DOI: 10.1117/1.jmi.9.6.065002
Abstract: Abstract. Purpose Current ultrasound (US)-image-guided needle insertions often require an expertized technique for clinicians because the performance of tasks in a three-dimensional space using two-dimensional images requires operators to cognitively maintain the spatial relationships between… read more here.
