Ultrasound Scanner Latest Trends
Many research works are being conducted to improvise and bring more efficient models of ultrasound scanners. This section gives a clear cut vision of the latest trends and ongoing research aimed at ultrasound scanner improvisation. Some of the very important research works listed out: 1) Ultrasound Spatial Compound Scanner for Improved Visualization in Vascular Imaging 2) Methods for Determining Low Contrast Detectability of Ultrasound Imagers 3) Ultrasound and MRI Phantom Development 4) Disease Characterization in the Renal System and Breast 5) Non-Contact Ultrasound for Osteoporosis and Bone Imaging
Ultrasound Spatial Compound Scanner for Improved Visualization in Vascular Imaging A new off-line multi-angle ultrasound compound scanner has been built with the aim of improving visualization of vascular tissue. Images are recorded from 3 to 11 insonification angles over a range of 40 to 50 degrees and the individual images are combined (averaged) into a single image (spatial compounding).
Quantitative Ultrasound Imaging Standard ultrasound images though of good quality, are not quantitative because equipment technical settings on the scanner can be varied freely at the discretion of the sonographer, there is no absolute calibration of the echo data, and each patient differs somewhat in how rapidly the tissues absorb the ultrasound energy. Methods are being developed for quantifying ultrasound attenuation and ultrasound backscatter levels from data acquired by ultrasound scanners. 3-D Ultrasound Scanner Provides In-depth View of the Brain Biomedical engineers at Duke's Pratt School of Engineering have adapted a three-dimensional ultrasound scanner that might guide minimally invasive brain surgeries and provide better detection of a brain tumor’s location. Methods for Determining Low Contrast Detectability of Ultrasound Imagers In medical ultrasound, there is a lack of effective methods for medical physicists and sonographers to evaluate the performance of this equipment. The phantoms and algorithms also will be used for routine quality assurance tests of ultrasound scanners. Ultrasound and MRI phantom development Test objects and phantoms that provide realistic, tissue-like challenges to imagers while still being well characterized spatially and physically, are essential in ultrasound and MRI research. They also are invaluable for doing performance tests of imaging equipment in hospitals and imaging centers. Disease Characterization in the Renal System The primary aim of this project
is to evaluate current non-invasive ultrasound techniques, capable of
diagnosing all grades of blockages (stenosis) in the main artery supplying
blood to the kidney (renal artery). Secondly, to develop an
understanding of disease progression in the renal artery through
experimentation. This work is carried out in collaboration with Dr Carmel
Moran from the Medical Physics Unit at the
Disease Characterization in the Breast The purpose of this project is
to provide evidence for the case to redefine the role of diagnostic
ultrasound in breast screening and also in symptomatic breast imaging. This
work is carried out in collaboration with Dr Fidelma Flanagan, Niall Phelan
and Gillian Egan of breast check
Due to the rapid rate at which the performance and imaging capabilities of ultrasound scanners are being improved, designing performance test procedures and test phantoms which will challenge state-of-the art, top-of-the range ultrasound scanners represents a growing challenge.
Ultrasound Technology in Equine Cardiology and Musculo - Skeletal Imaging The 1990's heralded great improvements in the imaging quality of scanners and transducers. The creation of the Weipers Centre for Equine Welfare witnessed the purchasing of the latest ultrasound scanner in 1997.
Non-Contact Ultrasound for Osteoporosis and Bone Imaging This site displays a paper which concerns two results that although very preliminary could have an impact on the diagnosis and treatment of osteoporosis, the thinning and loss of elasticity of bone that eventually affects everyone in advanced age. This demonstrated that ultrasound attenuation (scattering and absorption) can reveal the mineral density of the bone-like material, which is made of a mixture of bone ash and Vaseline. |
