Dynamic Scan DICOM File how to seperate into frames by number of counts

Hi,

I have a DICOM file of a 'Dynamic Scan' which has 15000 frames. I would like to sum each frame until it reaches 20M counts and then loop to continue and sum until the entire set of frames has been split into 20M count files. How would I go about doing this?

Thanks.

I assume the scan is too large to load at once? If not, how is the scan represented in data? If it is a 3D matrix, you can use a double call to sum followed by cumsum to find the frame numbers where you want to make the split.
