It can be used when discussing a topic or concept that is related or similar to a previously mentioned idea or direction.
Example: "The research findings along this same axis suggest a correlation between the two variables."
Alternatives: "in this same direction" or "on this same line".
Use of orthogonal scan patterns in this work was motivated by the observation that multiple volumes scanned along the same axis from the same retinal area do not always guarantee that motion artifacts will be randomly distributed from one volume to the next.
