Fast detection of breast position for 3D USCT

The 3D USCT II system needs a method to localize and reposition a non-centrally positioned breast. A novel imaging technique (IIT) was introduced to retrieve intersection images of breasts. By detecting the breast deviation direction from these images, the breast position can be estimated. This method limits the amount of data and speeds up the data transmission by producing only 2D images and generalizing the breast as convex. It achieves an mean accuracy of 0.73° for the estimation of the breast deviation direction. IIT achieves a data reduction rate of 99.99%, which speeds up the data transfer to 0.1 s. Therefore, IIT achieves a fast and sufficiently accurate detection of the breast position for USCT II system.
