How to open ultrasound files of General Electric devices?

The files has the extention .vol, and the format is called "Kretzfile 1.0". It is a 4D ultrasonic study for fetal heart analysis. Doctors called the analysis STIC (Spatio-Temporal Image Correlation). The images were adquired using an ultrasound system "Voluson 730" of General Electric. I need the images for my research project related to segmentation and optical flow estimation. Likewise, images can be stored in cartesian, spherical or cylindrical coodinate system.

Some free software packages that know how to deal with the .vol file are listed here. http://www.researchgate.net/topic/medical_imaging/

I hypothesize that one of the free DICOM might be able to output the result as a DICOM file.

The file format for the .vol files might be what is described here
