Reconstructing Raw data
Sorry, I didn't intend to be "missing in action" for the last week or so. However, a trip to Florida and a steep increase in tech support calls directed my way due to Samantha's maternity leave caused a major backlog in my e-mail.
To answer Matt's question, 0.4 mm and 0.3 mm scans can be interchangeably reconstructed, and so can the 0.2 & 0.25 scans. However, the boundary between these 2 groups should not be crossed. Although the system might permit it, there would be no gain in "real" resolution, in fact there likely would be a loss.
Yris was reconstructing across this boundary for the specific purpose of minimizing halo/circumference artifacts.

Arun:
If I reconstruct a .4mm scan to .3mm, do I get any benefit in exchange for the larger file and longer reconstruct time?
Reconstructing at 0.3mm does provide greater resolution and hence greater detail. Whether it provides true diagnostic benefit depends on the object being viewed/interpreted.
