小角度断層撮影技法の検討

抄録

The valuation of tomographic technic at small angles utilizing rectilinear apparatus was carried out on account of numerical preponderance of this mode of the movement. A phantom was designed to attain moderate photographic contrast and its tomographic images were surveyed densitometrically. Several clinical cases also have been pursued. The application of rectilinear apparatus into this field is still regarded as practically worthwhile provided that appropriate objects and direction are selected from the viewpoint of neighbouring structures and supposes contrasting status.
