I would like to process MicroCT data with a file size of 16GB, but Mimics supports file sizes not bigger than 4 GB. Is there a possibility to reduce the resolution of DICOM images?
Maybe you can crop the area of interest of those image by using image processing packages such as Amira or even just Matlab. Or just use other packages rather than mimics
You can convert dicom to jpeg and reduce resolution in any viewer (FastStone, XnView). I tried this part yesterday. The hardest part is to convert jpeg to dicom - maybe you should try some hints from this page: http://dicomiseasy.blogspot.com/2011/10/converting-bitmap-jpeg-and-pdf-to-dicom.html.
You can crop the area of interest in the beginnig before you convert the data in mimics, but this is only possible if there are parts that you don't need. If you need the whole window it is useless.
It's also possible to reduce your data. You can take only half of your datafiles of your DICOM folder, copy them in a new folder and convert this folder in MIMICS.
