Together with its clinical partners and advisory boards, Imperium is under development on a full line of medical imaging products for clinical use with DAV™. Our suite of Acoustocam™ imaging cameras* is focused on both imaging applications that current B-scan systems perform as well as expanded clinical uses that current ultrasound cannot satisfy. Images no longer exhibit unwanted speckle typically seen by conventional ultrasound images. Traditionally, B-scan ultrasound systems produce images which are perpendicular to the skin surface. Imperium's C-scan systems generate images which are parallel to the surface of the skin and records 2D plane images at different depths. Dr. Matthew Freedman of Georgetown University Medical Center writes: 

“The images shown provide additional information beyond that seen by conventional ultrasound, combining the images visible on conventional ultrasound and X-ray mammography.”

C-scan versus B-scan

Compared to conventional B-mode ultrasound, C-mode has the following advantages:

  • Much easier for non-specialists to interpret
  • Inherently lower cost
  • C-scan is free from speckle, an unwanted artifact seen on B-scan
  • C-scan is free from geometric distortion seen on B-scan
  • C-scan has far greater spatial resolution
  • It takes multiple round trips to generate one B-scan image. Sending more and more pulses improves image quality, but it sacrifices refresh rate. C-scan requires only one round trip to generate a full field image. There is no technical need to image at less than 30 fps.
  • C-scan images appear more naturally illuminated than B-scan images
  • C-scan therefore does not include the shadows that normally streak across B-scans
  • Structures in the C-scan appear to reflect ultrasound the way they would reflect light

    A figure showing the difference between B-scan and C-scan is shown below:
