title: [Studies on computer analysis of multi-frame renal images--multiple regional renograms and functional images (author's transl)].
abstract: A method of making the multiple regional renograms and simple functional images are described. Thirty-six EDTA (or DTPA) images has been transferred from a gamma camera to a small computer with the magnetic tape. Thirteen regional renograms from a kidney have been made by using the single pixel ROIs from these images, a continuous 13 pixels horizontal and/or vertical of the matrix are selected, in distinction from right and left kidney. Two functional images have been made by the multi-frame images as a peak arrival time and it's peak counts. Small change of the radioisotopic transportation in the kidney could be observed by the method, and change of the urodynamics could be extracted by two functional images. It will be actualize quantitative diagnosis to the renal function disorders.
