I will echo Liz's comments. I occasionally scan slides with an older Scanscope 
XT.  It is worth the effort to clean and QC slides for artifacts as Liz points 
out as well as placing the section in the middle of the slide. Actual scanning 
is quite easy, each initial 'snapshot' is reviewed, AOI is resized to 
boundaries of the tissue and focus points are checked and verified to be 
overlaying tissue (not white space).
I find that adding more focus points across the section greatly increased the 
quality of the image and rarely have I found any areas out of focus. Once the 
snapshot reviews are completed simply hit the 'One Touch' icon and batch 
scanning begins.

I really like the ImageScope viewing program which lets one view the section 
and multiple magnifications, capture images, etc.. I have another system for 
IHC quantification, but other users are using the Aperio software to do that if 
that is part of your plan

They are not that difficult to operate but you do need person with some 
histology training scanning and QC'ing the slides and images.  The need to 
understand initially if the section is good enough to scan, we QC our slides 
prior to placing them on the scanner, ones that have sectioning artifacts may 
not scan that well.  Section placement on the slide is important, you can't 
have anything to close to the edge of a slide it will not scan well.   The 
person responsible for scanning makes sure that the slide is clean and does not 
have any excess mounting media prior to placing on the scanner, excess mounting 
media and dirt may cause the scan to be out of focus,  and then once the slides 
are scanned the scans need to be QC'd to make sure that they are good enough 
for the pathologist or whatever you are utilizing them for.  Quality and 
consistency in histology preparation is key for good scanning results.  These 
scanners scan in primarily one focal plane, meaning the pathologist loses the 
ability to fine focus as they would on a microscope.  They are able to fine 
focus through poorer quality sections or uneven sections, scanned images do not 
have a fine focus unless you scan them at multiple focal planes or z-stack.  I 
have seen some cytology images that have been scanned in a way that you have a 
fine focus slider but its not common for routine histology preps.

We take some time upfront to adjust area of interest and check focal points 
prior to scanning of the slides.  We find this works better than just going 
with the load and go method.  We review the snapshots prior to scanning.  I'm 
not sure what scanner you are getting or what version of the image capture 
software you will be using we have an Aperio ScanScope XT it has a 120 slide 
capacity.  On occasion a particular slide may not scan well, that’s why we like 
to review the snapshots.  For instance we were working on some amniotic 
membrane constructs these are a single cell layer thick so they are very thin 
and sometimes the computer does not pick the sample up as tissue because it so 
thin and can be lightly stained, so we need to place all of the focal points on 
the slides.  You may not have samples like this but you might.  

Good Luck  - feel free to contact me if you need any help once you get the 
scanner in house.

My department may purchase an Aperio slide scanner in the near future.  My 
question is - how tech savvy does one need to be to operate the device?  I have 
staffing concerns and the amount of training time involved.  Thanks in advance.
