Calculate volume

Quantifying tissue morphology, or shape is one primary objective of biomedical imaging. The size, shape, and uniformity of a tissue can reveal essential health insights.

For this exercise, measure the volume of the left ventricle in one 3D image (vol).

First, count the number of voxels in the left ventricle (label value of 1). Then, multiply it by the size of each voxel in mm\(^3\). (Check vol.meta for the sampling rate.)
