Appending Voxel Intensity with the Voxel Co-ordinates and Plotting ?

I have this two Data.

img_64_chest.mat = Voxel Intensity.

voxel_coords.mat = Voxel Co.ordinate [1st Col : X , 2nd Col: Y, 3rd Col: Z]

I want to append the data first and want to plot the image of the voxel intensity. It will be 4 dimensional Matrix : X coords, Y coords, Z coords, Voxel Intensity. I did this in Mathematica but not able to doing it in the MATLAB.

Any kinds of help will be appreciated. Thank you in advance for your kind assistance.

yes，sir，if show 3d，just use

load img_64_chest.mat
volshow(img)

then you can get 3d show

but what voxel_coords use to？add points on it？

Thank you for your response !

Yes I want to add the the points here in the image as well!

Hi,

You can use the location and intensity information to create and display a point cloud.

load img_64_chest.mat img
load voxel_coords.mat voxel_cords
ptCloud = pointCloud(voxel_cords,Intensity=reshape(img,[],1));
pcshow(ptCloud);
