摘要：

The aim of this work was to evaluate and possibly improve the CEC image criteria for radiographic chest images. Chest images of healthy Volunteers were acquired using different technique factors. The image criteria were used as a tool to discriminate between the different images. The technique factors were chosen so that the image quality would differ slightly. Four different technique parameters, each with two possible settings used in clinical practice today, were used: tube voltage, 102 and 141 kV; screen-film speed, 160 and 320; maximum optical density in the parenchyma, 1.3 and 1.8; method for scatter reduction, air gap and moving grid. The results showed that the image criteria were able to distinguish different technique groups. Optical density 1.8 was better than 1.3 independent of the other parameters. No difference was seen for screen-film speed. No correlation was seen between the ranking of the systems and patient dose.
