Ideal configuration for intravenous digital subtraction angiography machine.

An assessment of the current state of development of digital imaging systems is provided as well as recommendations for future areas of investigation, including the incorporation of large-field image intensifiers, higher raster rate TV systems, and high speed digital disks into digital subtraction angiography (DSA) machines. Recent advances in hardware and software developments are discussed as they pertain to the X-ray generator and tube, X-ray image sensors (image intensifiers and TV cameras), and the image processor of the DSA system.
