Popis:	The asymmetric film-screen system InSight HC represents a development to optimize chest imaging. The purpose of the study was to compare the exposure range and the image quality of this new system with a conventional film-screen system. The optical density of images in both techniques was measured and the image quality of 100 chest images from 50 intensive-care patients was evaluated. 4 observers graded the image quality of organic, non-organic and pathological structures. Statistical evaluation was performed by interobserver analysis. The asymmetric film-screen system shows a larger exposure range and a superior image quality in the mediastinal field. The image quality in the peripheral field must be judged critically and improved especially because of the poor recognizability of pneumothoraces.
