How to find XZ plane along with XY plane in 3D Dicom Image?

if i have XY = V(:,:,160);, whic plane XZ ( which plane i have consider as XY plane)? can giving a idea's ?

Hello voxey,

In a 3D DICOM image, the data is typically represented as a 3D matrix or volume.

As you mentioned, XY = V(:,:,160); extracts the 160th slice along the Z-axis. This is a 2D slice parallel to the XY plane.

To extract an XZ plane, you need to fix the Y-coordinate and vary X and Z. For example, if you want the XZ plane at a specific Y position (say, y = 100), you can extract it as:

XZ = V(100,:,:);

This will give you a 1xMxP matrix, which you might need to squeeze to get a typical 2D matrix:

XZ = squeeze(V(100,:,:));

Similarly, to extract a YZ plane, fix the X-coordinate and vary Y and Z. For example, for a specific X position (say, x = 50), you can extract it as:

YZ = V(:,50,:);
YZ = squeeze(V(:,50,:));
