SLOT Scan技术在青少年脊柱侧弯摄片中的应用

SLOT Scan imaging in teenagers with scoliosis

目的:探讨有技巧地应用一种新的窄缝曝光采集(SLOT Scan)技术对青少年脊柱侧弯摄片质量的提高作用。方法:使用日本岛津公司Sonialvision Safire Ⅱ设备,采用SLOT Scan技术对60例身高1.50米以上的青少年患者进行摄片。通过1次连续的曝光采集所有数据,再利用无缝全景拼接软件对图像缝合。结果:颈、胸、腰骶椎通过无缝拼接能同时在1张X线片上清晰地显示,达到了颈胸腰骶椎一次成像片的满意效果。结论:SLOT Scan技术作为一种全新的成像技术,能有效地去除拼接伪影,使全脊柱能同时在1张X线片上完整无缝地呈现,更有利于脊柱外科医生对侧弯的整体观察与计算测量,有利于手术方式的选择和疗效的判断。

Objective To explore the improvement effect of SLOT Scan technology （narrow seam exposure capture technology ） and the radiography techniques on the quality of the scoliosis X- ray films in teenagers. Methods The Sonialvision Satire Ⅱ equipment of Shimadzu corporation and SLOT Scan were applied to take the radiography for 60 patients taller than 1.50 metres. All the data were collected through a continual exposure, and the images were sewn up through a seamless connection software. Results Cervical, thoracic, and lumbar and sacral segments could clearly present at the same time on one X-ray film by seamless splicing, and the quality of one time radiograph was as good as one film. Conclusion As a new radiology technique, SLOT Scan can wipe off splitting arti- fact effectively and make the whole spine seamless present on one X-ray film. It helps the spinal surgeons to observe, calculate and measure accurately. It is useful to choose the operation mode and judge the curative effect.
