The purpose of this study was to establish a method to obtain high valued diagnostic x-ray images by projecting the temporomandibular joint clearly using multipurpose rotational panoramic radiography.From a study concerning the position of an image layer and the direction of x-rays to the temporomandibular joints in rotational panoramic radiography, to obtain maximum information using TMJ rotational panoramic radiography, at least two projections (lateral and oblique) were necessary. The characteristics of these two projections were shown. (SUGAWARA)1) Oblique panoramic TMJ projection a) direction of projection From the standpoint of image formation theory by rotational panoramic radiography, it is difficult to obtain a frontal view of the condylar head at a closed mouth position. A lateral panoramic radiography in which the mandibular condylar heads are projected from the mesio-inferior anterior direction at a slightly open mouth position was excellent. (UEMURA, TAKEUCHI) b) image lay … More er To obtain a clearer image of the condyle, we changed the image layer thickness. As a result, at 9mm thickness of the image layer the most excellent turabecular pattern of condylar head can be seen. (KAWAGUCHI)2) Lateral panoramic TMJ projection at a closed mouth position (projection to long axis as parallel as possible) a) standard mode of lateral projection of TMJ At closed position contour of temporal bone could be recognized in only 60% of the cases. Position and direction of this projection seemed to be wrong. (KUDOH 1st) b) improvement of the image by changing the image layer thickness and position Changing the thickness and position of the image layer, the contour of the condyle and temporal bone were examined. Only at an image layer thickness of 6mm, and positioned 5mm laterally, the postglenoid spine was difficult to detect. (KUDOH 2nd). Concerning the position a condyle to image layer), a method for positioning the condylar head using the relationship between width of condylar heads and ear rods was studied. Less

本研究的目的是建立一种利用多功能旋转全景摄影技术清晰地投射颞下颌关节以获得高价值诊断X线图像的方法，通过对旋转全景摄影中图像层位置和X线对颞下颌关节方向的研究，利用TMJ旋转全景摄影技术获得最大信息，至少需要两个投影（侧向和斜向）。指出了这两种投影的特点。（SUGAWARA）1）倾斜全景TMJ投影a）投影方向从旋转全景放射摄影的图像形成理论的观点来看，难以获得在闭合口位置处的髁头的正面视图。侧位全景X线摄影，其中下颌骨髁状突头是从近中下向前的方向，在一个稍微张开的嘴的位置是极好的。（植村、竹内）B）图像层 ...更多信息 为了获得更清晰的髁状突图像，我们改变了图像层厚度。结果表明，在9mm厚的图像层上，髁突头的分子结构形态最佳。（川口）2）闭口位TMJ侧位全景投照（投照方向尽量平行于长轴）a）TMJ侧位标准投照模式闭口位时，仅60%的患者能辨认出颞骨轮廓。这个投影的位置和方向似乎不对。（KUDOH 1st）B）通过改变图像层的厚度和位置来改善图像改变图像层的厚度和位置，检查髁突和颞骨的轮廓。只有在图像层厚度为6 mm，并且横向定位为5 mm时，关节盂后棘才难以检测到。（KUDOH 2nd）。针对髁突相对于图像层的位置，研究了一种利用髁突头宽度与耳杆宽度的关系来定位髁突头的方法。少
