These limitations of real-time 2D ultrasound imaging were addressed with the use of optical
tracking technology and frameless neuronavigation. Fixating a frame with spherical …

OBJECTIVE: The combination of classic neuronavigation and intraoperative ultrasound is a
recent innovation in image guidance technology. However, this technique requires two …

In recent years there has been a considerable improvement in the quality of ultrasound (US)
imaging. The integration of 3D US with neuronavigation technology has created an efficient …

Since the first recorded use of the “ultrasonoscope” for localizing subcortical intracerebral
neoplasms in postmortem specimens in 1950 (4), technological advances in ultrasound …

Intraoperative sonography has been used in neurosurgery since the 1950s. The first
ultrasound (US) modality introduced was A-mode, which did not produce anatomical …

OBJECTIVE: In 1995, a project was initiated in Trondheim, Norway, to investigate various
possibilities for more frequent use of ultrasound in brain surgery. Since that time, the quality …

Abstract Study Aims: The purpose of this study was the integration of three-dimensional
ultrasound data into a neuronavigation system, in order to allow a guided intraoperative …

OBJECTIVE: Three-dimensional (3-D) ultrasound is an intraoperative imaging modality used
in neuronavigation as an alternative to magnetic resonance imaging (MRI). This article …

Objectives: Many commercial neuronavigation systems offer tracked 2D ultrasound.
However, visual comparison of preoperative MRI with intraoperative ultrasound is often …

Background Intraoperative ultrasound (iUS) allows the generation of real-time data sets
during surgical interventions. The recent innovation of 3D ultrasound probes permits the …
