Ultrasound (US) has been proposed as a guidance tool for spinal intervention. However, bone structures are often visualized poorly in the standard US images which is based on the delay and sum beamforming method (DAS). In this study, we investigate combination of an eigenspace based beamformer (ESMV) with the phase symmetry (PS) post-processing technique to extract the lamina surface from ultrasound images. Thereby, in simulation, and in-vivo studies we show that an ESMV beamformer with a rank… CONTINUE READING
