Medical robotics is an interdisciplinary field that came into existence to improve medical
procedures utilizing robotics technology. Medical robotics range from minimally invasive …

Purpose Accurate and precise needle placement is of utmost importance in interventional
radiology. However, targeting can be challenging due to, eg, tissue motion and deformation …

Steerable instruments allow for precise access to deeply-seated targets while sparing
sensitive tissues and avoiding anatomical structures. In this study we present a novel …

In virtue of a curved insertion path inside tissues, needle steering techniques have revealed
the potential with the assistance of medical robots and images. The superiority of this …

Medical phantoms can be used to study needle-tissue interaction and to train medical
residents. The purpose of this research is to study the suitability of polyvinyl alcohol (PVA) as …

During ultrasound-guided percutaneous interventions, needle localization can be a
challenge. To increase needle visibility, enhancements of both the imaging methods and the …

Accurate needle placement in deep-seated liver tumours can be difficult. In this work, we
disclose two new manually controlled steerable needles for 17G radio-frequency ablation …

Purpose The purpose is to design and validate an anthropomorphic polyvinyl alcohol (PVA)
liver phantom with respiratory motion to simulate needle-based interventions. Such a system …

Objective: Needle insertion is a common component of most diagnostic and therapeutic
interventions. Needles with asymmetrically sharpened points such as the bevel point are …

High repeatability of needle insertion experiments is essential to the needle-phantom
interaction model validation. However, the influential factors governing the accuracy of the …
