Real-time beam visualization and therapy planning for focused ultrasound therapies using a diagnostic imaging array
… was then overlaid onto a co-aligned B-mode image captured using the same imaging array to provide anatomical context. To correct for the scattering profile of the medium, the echogenicity of the B-mode image was used to normalize the intensity field reconstruction, allowing for robust …

Null subtraction imaging technique for biomedical ultrasound imaging
… of lateral sidelobes results in an improved image with less distortion and fewer artifacts. In general, apodization is used to lower sidelobes in exchange for increasing the width of the mainlobe and thus decreasing lateral resolution. Null subtraction imaging (NSI) is a nonlinear image …

Improving ultrasound display by retrieving high-frequency sonographic information
… of the system, which is an important factor in image quality. The axial resolution of ultrasonic B-mode images has been studied by Wagner et al. (1983) and shown to be on the order of the pulse bandwidth. However, a broad pulse bandwidth, which is obtained at high transmission frequency, has …

Spatial Coherence-Based Adaptive Acoustic Output Selection for Diagnostic Ultrasound
… the acoustic exposure levels used do not benefit image quality, they represent an unnecessary risk to patient safety. Ultrasound users have control over many settings, including ones that directly and indirectly change the acoustic output, and the user is largely responsible for deciding how to …

Real time motion tracking in image guided focused ultrasound intervention
… ultrasound (USgFUS), diagnostic ultrasound B-mode image was used to track a moving target. The possibility of using strain sonoelastography to assess FUS lesion formation was explored.<br/>Multi-layered tissue mimicking phantoms were designed and fabricated to mimic the graphical features of …
