X-ray film of the month.

X-ray examination of the chest revealed a large circumscribed area of absent aeration in the central portion of the left lung which extended from the axillary portion of the chest to the hilum, merging with the mediastinal structures. In the lateral projection, this circumscribed area was superimposed over the heart. An aneurysm could not be excluded; the area of diminished aeration was thought...

The ABCs of chest X-ray film interpretation.

Gas under the diaphragm in x-ray film may mislead.

Gas under the diaphragm in xray film may mislead Pneumoperitonium is suspected when radiographs show the presence of gas under the diaphragm. Recognised causes of pneumoperitoneum include perforation of a viscus, recent abdominal surgery, peritoneal dialysis and Fallopian tube insufflation. Interposition of bowel, usually hepatic flexure of the colon, between the upper border of liver and the r...

Characterization of Liquid Crystal Alignment on Rubbed Polyimide Film by Grazing-Incidence X-Ray Diffraction

We developed a new method for characterizing molecular distribution in very thin liquid crystal layer (5–40 nm) evaporated onto rubbed polyimide film used by grazing-incidence X-ray diffraction (GIXD). The diffraction peaks corresponding to intermolecular correlation perpendicular to longitudinal axis of liquid crystal molecule and the clear anisotropic distribution of liquid crystal molecules ...
