Thanks again
I have been playing with similar things now since I got the message from
Oleg this morning.
By the way this bmp image I got by using dcmtk toolkit and dcm2pmn to
extract the image from a DICOM file
I used dcm2xml to extract the header info for the same DICOM file
I got a xml file from an instrument used to do measurements and is shown
inside the phantom displayed on the DICOM images
I am going to collect info from all three files to compare times and do some
calculations based on the values gathered.
I am very happy to have all these tools available and it is sure easy to do
this inteactively with J.
I have learned more about all of this in a matter of days - with massive
assistance from the forum also - than I am sure it would have taken doing it
with some other set of tools.
PS: the example you sent is great in addition to the rest
There was a similar problem here as I was seeing earlier with the xml test
scripts
load 'media\image3\view_m'
|file name error: script
| 0!:0 y[4!:55<'y'
You may have done some changes in profile or something but I need to add
addons and .ijs
load '~addons\media\image3\view_m.ijs'

Björn,
You shared with me the image privately and I can offer my
first reactions, but this might be a spoiler, so don't
read below if you don't want my knee jerk reaction to the image
you sent.
Best,
Cliff

load 'media\image3\view_m'

The image appears to be grayscale, mostly very neutral.

Yes, just 8 grayscales, very close together
view_image (n i. b){<:32*1+i.8

Show the distinct grayscales with lots of contrast. (Could also
use colors for even more contrast). Click to get pixel
location of features that interest you.
