Read a series of dicom slice images to a 3D volume image and meta data.

This function reads all good dicom files in a given directory and outputs a volume image. The slices are sorted by the SliceLocation tag in the image header. If no directory is specified, it opens a folder browser.

It also collects user specified (or default) header information for each slice and calculates some additional data for each slice such as the physical width and height of the image (e.g. PhysicalWidth = PixelWidth(1)*Rows). It also determines some meta data about the image such as the physical aspect ratio which is useful for volume rendering utilities.

Finally, it saves all the data to the dicom directory as a MAT file. In the future, the user will be able to switch the file saving on and off, and also specify alternate formats.

Version Published Release Notes

Added robustness in handling directories with subdirectories (Mac OSIRIX users end up with these), very large data sets (>2GB), and missing header info. Changed screen outputs to fprintf in case user wants to compile.

Fixed a few bugs. Better handling of empty directories or insufficient header info for some calculations. Slight improvements to documentation and organization.

Fixed a bug.
