Methods and systems for removing occlusions in 3D ultrasound images

Buckton D.J., Schröcker G., Varchola A., Bruckner S., Gröller E., Novotny J.
US9390546B2 (2013 USPTO), WO2015065565A1 (2014 WIPO), December 2014

Methods and system for visualizing 3D ultrasound data are provided. One method includes obtaining image slices from a volumetric image data set and generating a ray profile using one or more rays through at least one of the image slices, wherein the one or more rays extend along a depth of the volumetric image data set. The method further includes identifying one or more seed points along the one or more rays and defining a clipping surface using the one or more seed points, wherein the clipping surface defines a rendering region within the volumetric image data set. The method also includes rendering a 3D image of the rendering region within the volumetric image data set. Read more

Using Virtual Reality Effectively in Scientific Data Exploration - Perception, Usability and Design in Immersive Displays

Novotny J. (Advisor: Laidlaw D.H., Committee: Bowman D.A., Tompkin J.)
PhD. Thesis - Brown University, July 2020

In recent years, the rising popularity and availability of Virtual Reality (VR) systems has enabled the use of immersive display systems for scientific data exploration. This opened up a large design space for novel visualization techniques that needs to be thoroughly investigated in order to build practical software. This dissertation investigates aspects of creating effective VR visualizations from multiple angles: First, by analyzing how display fidelity affects user performance immersive data exploration situations. Here, results from a large scale study evaluating the factors of display resolution, field of view and display artifacts show their varying impact on user effectiveness depending on the exploration tasks presented.

Application of Smart Visibility on Medical 3D Ultrasound Datasets

Novotny J. (Advisors: Gröller M.E., Varchola A.)
Master Thesis - Vienna University of Technology, May 2013

Ultrasonography is one of the standard medical imaging techniques used in pregnancy examinations. It is widely available due to its low cost, portability and simple diagnostic procedure. In recent years, three-dimensional ultrasound (US) imaging has been gaining popularity in the area of prenatal care. It provides examiners with a coherent visualization of the fetus. However, within scanned 3D datasets, the fetus is often surrounded by occluding structures which reduce its visibility in the resulting visualizations. Current ultrasound machines provide several methods to remove these occluders from visualizations. These methods are often difficult to control in the real-time setting of an US examination session. As a result, the work flow of US examinations has to be interrupted in order to apply occlusion removal to selected scans. Read more
