Quality control plugins for nuclear medicine

[O'Brien.Joseph]

Dear Nuclear Medicine ImageJ-ers!

I'm putting together a list of all the plugins for analysing nuclear
medicine type data (e.g. gamma camera QC data)

At present, all I have is the interfile and dicom import/export program!

Any others out there which people use?
        E.g. FWHM from a line profie
                NEMA and IPEM unformity analysis
                COR analysis
                Linearity

Ah, yes... I can confirm that.
If I scale up the M51 image by 9 (2880x4590) if get funny values just by

pressing Set and Ok. But this is happening occasional in my setup (about
once
every 20).

Hello Joe,

Few years ago we have developed a toolkit based on ImageJ in order to  
perform basic QC for SPECT (COR => AAPM, Uniformity => AAPM+IPEM) and  
PET (SF + PSF and MTF => special methodology from a french group). We  
don't have any time to actualize this plugin but it is possible to  
send you the toolkit + the proceeding of the SPIE congress where it  
was announced.

This toolkit will be certainly embedded in a more general tool called  
"Optimage" (see http://santec.tudor.lu/projects/optimage) dedicated  
to analysis of QC medical images (as far as I know the nuclear  
medicine section is still in development).

Let me know if you are interested in.

Dear Joe,

as Thomas already mentioned, we have some modules for QC of nuclear
medicine equipment. We curently have two modules testing the following:

Module Level A:  Intrinsic non-uniformity (EN 60789)

Module Level B: center of rotation, resolution and linearity (and some
more)

The Module Level A ist well tested and stable, where Module Level B is not
tested that much. You might start using the Module Level A directly from
our free download. As Level B is not that stable, this is not available
there. But I can send it to you and you can have a look.... .

Best Regards,
Andreas
