What is 4-D imaging?

Professor Rusty Lansford explains that modern imaging techniques use four dimensions - the x, y, and z spatial coordinates, as well as one other critical variable - time.

4-D imaging is slang for four-dimensional imaging. By that, we that mean we are imaging in x and y [axes], just normal space. Z would be depth and then t, is typically what we call that 4th dimension, is time. We are trying to dynamically image a developing organism, so we all develop in three dimensions, we walk around in a three-dimensional world and we’re trying to dynamically image that all in time. So in a sense we’re not taking snap shots of a developing embryo we are literally taking movies – like this.
