High Resolution Tv Fluoroscopy and Image Storing

The investigation of the image-quality determining sections of the X-ray TV chain is an important matter for the optimization of the whole system. The modulation-transfer functions (MTF) of each component as the most important factor for the evaluation of the separate sections of the X-ray chain were measured. Special attention was given to gain exact measurements of MTF and other behavior of image pick-up tubes. In the second part of this paper image-quality determining factors and development tendencies of appropriate video stores for high resolution are discussed.
