Movement of the patient's head during computed tomographic studies with the EMI scanner causes some degradation of the quality of the examination. With sufficient movement, major artifacts appear which may obscure intracranial pathology. A simple method of head fixation, utilizing a dental mold, greatly reduces the incidence of unsatisfactory scans.
在使用EMI扫描仪进行计算机断层扫描研究期间，患者头部的移动会导致检查质量有所下降。如果移动幅度足够大，就会出现严重伪影，可能会掩盖颅内病变。一种利用牙模的简单头部固定方法可大大降低扫描结果不理想的发生率。
