How to plot surf for 3D images.

Dear all, I have 3D image as attached. How to plot it using surf fucntion? so that i can get the graph as below.

>> h = dicomread('h.dcm');
>> h = squeeze(h);
>> surf(h);
Error using matlab.graphics.chart.primitive.Surface
Value must be a scalar, vector or array of numeric type.

Error in surf (line 145)
hh = matlab.graphics.chart.primitive.Surface(allargs{:});

Answer 1

dicom will be a 3D matrix..you cannot use surf straight away.

h = dicomread('h.dcm');
[m,n,p] = size(h) ;
figure
hold on
for i = 1:p
    surf(h(:,:,i))
end

Have a look on slice

unzip('h.zip')
h = dicomread('./h/h.dcm');
whos h

  Name        Size                    Bytes  Class     Attributes

  h         130x130x1x74            2501200  uint16              

h = squeeze(h);
whos h

  Name        Size                  Bytes  Class     Attributes

  h         130x130x74            2501200  uint16              

figure();
surf(h(:,:,1))
title('First Slice')
colormap(jet());
colorbar();

figure();
surf(h(:,:,end))
title('Last Slice')
colormap(jet());
colorbar();

figure();
surf(sum(h,3));
title('Sum of All Slices')
colormap(jet());
colorbar();
