How to calculate the total voxelvalue?

Dear all,

I have the code below. the problem is, I want to calculate the total voxel value in table.

Just now what I doing is the total voxel value I have to copy first in workspace table, then paste in excel, then I summation it. very take time.

anyone can help me?

I try replace "VoxelValue" to "TotalVoxelValue", but it doest not work

All the data set as attached.

I-131sphere10nisbah1.dcm = I-131sphere10nisbah1.mat

Segmentation.seg.nrrd = Segmentation.seg.mat

clc
clear all
close all
[spect map]=dicomread('I-131sphere10nisbah1.dcm');
spect= squeeze(spect);
info = dicominfo('I-131sphere10nisbah1.dcm');
g = nrrdread('Segmentation.seg.nrrd');
figure; imshow3D(g)
figure, imshow3D(spect)
data = regionprops3(g,spect,'Volume','VoxelValues', 'Centroid')

sum(g, 'all')

maybe?
