projection from CT scan geometry

Richard Cole
Dear Group

I have a rotational series (1o increment) of images collected in a geometry
similar to NMR or CAT scan.  The imaging mode is called optical projection
tomography.  Sharp et.al. Science. 296(5567):541-5, 2002 Apr 19. Basically,
images are taken as the object is rotated through the depth of focus. I am
trying to project this series to create a volume.  Any suggestions would be
greatly appreciated.

Cheers

RWC

Hi Richard,

what you need to do is a backprojection (inverse Radon transform) of your
projections, this can be done on ImageJ through the VolumeJ API. You can find
the usage of the VJProjection class here,
http://bij.isi.uu.nl/ImageJ/api/VolumeJ/VJProjection.html.
Others methods are available outside of ImageJ, you can ask me if you
want more
details.

Cheers,

Arnaud
