同操作者9°旋转步长组,进行三维血管容积参数的采集与分析。结果 a取值为30°、15°、9°、6°组,同一操作者a取值为9°前、后两次测量组以及不同操作者a取值9°分别测量组,所得到的三维血管容积参数比较差异均无统计学意义(P>0.05)。结论选取a取值9°为旋转步长,进行移植肾三维血管容积数据的采集最为适宜;三维超声容积自动测量技术在不同操作者内及相同操作者间的测量值变异小,重复性好。Objective To explore the methodology of transplanted kidney volume parameters collection by threedimensional ultrasonic volume automatic measurement. Methods Twenty renal allografi patients with stable renal function underwent virtual organ computer aided analysis （VOCAL） - imaging program with four different rotation steps （ a = 30°, 15°, 9° ,6°）. The parameters of four groups were analyzed. The three-dimensional vascular volume parameters of rotation steps group, the same operator 9°rotation steps group and different operator 9°rotation steps group were collected and analyzed. Results There was no significant difference of the parameters among four different rotation steps, the same operator 9°rotation steps and different operator 9°rotation steps groups （ P 〉 0.05 ）. Conclusion It is appropriate to employ the 9° rotation step for using VOCAL in transplanted kidney. VOCAL is reliable and valid in interobserver and intraobserver measurement.
