1. The user select an US video file in the mp4 format for loading and specifies the approximate imaging plane and the distance between first and last frame of the video sweep (Fig 2).
2. Next, the median still image of the video is presented, and the user is prompted to place a caliper over a distance of 4 cm using the scale present on the still image (Fig 3).
3. Finally, the user is asked to draw a region of interest in the still image specifiying which part of the cine loop to be used for the volumetric dataset (Fig 4).

List of cases

• Axial sweep of the upper abdomen (Distance between first and last video frame: 17 cm; Duration 21 s)
  
  Viewer | download (MP4)

  Axial sweep of the upper abdomen. ... This case can illustrate how double oblique MPR is possible with Sonoviewer; users can for an example perform reconstructions such that the abdominal aorta can be viewed in a (plane perpendicular to the aortic flow direction). Read more

• Sagittal sweep liver (Distance between first and last video frame: 15 cm; Duration 17 s)
  
  Viewer | download (MP4)

  By default 3 orthogonal plans are displayed in Sonoviewer. ... In this case, these approximate the standard axial, sagittal, and coronal planes. Having these planes available for review one can determine in which segments focal liver lesions are located according to the Couinaud classification. As an example, a transverse plane through the horizontal portion of the right portal vein separates segments 7/8 superiorly from 5/6 inferiorly. Segments 5/8 anteriorly are separated from 6/7 by extrapolating a line along the right hepatic vein from the inferior vena cava to the lateral liver margin. An axial cross-section of segment 5 obtained in this way is shown (here). To further illustrate, by using the functions rotation and synchronization, it is possible to display a (longitudinal view) of the extrahepatic bile ducts. In addition, thick-slab minimum intensity projection (minIP) images allow volume visualization of hypoechogenic structures such as blood vessels - in this case the (liver veins). Read more

• Axial-oblique sweep right kidney (Distance between first and last video frame: 12 cm; Duration 9 s)

  Demonstrates reconstructions of the thyroid ... gland. The coronal plane is not otherwise obtainable or viewable with conventional two-dimensional acquisitions. Read more

• Axial sweep of left-sided hydronephrosis. (Distance between first and last video frame: 12 cm; Duration 4 s)
  
  Viewer | download (MP4)

  Axial sweep of left-sided hydronephrosis. Reconstructed coronal view of the dilated ... renal pelvis becomes possible. A CT dataset obtained the same day as the US is available to demonstrate how the Sonoviewer MPR functionality facilitates comparison between imaging modalities. Read more

• Axial sweep of left-sided renal graft. (Distance between first and last video frame: 13 cm; Duration 8 s)
  
  Viewer | download (MP4)

  This case demonstrates thickening of the renal ... pelvis/ureter of this left-sided renal graft. In addition, a perinephric haematoma is seen. The MPR functionality allows for better delineation of the extent of the haematoma in relation to the renal graft. MRI scan (T1 weighted 5 mm axial slices) available for comparison. Read more

• Axial sweep left thigh (Distance between first and last video frame: 8 cm; Duration 6 s)
  
  Viewer | download (MP4)

  Case showing the blood vessels ... of the left thigh. Notice how the transducer compression of especially the superior femoral vein hampers the quality of the acquired dataset as it makes it difficult to achieve reconstructions where the blood vessels can easily be differentiated. Read more

• Axial sweep left thigh (Distance between first and last video frame: 7.5 cm; Duration 11 s)
  
  Viewer | download (MP4)

  Ultrasound of the scrotum ... showing left-sided epididymitis primarily involving the caudal region. Read more

• Axial sweep of the urinary bladder (Distance between first and last video frame: 10 cm; Duration 5 s)
  
  Viewer | download (MP4)

  Ultrasound of the urinary bladder ... with a suprapubic catheter. The catheter ballon is seen in the bladder lumen, and the drainage tube is seen exiting the lower anterior portion of the bladder to the left. Read more
