Abstract

A timed series of video images (dynamic study) may be taken for a human organ under examination, after f.v. injection of contrast material. The images are digitized and stored as matrices of 512 x 512 pixels, Numerical data for each pixel within the sequence reflects then the temporal changes of the dye concentration in the tissue represented by that pixel according to a well-known X-ray attenuation logarithmic relation. A structured algorithm is developed to perform mathematical analysis and manipulation for those "functional images" on a pixel-by-pixel basis with the aim of deriving out some useful time-density variables and curves. The algorithm is app lied to 38 nor mal individuals to study their renal function and the results proved to be of a remarkable diagnostic value.
