General theory of operation

The main purpose of the ABUS is to scan breast tissue and
collect information about its condition. To do that, the ABUS
performs ultrasonic imaging. That is done as follows:
The Transducer in the Scan Head has an array of 128
piezoelectric crystals. Each of the piezoelectric channel's signal
is sent by an individual wire in the transducer cable back to the
Ultrasound Box for processing.
The PC the GPU card convert the digital scan data into image
form. The images are shown on the operator monitor and are
stored in the PC memory in the SSD (solid state drive). From
there the images can be sent to a compatible image viewer such
as the GE Workstation for ABUS 2.0.
For imaging, additional image enhancement, noise reduction,
and speckle reduction algorithms are performed. The data is
then converted to display scan data for the final image output.
The following figure outlines general flow of data from Invenia
ABUS 2.0 to external systems for image data handling.
