Hi,

I´m not sure if I understand your request, because I also do not work in
CT. Do you basically say that you want to extend your image to areas where
there is no input data????

You should know that this is basically impossible, YET, for certain kinds
of further processing, it might be "possible", for example in cases where
you need to satify some boundary condition
of "fill up" to a certain size (as a power of 2 or a product of small
primes, for FFT or similar) without introducing too much "discontinuities".

You will better need to explain your special problem in more detail for a
useful answer IMHO, in the moment I know of no plugin that does this.

Sincerely

Joachim

Hi Juan,

Can you explain the question in simple words?
by matrix probably you mean 'image' and by FOV - the physical calibration of the image?
Note, that the jargon in your field is different from ours here.

best regards,

Dimiter
