INCREASING PRECISION OF EDGE RECOGNITION IN STATIC RENAL

Yousif. Mohamed. Y. Abdallah

Abstract :

A region of interest (ROI) technique of renal scintography is a portion of an image that filter by using some algorithm. In dynamic tests of kidney, the segmentation of the kidneys performed using edge detection and basic morphology tools in MatLab image processing program. The gradient image calculated and a threshold applied to create a binary mask containing the segmented liver. First, I used Sobel edge technique. I then tuned the threshold value and used edge again to obtain a binary mask that contains the segmented kidney. Finally, in order to make the segmented kidney look natural, I smoothened the kidney by eroding the image twice with a diamondstructuring element. Less than 3% of cases (50 cases). The effectiveness of the segmented images with use of these kidney borders was arbitrated by a nuclear medicine physician as being comparable to other segmentation techniques created with manual editing. This technique showed potentials to precisely detect the liver with nuclear medicine images.
