The article focuses on the need for digital subtraction radiology in medical imaging in Great Britain. The X-radiation is considered as a diagnostic tool despite the contributions from far safer energies. Thus, a photographic technique has been introduced in 1930's to eliminate the unwanted information from the X-ray film due to a visceral movement found in the patient from the generated image. However, electronic noise and inaccurate image processing has been found in the early 1970's.
