hello  
I have a telemed system that its output is .vol and i need to convert these images.  
when i drag and drop my file and click Ok to loading nothing happens.  
if somebody had this problem i would be thankful if help me to solve it.

Unfortunately, this .vol file contains data compressed with an unknown algorithm. Can you save data as DICOM or some other format or get specification of the file format from the manufacturer?

I think only Telemed can help you to convert your existing 3D files.

If attaching an external tracker (such as a webcam that track 2D barcodes that you print and attach to the probe) is acceptable then you can use Plus toolkit ([www.plustoolkit.org](http://www.plustoolkit.org)) and SlicerIGT extension to show live images in Slicer and reconstruct 3D ultrasound volumes from freehand sweeps. See more information at [www.slicerigt.org](http://www.slicerigt.org).
