• A-projective module
• left self-injective von Neumann regular ring
• injective dimension
• annihilator

In this paper, we introduce the concept of A-projective modules and define a kind of "global" dimension ICTID(R), which measures how far away a ring is from being a left self-injective von Neumann regular ring.
