Maxillofacial tomography apparatus (MT tomography) is a panoramic tomographic unit, radiographing in recumbent position. Its image can show most of the anatomic structures of maxillofacial bones. Through comparative examination between the conventional roentgenograms (general radiographs, pantomographs and laminagrams) and MT tomography of 48 patients, it is found that MT tomography has certain advantages for the diagnosis of the range, extent and quality of fracture, tumour and tumour like disease in maxillofacial bones and that MT tomography can serve as an effective auxillary method of diagnosis for the conventional roentgenograms used for maxillofacial bones.
颌面断层摄影装置（MT断层摄影）是一种全景断层摄影设备，在卧位进行摄影。其影像能够显示颌面骨的大部分解剖结构。通过对48例患者的传统X线片（普通X线片、全景片和分层片）与MT断层摄影进行对比检查，发现MT断层摄影在诊断颌面骨骨折、肿瘤及肿瘤样病变的范围、程度和性质方面具有一定优势，并且MT断层摄影可作为颌面骨传统X线片的一种有效的辅助诊断方法。
