Given that image registration is a fundamental and ubiquitous task in both clinical and
research domains of the medical field, errors in registration can have serious consequences. …

During the last two decades, intra-operative ultrasound (iUS) imaging has been employed
for various surgical procedures of the spine, including spinal fusion and needle injections. …

Objective. Accurate localization, classification, and visualization of intracranial electrodes
are fundamental for analyzing intracranial electrographic recordings. While manual contact …

Mechanical site preparation by mounding is often used by the forest industry to provide
optimal growth conditions for tree seedlings. Prior to planting, an essential step consists in …

Purpose Accurate and effective registration of the vertebrae is crucial for spine surgical
navigation procedures. Patient movement, surgical instrumentation or inadvertent contact with …

Background The operative environment poses many challenges to studying the relationship
between surgical acts and patient outcomes in intracranial oncological neurosurgery. We …

Interpreting ultrasound (US) images of the spine is challenging due to the high variability of
the contrast during freehand US acquisitions. In this paper, an automatic method to extract …

BACKGROUND Navigation systems for spinal fusion surgery rely on intraoperative computed
tomography (CT) or fluoroscopy imaging. Both expose patient, surgeons and operating …

Objective: During an interactive image segmentation task, the outcome is strongly influenced
by human factors. In particular, a reduction in computation time does not guarantee an …

The speed of graph-based segmentation approaches, such as random walker (RW) and
graph cut (GC), depends strongly on image size. For high-resolution images, the time required …
