To many people radiology is synonymous with films. For 20 years or so, however, it has been possible to capture digitally data traditionally displayed on film, and that was true from the beginning of computed tomography and magnetic resonance imaging

Digital Video Fluorography (DVF) has been developed over the past fifteen years. Although much emphasis has been placed upon digital subtraction angiography (DSA) the concept has been extended to gfluoroscopic examinations. Indeed, 1024 x 1024 DVF sy

Teleradiology has been discussed for many years yet its use to thte has been limited. An important factor is the need for adequate image quality so that a diagnosis can be made with confidence. We have developed several generations of digital fluoros

A feasibility study for the photographic recording of fluoroscopic images from a high resolution system is described. Resolution on the television monitor was 2 line pairs/mm, making clinically acceptable recordings possible. Significant reductions i

The combination of videofluorography and pulsed fluoroscopy using an analog videodisc system has previously been investigated with regard to image quality and potential for dose reduction. The authors found that the system could be improved still fur

The image quality of photofluorographic spot films (70, 100 or 105mm) has bee gradually improving as high resolution image intensification has evolved. With newly available 1023-line fluoroscopic monitors providing 2.8 line pairs/mm resolution, it is
