摘　　要：目的:分析Brain Time Stack图像融合技术在CT中的应用。方法:选取2021年3月—2022年9月衡水市第四人民医院收治的50例CT检查患者作为研究对象。所有患者进行CT检查并进行Brain Time Stack后处理。比较四组不同部位CT值、标准差(SD)、信噪比(SNR)。比较四组图像主观质量评分。分析不同部位CT值、SD、SNR与图像主观质量评分的相关性。结果:B组的延髓、额叶灰质、额叶白质、小脑内侧、小脑外侧、颞肌肌肉CT值明显低于A组;C组的延髓、脑室、额叶白质、小脑内侧、小脑外侧、颞肌肌肉CT值高于A组;D组延髓、额叶灰质、颞肌肌肉CT值明显低于A组,脑室、额叶白质、小脑外侧CT值明显高于A组;C组延髓、额叶灰质、额叶白质、小脑内侧、小脑外侧、颞肌肌肉CT值明显高于B组;D组延髓、脑室、额叶白质、小脑内侧、小脑外侧、颞肌肌肉CT值明显高于B组;D组延髓、额叶灰质、额叶白质、小脑内侧、小脑外侧、颞肌肌肉CT值明显低于C组;D组脑室CT值明显高于C组,差异有统计学意义(P<0.05)。B组、C组、D组延髓、脑室、额叶灰质、额叶白质、小脑内侧、小脑外侧、颞肌肌肉SD值明显低于A组;C组延髓、脑室、额叶白质、小脑内侧、小脑外侧、颞肌肌肉SD值均明显高于B组;C组额叶灰质SD明显低于B组;D组延髓、脑室、额叶灰质、额叶白质、小脑内侧、小脑外侧、肌肉SD均明显低于B组、C组,差异有统计学意义(P<0.05)。B组、C组、D组延髓、脑室、额叶灰质、额叶白质、小脑内侧、小脑外侧、颞肌肌肉SNR均明显高于A组;C组、D组延髓、额叶灰质、额叶白质、小脑内侧、小脑外侧、颞肌肌肉SNR值明显高于B组;C组、D组脑室SNR明显低于B组;D组延髓、脑室、额叶灰质、额叶白质、小脑内侧、小脑外侧、颞肌肌肉SNR明显高于C组,差异有统计学意义(P<0.05)。D组图像主观质量评分最高,差异有统计学�Objective:To analyze the application of Brain Time Stack image fusion technique in CT.Method:Fifty CT examination patients admitted to the NO.4 People's Hospital of Hengshui from March 2021 to September 2022 were selected as the study objects.All patients underwent CT examination and Brain Time Stack postprocessing.CT values,standard deviation(SD)and signalto-noise ratio(SNR)were compared in different parts of the four groups.The subjective quality scores of the four groups were compared.The correlation between CT value,SD,SNR and subjective image quality score was analyzed in different parts.Result:The CT values of medulla oblongata,gray matter of frontal lobe,white matter of frontal lobe,medial cerebellum,lateral cerebellum and temporal muscle in group B were significantly lower than those in group A.The CT values of medulla bulbar,ventricle,white matter of frontal lobe,medial cerebellum,lateral cerebellum and temporal muscle in group C were higher than those in group A.The CT values of medulla oblongata,gray matter of frontal lobe and temporal muscle in group D were significantly lower than those in group A,and the CT values of ventricle,white matter of frontal lobe and lateral cerebellum were significantly higher than those in group A.CT values of medulla oblongata,gray matter of frontal lobe,white matter of frontal lobe,medial cerebellum,lateral cerebellum and temporal muscle in group C were significantly higher than those in group B.The CT values of medulla oblongata,ventricle,white matter of frontal lobe,medial cerebellum,lateral cerebellum and temporal muscle in group D were significantly higher than those in group B.The CT values of medulla oblongata,gray matter of frontal lobe,white matter of frontal lobe,medial cerebellum,lateral cerebellum and temporal muscle in group D were significantly lower than those in group C.The ventricular CT value of group D was significantly higher than that of group C,and the differences were statistically significant(P<0.05).The SD value of medulla oblongata,ventricle,gra
