Hi mohd akmal masud,
I understand you want to view the dicom images axially. You can use the 'imshow3dfull' function instead of 'imshow3d' function to attain the required functionality as it allows axial(A),saggital(S) and coronal(C) views.
You may find a documentation on the function here:
Please find the following example that shows how to use the function:
[X,map] = dicomread("US-PAL-8-10x-echo.dcm");
X=squeeze(X);
figure, imshow3Dfull(X)
For more information on the 'dicomread' function, please refer the following link: https://www.mathworks.com/help/images/ref/dicomread.html
Hope this helps.
