title: New technologies in nerve location.
abstract: Regional anaesthesia is undergoing a renaissance, perhaps assisted by the introduction of (and enthusiasm for) ultrasound-guided regional anaesthesia into clinical practice. This article summarises the technology and principles of ultrasound imaging in anaesthesia and describes the development of three-dimensional ultrasound imaging, considering whether this new technology has an application in regional anaesthesia.
