Automated full-field volumetric ultrasound

An automatic full-field volumetric breast ultrasound scanner (AFFBUS) is a developing technology which was initiated to overcome the drawback of dense breast and to get a three dimensional view of the breast. 

Components

  • scan station
  • view station
Scan station

Automatic ultrasound imaging acquisition of the breasts is done by acquiring volumetric data. A rigid, pivoted stationary frame is manually pushed so that the the transducer with gel applied on it comes in contact with the breast and an optimal scan is acquired.

View station

The acqired data is analyzed and converted into thin tomographic slices. There is a facility to use a virtual probe by which multiple other scan planes can be acquired and a lesion if visualized can be better demonstrated with its adjacent structures. The viewing can be done in cine mode or by regular grey scale images. Post processing may be done and finally the interpretation is done based on the data acquired in the various planes.

Advantages

  • good demonstration of breast anatomy
  • reproducible images due to improved lesion localization 
  • provides information for CAD of breast lesion
  • no significant trained competence required
  • time efficient
  • better overview of breast anatoy
  • negative reading competence improved
  • highly accurate

Disadvantages

Due to high pick up and demonstration of lesions, rate of inadvertent aspirations and biopsy is high.
