4D Echo VR use issues

I wanted to reach out about our recent challenges viewing 4D echo in VR utilizing Slicer. We are able to get the 3D data into Slicer, but we are only getting one time point of the cardiac cycle. We are taking 3D acquisitions scanned on a Philips-EpiQ echo machine. We are exporting the data from the machine as Dicom converting it in Philips Qlab software to cartesian dicom and then pulling into 3D Slicer for 3D visualization. We have also tried to load the dicom export directly from the machine into Slicer with the same results. Any help would be much appreciated!
