Abstract: | Image compounding reduces the artifacts inherent in ultrasound imaging, but accurate matching of images for compounding depends
on their accurate placement in the compound image plane. A method is presented to reduce displacement errors during compounding
of ultrasound B-scans of a normal human shank. A genetic algorithm was used to place matching B-scans in the compound image.
The method was tested on a phantom and was shown to reduce, but not eliminate, mismatches due to the displacement of B-scans
from their original position in the compound image plane. The results can be extended to applications in lower-limb prosthetics,
where ultrasound imaging can be used to visualise the internal geometry of amputees' residual limbs. |
