Thread Subject: Volume Of Interest

Hello All,

I am using matlab for my project, i am wondering if it is possible to draw a volume of interest on the 3D dataset.

For Example, i can use functions imrect, imellipse, etc... to draw a 2D region of interest in 2D image/slices. but is there a way i can draw a cuboid/cube i.e. a 3D volume of interest on a 3D volumetric dataset formed by the multiple 2D slices?

Kindly suggest
Thanks a lot.
