[Gate-users] Problems with output image from example_ARF

[Pietrzyk, Uwe]

Dear Leda,

could you send me the macro-files (*.mac) you are using
to have a direkt look at the output. Did you also produce
root-files and did you look at the data through ROOT to check
they look consistent?

Kind regards and best wishes,

Uwe

Dear Uwe,

I’ve just tried to read the projections as you suggested, but it doesn’t work. I don’t know which is the problem.

Kind regards and best wishes.

Dear Leda,

soon, there will be a new EduGATE example called SPECT_To_Reco and from
this example I copy the read me to read the projections with Fiji / ImageJ (See below).

I hope it works in your case too.

Kind regards and best wishes,,
Uwe

# File: Readme_reco_demo_Fiji.txt
# Fiji / ImageJ import of GATE-projections and reconstructed images:

-----

# Projections:

# use: File -> Import -> raw -> select "file".sin

# to be taken from .hdr-file
# size of projection: 128x128 pixel
# No. projections: 60
# -> file contains 60 images of 128x128 pixel (width x height)
# unsigned 16 bit integer
# littleendian

Dear Gate-users,

I tried to execute the template macro files  provided in the folder /examples/example_ARF. When I execute the macro “useARFTables” I obtain the output image (“benchARFMultiProjections.hdr”  and “benchARFMultiProjections.sin” ) but when I try to open it with ImageJ I obtain an image which is not correct. The simulated source is a point one but the output image is not representing a point source. I sent you a screen shots of one projection.

Do I make anything wrong?
Please help me.
Leda
