    This study introduces a FORTRAN IV program for deconvolution analysis, calculating kidney retention functions from time-activity data. The software determines key parameters like mean transit time and plots essential curves for renal function assessment.

    Area of Science:

    • Nephrology
    • Medical Imaging
    • Computational Biology

    Background:

    • Accurate assessment of kidney function is crucial for diagnosing and managing renal diseases.
    • Traditional methods for analyzing renal function may lack precision or require complex manual calculations.
    • Deconvolution analysis offers a powerful approach to quantify renal parameters from dynamic imaging data.

    Purpose of the Study:

    • To present a FORTRAN IV program designed for deconvolution analysis of renal time-activity curve data.
    • To automate the calculation of kidney retention functions and associated kinetic parameters.
    • To provide visualization tools for renal function assessment, including plotting corrected time-activity curves and retention functions.

    Main Methods:

    • Development of a FORTRAN IV program utilizing a matrix algorithm for deconvolution.
