Do you have any idea of the format of the .dat file? Like how many rows, columns, or slices?

There is 128x128x243 integer, 8 bit

I understand that you want to open the image stored in the "vox_man.dat" file which is of the size 128*128*243. You can use MATLAB's "fopen", "fread" and "fclose" functions to read image data stored in .dat file as shown below.
% Open the file for reading
fileID = fopen('vox_man.dat', 'r');
% Specify the image dimensions and data type
imageWidth = 128;
imageHeight = 128;
numChannels = 243;
dataType = 'uint8';
% Read the file contents into a vector
imageVector = fread(fileID, imageWidth * imageHeight * numChannels, dataType);
% Close the file
fclose(fileID);
%imageVector now contains the data stored in vox_man.dat file in a vector
%format, you can now reshape your data as per your requirement for further
%analysis.
For visualizing the image you may have to perform some statistical operations on your image data to reduce the number of channels to form an RGB or a grayscale image.
You can refer to the following MathWorks documentation to understand more about "fopen", "fread" and "fclose" functions respectively.
I hope this helps.

Here are the missing lines they forgot to add to the end of their script:
%imageVector now contains the data stored in vox_man.dat file in a vector
%format, you can now reshape your data as per your requirement for further analysis.
image3D = reshape(imageVector, [imageHeight, imageWidth, numChannels ]);
% Display options:
% Display the 3-D volumetric image slice by slice.
for k = 1 : numChannels
imshow(image3D(:, :, k), []); % Show slice k.
caption = sprintf('Displaying slice %d', k);
title(caption);
drawnow;
end
% Bring up in 3-D volume viewer.
volumeViewer(image3D)
