摘　　要：目的研究SPECT/CT骨断层扫描中,探寻采集速度与图像质量间的平衡点。方法自2014年4月以来,每2个月为1周期,逐步调节采集条件。有三位医生诊断融合后SPECT/CT图像质量为基础,结合图像分辨率综合评价采集条件调整后的图像。结果 7种采集条件所拍摄的图像均符合诊断要求。"方案3"方法推广于临床工作最佳。结论骨断层扫描中采集参数可以设置5 s/帧,合计64帧(5.625o),探头自动贴近,扫描方法为连续,所获得的SPECT图像的采集效率高。同时推荐使用"连续"代替"步进"方法采集骨断层显像。Objective To study and search for a balance between the image quality and acquisition speed in tomography of whole body bone scan.Methods Adjustments of acquisition conditions were carried out gradualy every two months since April 2014. The qualities of fused SPECT/CT images were diagnosed by three doctors. Then the picture would be evaluated comprehensively by analyzing image quality and image resolution after adjusting image acquisition conditions.Results Seven kinds of image acquisition conditions taken were in line with diagnostic requirements. The third method is extended to clinical work best.Conclusion To obtain a high colection effi ciency, parameters of bone tomography acquisition can be set a frame of 5 seconds, total 64 （5.625o）, automatic probe close and continuous scanning. Also recommends the use of ＆quot;continuous＆quot; instead of ＆quot;step and shoot＆quot; approach in bone SPECT acquisition. tomography, emission-computed, single-photon, bone tomography, program optimization.
