Abstract

Simple chest radiography is the most frequently performed examination in radiologic practice. However, with transmitted dose through chest which has the problem of wide variations in absorption, conventional Film/Screen Combinations Method make it difficult to delineate lung field mediastinum & cardia portion and subdiaphragmatic structures. In order to overcome this problem, we have been tried several methods as follows. High Kilovoltage Technique, Rare Earth Screen/Wide Lattitude Film, Use of Compensating Filter and Digital Beam Attenuator and recently Insigh System has been developed. In this paper, we'd like to discuss Insight film through apperciation by measuring the difference of contrast. In order to evaluate insight film. We have done experiments using Insight System with Simple Phase, Picker 550. We could get an result which was able to overcome the limitted dynamic range of conventional Film/Screen System remarkably.
