“…1,4,5 The first commercial 2D array system was manufactured by Volumetrics Medical Imaging (Durham, North Carolina, USA) at the end of the 1990s based on the technology developed by the group at Duke University led by Smith. Later, Philips Medical Systems (Amsterdam, Netherlands) produced a 2D array system with part of the beam forming within the transducer.…”

This article describes four technologies relevant to vascular ultrasound which are available commercially in 2015, and traces their origin back through the research literature. The technologies are 3D ultrasound and its use in plaque volume estimation (first described in 1994), colour vector Doppler for flow visualisation (1994), wall motion for estimation of arterial stiffness (1968), and shear wave elastography imaging of the arterial wall (2010). Overall these technologies have contributed to the understanding of vascular disease but have had little impact on clinical practice. The basic toolkit for vascular ultrasound has for the last 25 years been real-time B-mode, colour flow and spectral Doppler. What has changed over this time is improvement in image quality. Looking ahead it is noted that 2D array transducers and high frame rate imaging continue to spread through the commercial vascular ultrasound sector and both have the potential to impact on clinical practice.

“…The papers which are included-referred to below-fall naturally into several categories, the first of which can be thought of as being concerned with advances in mainstream technologies. These are those on medical ultrasound systems [7], ultrasonic colour Doppler imaging [8], three-dimensional ultrasonic scanning [9], vascular ultrasound for atherosclerosis imaging [10] and quantitative contrast-enhanced ultrasonic imaging [11]. The second category consists of papers on technologies that are just now beginning to impact upon clinical practice: real-time quasi-static ultrasound elastography [12], acoustic radiation force-based elasticity imaging [13] and ultrasonic image analysis and image-guided interventions [14].…”

Nowadays in the UK, more than one quarter of all clinical imaging procedures use ultrasound and the number of ultrasonic scans that are performed each year exceeds all of those done by X-ray computed tomography, magnetic resonance imaging and radionuclide scanning combined [1]. Doubtless, the situation is similar in the rest of the world, but with ultrasound being even more used in lessdeveloped countries, because of its relatively low cost. Diagnostic ultrasound has come into its ascendency over the last 60 years, mutating from a laboratory curiosity being developed and promoted by very few innovative engineers and visionary clinicians (for instance, in the USA [2], in Japan (see [3]), in Sweden [4] and in the UK [5]) into an indispensible tool in modern routine clinical practice.Each of the wide range of different imaging modalities has its own individual characteristics. Usually in practice, the choice of the optimal modality is fairly obvious, because it depends on the clinical problem being investigated. Thus, for example, an X-ray is appropriate if a fracture is suspected, because X-rays are good at imaging bones. Likewise, for the management of cancer, positron emission tomography-a type of radionuclide scanning-can be invaluable because of its ability to visualize malignant tissue. The relative advantage of any particular modality lies essentially in the mechanism of the contrast in the images which it produces. In this respect, ultrasonic imaging is rather versatile. Primarily, the image contrast depends on differences in densities and speeds of sound, because these properties determine the scattering and reflectivity of tissue. In addition, flow, motion, strain and elasticity can be estimated ultrasonically and used to produce parametric images, for example, by colour maps superimposed on images of scattering and reflectivity. Moreover, ultrasonic imaging is fast and apparently safe, as well as being well liked by patients. Thus, the technology is particularly valuable in clinical practice in obstetrics and gynaecology, internal medicine, genitourinary studies, cardiology, vascular studies, dermatology and breast disease, but it is not of much use in the investigation of gas-containing or bony structures.Ultrasonic imaging is a mature medical technology, the evolution of which has been the result of many years of biomedical engineering and clinical research. Moreover, the level of contemporary research activity is great and it covers a vast range of emerging opportunities. Very many ultrasound papers appear in medical journals devoted to the various clinical specialties and these generally report on the expansion of the diagnostic horizons, which results from novel applications and observations with existingalbeit often new-technologies. In organizing this Theme Issue of Interface Focus, however, we sought to compile papers that would be representative of advances in the technologies themselves, sometimes even before their clinical potentials have been explored. Of course, our intention certainly was ...

“…Based on Huygens' principle [4]- [6], ultrasonic phased array offers a new method of scanning and inspection. Ultrasonic phased array takes the advantages over the traditional ultrasonic inspection that it is needless to replace probes regularly, and has wide scanning range and manipulates simply [7]- [10].…”

Abstract-The material of the gas turbine blade is nickel base super alloy. When the blades are inspected the artificial evaluation can only be adopted to normal inspection due to the lack of industry benchmarks, which contributes to single indicator and large error. To solve this troublesome problem and help inspect the blades, this paper proposes a method of data analysis and processing. At first, the defects were recognized from the detected image, and then quantitation, qualification and location analysis were made from the recognized defects. Through comparing with the artificial evaluation, this method is a good one which can provide more parameters, has high accuracy and much reliability.Index Terms-Gas turbine, image processing, defect analysis, nickel base super alloy.
