DISHA: Determination of Ideal Short-axis of the Heart Automatically

Pose determination of 3D objects is a topic of active research, particularly in the area of computer vision. The determination of the pose or orientation of a 3D object in a 3D dataset can be viewed as a two-fold problem : 1) The determination of the orientation of the object; and 2) the visualization of the object along with the determined orientation of the object. An attempt has been made to compute and visualize the orientation of left ventricle (LV) of the heart from SPECT data. A semi-automatic technique to first filter the acquired SPECT data and then compute the 3D orientation of the LV is under development. Volume visualization techniques have been employed to better visualize and comprehend the structure and orientation of the LV.
