Patent Images

1. An apparatus for the extraction of blood flow rate in an internal organ of a human body by analysis of a time sequence of scintigraphic images taken from the internal organ comprising:

  • means for digitizing scinitgraphic data, whose amplitude represents the time sequence of activity of a radioactive tracer in the internal organ;

    means for storing and retrieving a first plurality of orthonormal functions cz ;

    means for storing and retrieving a second plurality of orthonormal functions dz having the same number of elements as function cz ;

    means for calculating a set of values fz from the product of the elements of dz and the amplitude value of each pixel of each of said images; and

    means for calculating said blood flow rate from the sum of the products of each individual element of cz and fz.
