Analyzing Images HELP

[Katherine Huang]

Hi,
I am very new to this program and would appreciate any advice in  
analyzing qCT images.
I am using the tool that allows me to circumscribe a portion of the  
image, but would like to know if there is a command/plugin that will  
allow ImageJ to give me the dimension (in pixels) of the maximum  
width and height of the outlined portion.
When I obtain measurements from Analyze>Measure a small window pops  
up with values for Mean, Maximum, Minimum and Area.  I am not exactly  
sure what the first three measurements refer to, so any explanation  
would be helpful as well.
Thank you so much.

Katherine, the measurements are the average pixel value of the pixels in
the ROI, the Max and Min are the largest value and smallest value of the
pixels in the ROI.  --- Mike

If you go into Analyze->Set Measurements, you can determine the...
measurements which will be provided.  For example, the Bounding
Rectangle option will give you the "maximum width and height of the
outlined portion" that - I think - you are looking for.
