Hi all,
i try use the Gradient Weight segmentation funtion (as script).
I binarize it. Only got the volume (T1) like below. Means 178 multiply by the volume of one voxel(0.1ml) = 17.8 ml.
Can someone help me how to get the total counts, mean count, max count inside the volume??
Let say T1 is the first volume in my image in gray scale as picture attached.
T1 =
1×2 table
Area Centroid
____ __________________________
178 75.893 58.36 44.539
[spect map]=dicomread('I-131sphere10nisbah1');
info = dicominfo('I-131sphere10nisbah1');
%gp=info.SliceThickness;
spect=(squeeze(spect));%smooth3
aa=size(spect);aa=aa(3);
% NI KALAU VOLUME 1 10 NISBAH V1
seedR1 = 58; seedC1 = 76; seedP1 = 45;
W1 = graydiffweight(spect, seedC1, seedR1, seedP1 , 'GrayDifferenceCutoff', 1415);
thresh = 0.004196;
[BW1, D1] = imsegfmm(W1, seedC1, seedR1, seedP1, thresh);
figure, imshow3D(BW1)
T1 = regionprops('table', BW1,'Area','Centroid')
This is my gray image
this is after i segmentated it
