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
