Adaptive ultrasound imaging of the lumbar spine for guidance of epidural anesthesia
Computerized Medical Imaging and Graphics , 10/27/09
Tran D et al. – A non–rigid registration method, called warping, shifts pixels of the beam–steered images to best match the reference image. Linear prediction is used to find the warping vectors and decrease computational cost. An adaptive median–based combination technique for compounding is also investigated. The algorithms are tested on a spine phantom and human subjects. The results show a significant improvement in quality when using warping with adaptive median–based compounding.
