Possibility to digitized imaging of gastric mass examination by means of high resolution x-ray television system

In this study we discussed about possibility of digitized imaging of X-ray gastric mass examination by means of high resolution X-TV system. The results may be summarized as follows: 1. Dose per a image in this system is one-tenth indirect radiography by image intensifier. 2. Maximum resolving power on final image is 1.5 LP/mm. 3. Dynamic range of new system is seven-tenth of conventional system's. 4. Operating to take the image data is easy and fast. These results indicate the possibility of application on gastric mass examination. Though this system have several problems to be solved, it is possible to make use of our system that be able to applicate various image processing and to make imaging data base for expert system.
