Real-time image-based rigid registration of three-dimensional ultrasound
Registration of three-dimensional ultrasound (3DUS) volumes is necessary in several applications, such as when stitching volumes to expand the field of view or when stabilizing a temporal sequence of volumes to cancel out motion of the probe or anatomy. Current systems that register 3DUS volumes either use external tracking systems (electromagnetic or optical), which add expense and impose limi...
متن کاملReal Time Image-Based Tracking of 4D Ultrasound Data
We propose a methodology to perform real time image-based tracking on streaming 4D ultrasound data, using image registration to deduce the positioning of each ultrasound frame in a global coordinate system. Our method provides an alternative approach to traditional external tracking devices used for tracking probe movements. We compare the performance of our method against magnetic tracking on ...
متن کاملReal-Time Ultrasound Imaging Simulation
This paper introduces UltraSim, a computer-based interactive simulator device designed to train physicians and technicians in medical diagnosis using ultrasound systems. Students using the system are able to learn how to identify and diagnose a wide range of medical cases by operating a simulated ultrasound machine on a mannequin, without any need for actual patients. This application relates t...
متن کاملApplication of adaptive image processing technique to real-time spatial compound ultrasound imaging improves image quality.
RATIONALE AND OBJECTIVES To assess the impact of adaptive filter postprocessing on quality of ultrasound images. METHODS Ultrasound images acquired with real-time spatial compound imaging (SonoCT imaging) were subsequently processed with an adaptive real time algorithm (XRES imaging). Conventional and XRES-processed images from abdominal, pediatric or small parts ultrasound explorations were ...
متن کاملReal-time transverse process detection in ultrasound
PURPOSE: Ultrasound offers a safe radiation-free approach to visualize the spine and measure or assess scoliosis. However, ultrasound assessment also poses major challenges. We propose a real-time algorithm and software implementation to automatically delineate the posterior surface patches of transverse processes in tracked ultrasound; a necessary step toward the ultimate goal of spinal curvat...
