Synthetic aperture ultrasound (SAU) imaging is an advanced form of imaging technology used to form high-resolution images in biomedical ultrasound systems. Ultrasound imaging has become an important and popular medical imaging method, as it is safer and more economical than computer tomography (CT) and magnetic resonance imaging (MRI).
Photoacoustic imaging or optoacoustic imaging is a biomedical imaging modality based on the photoacoustic effect.Non-ionizing laser pulses are delivered into biological tissues and part of the energy will be absorbed and converted into heat, leading to transient thermoelastic expansion and thus wideband (i.e. MHz) ultrasonic emission.
Portable ultrasound is a modality of medical ultrasonography that utilizes small and light devices, compared to the console-style ultrasound machines that preceded them. In most cases these mobile ultrasound systems could be carried by hand and in some cases even operated for a time on battery power alone.
GE Healthcare Technologies, Inc. [1], organized in Delaware and headquartered in Chicago, Illinois, focuses on health technology.The company, which stylizes its own name as GE HealthCare, operates four divisions: Medical imaging, which includes molecular imaging, computed tomography, magnetic resonance, women’s health screening and X-ray systems; Ultrasound; Patient Care Solutions, which is ...
The latest Olympus camera is the Olympus OM-D E-M10 Mark IV as of 20 August 2020. Olympus M.Zuiko Digital ED 60mm f/2.8 Macro Lens. At one time, Olympus cameras used only the proprietary xD-Picture Card for storage media. This storage solution is less popular than more common formats, and recent cameras can use SD and CompactFlash cards.
The notion of acoustic microscopy dates back to 1936 when S. Ya. Sokolov [1] proposed a device for producing magnified views of structure with 3-GHz sound waves. However, due to technological limitations at the time, no such instrument could be constructed, and it was not until 1959 that Dunn and Fry [2] performed the first acoustic microscopy experiments, though not at very high frequencies.
X-ray computed tomography (CT) magnetic resonance imaging (MRI), and ultrasound, which are used to image structures and typically, at low spatiotemporal resolution (millimeters, seconds); and; optical endoscope technologies, which are used to image surfaces at high spatiotemporal resolution (micrometers, milliseconds).
By changing the pulse delays, the computer can scan the beam of ultrasound in a raster pattern across the tissue. Echoes reflected by different density tissue, received by the transducers, build up an image of the underlying structures. Weld examination by phased array. TOP: The phased array probe emits a series of beams to flood the weld with ...
