TLDR
First in-vivo results from test persons and patients with breast lesions are presented and it is shown in vitro that FASC also improves contrast perfusion imaging.Abstract:
For the detection of breast cancer, ultrasound is conventionally used in addition to mammography However, ultrasound is highly operator-dependent since speckle, depth dependency and other artifacts (eg shadowing) affect image quality Full Angle Spatial Compounding (FASC) may overcome those limitations by superimposing ultrasound data acquired in one cross-sectional plane from aspect angles all around an object Furthermore, we showed in vitro that FASC also improves contrast perfusion imaging To apply FASC to breast imaging, we developed an add-on system to a conventional ultrasound scanner, integrated in a custom-made examination couch Here, we present first in-vivo results from test persons and patients with breast lesionsread more

Sound-speed image reconstruction in sparse-aperture 3-D ultrasound transmission tomography
TL;DR: These issues are addressed in terms of sound-speed image reconstruction, using edge-preserving regularized algebraic reconstruction in combination with synthetic aperture focusing, and the critical points of the implementation are discussed, because they are crucial to enable a complete 3-D image reconstruction.

A novel experimental approach for three-dimensional geometry assessment of calcified human stenotic arteries in vitro
R.W. Boekhoven,Richard G.P. Lopata,Marc R.H.M. van Sambeek,Frans N. van de Vosse,Marcel C. M. Rutten +4 more
TL;DR: An in vitro experimental method is proposed for accurate 3-D assessment of (diseased) vessel geometry using ultrasound that does not suffer from acoustic shadowing effects present when imaging stenotic segments and allows future dynamic measurements to determine mechanical properties of atherosclerotic plaque in an in vitro setting.
Mechanical characterisation of healthy and diseased carotid arteries using ultrasound
TL;DR: An in vitro experimental method is proposed for accurate three-dimensional assessment of (diseased) vessel geometry using ultrasound that does not suffer from acoustic shadowing effects present when imaging stenotic segments and allows future dynamic measurements to determine mechanical properties of atherosclerotic plaque in an in vitro setting.

Snakes : Active Contour Models
TL;DR: This work uses snakes for interactive interpretation, in which user-imposed constraint forces guide the snake near features of interest, and uses scale-space continuation to enlarge the capture region surrounding a feature.

Speckle in ultrasound B-mode scans
TL;DR: In this paper, the reduction in speckle that can be obtained with a compound scan with maximum amplitude writing is computed and the condition for the independence of two amplitude values is derived.

An ultrasound research interface for a clinical system
TL;DR: The ultrasound research interface (URI) is an optional feature providing several basic capabilities not normally available on a clinical scanner and its use on three research examples: elastography, computed tomography, and spatial compounding is illustrated.
