  • Title: [The determination of the surface and organ doses in the AMBER system. Advanced Multiple Beam Equalization Radiography].
    Author: Herzog R, von Boetticher H, Luska G.
    Journal: Rofo; 1993 May; 158(5):483-6. PubMed ID: 8490159.
    Abstract:
    Surface and organ doses were determined by means of thermoluminescence dosimetry with the Alderson-Rando phantom and the patient, for the AMBER thoracic imaging system, sensitivity class 400, and the conventional grid screen stand, sensitivity class 200. The dose on entering the body, which varied according to object-dependent modulation of x-ray intensity, was 140 microGy for the mediastinum and 96 microGy for the lung in p.a. AMBER takes, and hence was comparable with the entrance dose of 132 microGy with the conventional grid screen stand. In lateral takes the entrance doses were lower with the AMBER system (302 microGy) than with conventional takes (593 microGy). Exposure of the gonads at the AMBER system for p.a. thoracic takes was lower than at the screen grid stand in females (4-6 microGy). More unfavourable values were measured for the gonad exposure in males (2-0.8 micrograms).
