Not enough memory!!!

At the encouragement of Dr. Hatcher, I've recently started taking my scans at .2 & .3 mm. However, I'm finding that when I open the reconstructed data, I get a "not enough memory" message and have to close the program and reopen it to be able to open the data. Is this common or do I have something hogging memory in my computer?

Yes, this is a problem as Don and Amnon stated. I hope that Xoran will fix this soon.

I am glad you are varying the feild of veiw and the voxel size depending on the patient's conditions and the Dr.'s needs.

This phenomenon is caused by "memory fragmentation", which makes it impossible to find a large enough "contigous" chunk of memory required to open a particular study. We have been pressuring Xoran heavily to find ways to alleviate this problem, but unfortunately some of the underlying causes are entangled with Windows resource management and Microsoft development platform, in other words, a tangled mess. I am cautiously optimistic that the next iCAT software update would minimize this occurence.

On systems with 4GB of RAM, my opinion is that certain software resources and tools never look above the 2GB boudary anyway, thus obviating any benefit from this huge amount of memory.

Needless to say, higher resolution scans (hence larger data sizes) exacerbate this problem.
