This is my first question about Fiji.
I made a scan with a Inveon pre-clinical microCT with 120 projections. In the post-processing, I only want to analyze the first 45 because of the contrast injection during the first 60 seconds of the scan (aprox the first 45 projections). To my knowledge,tThe software of the microCT does not support reconstruction of only a subset of the projections.
I found the source file, which is a .cat file. I can open it in imageJ and make a subset of the first 45 slices. However, i cannot save it in the original file-format .cat.
The software of the microCT only accepts .cat files, so i have to find a way to cut out the first 45 slices for reconstruction. (or find another program to do the reconstruction)
Can anybody help me saving the file as .cat (or convert for example?
Thank you all in advance!
