Three-dimensional reconstruction of images is a fundamental procedure in medical imaging because it allows to build virtual models of anatomical units of the human body, useful in several areas, such as in surgical navigation. This paper presents a non freehand Ultrasound acquisition system for human femur reconstruction where the probe displacement and(More)
This paper presents the integration between the Image Guided Surgery Toolkit (IGSTK) and the Point Cloud Library (PCL) to deliver a software tool (SWT) to robotic orthopedic surgery. The application that demonstrates the usefulness of the tool was developed for the registration of 2D ultrasound (US) images of the femur to 3D point clouds obtained from CT or(More)
Intelligent Robots can take advantage of a distributed, web-based information system deployed in the cloud to perform high level tasks. This paper proposes a robotic control framework suited to be used by low-cost robots, performing teloperated and/or autonomous tasks. The first part is dedicated to the development of an Android based robot control(More)
