see a 2d plane from a 3d image

The code to form a sphere of 100x100x10 pixels is the following

    % 
imageSizeX = 100;
imageSizeY = 100;
imageSizeZ = 100;
[X,Y,Z] = ndgrid(1:imageSizeX, 1:imageSizeY, 1:imageSizeZ);
% Next create the circle in the image.
centerX = 50;
centerY = 50;
centerZ = 50;
radius = 25;
circlePixels = (Z-centerZ).^2 + (Y-centerY).^2 + (X-centerX).^2 <= radius.^2;

I would like to visualize a horizontal plane 2d in some position z of the sphere in a square of 100x100 pixels, obviously this image would be a circle.

How would that be done, thank you very much.

Try slice().

[Marcelo hernandez]

matlab says that Input grid is not valid MESHGRID. i try

    % 
  xslice = 10;   
yslice = [];
zslice = [];
slice(X,Y,Z,circlePixels,xslice,yslice,zslice,'nearest')

Try this:

imageSizeX = 100;
imageSizeY = 100;
imageSizeZ = 100;
[X,Y,Z] = ndgrid(1:imageSizeX, 1:imageSizeY, 1:imageSizeZ);
% Next create the circle in the image.
centerX = 50;
centerY = 50;
centerZ = 50;
radius = 25;
circlePixels = (Z-centerZ).^2 + (Y-centerY).^2 + (X-centerX).^2 <= radius.^2;
circlePixels = double(circlePixels);
zslice = 50;
slice(circlePixels,[],[],zslice,'nearest')
