THE AMBER-THORAC-IMAGING IN THE DIAGNOSTIC ROUTINE

After installation of an Amber lung x-ray imaging system the range of application of this technique was registered for two month. Additional ly the image quality for structures of the lung parenchyma and mediast inum were proved and dose measurements were performed. 50.6 % (772) pa tients from a total of 1525 could be x-rayed by the Amber imging syste m. Related to all people able to stand 73.6 % from 1049 patients were examined with the Amber system. Most of the imaging figures of merid s pecified by the German national physician board were accomplished, bes ides the fact that 1/3 of the p. a. radiographs were cut off at the si de because of the small size of the film. The excellent image of pleur o-mediastinal structures was proofed quantitatively by counting the pl euro-mediastinal lines and comparing the results with standard radiogr aphs. Measuring the exposure at entrance point we obtained nearly the same values for the Amber system using a screen-film combination with a speed of 400 and conventional radiographs (40-120 mu Gy; 21 pat.).
