Ultrasound Scanner Technology
The ultrasound technology has been constantly improvised. It has undergone lot of upgradation before evolving as the real-time ultrasound scanner of today. Some of the significant developments in Ultrasound scanner technology are listed out in this section. They are: 1) Digital Signal Processing Chain 2) Ultrasound Scanner with a beam former 3) The phase data in returning ultrasound echoes 4) The advent of tissue harmonic imaging 5) Portable Ultrasound Scanner Technology 6) Ultrasound Computed Tomography-High Speed Data Acquisition Digital Signal Processing Chain Previously the beamformer (employing analog delay lines) and the signal processing stages are usually analog in their operation. The digital change-over was based on the very powerful computer platforms that were only available after the mid 1990s.
The invention relates to an active ultrasound scanner, which renders objects in a medium recognizable, which are obscure, not visible through a curtain of smoke or mist, or are, for example, in dirty water (harbor basin, river water). Ultrasound Scanner with a beam former The apparatus for examining an object by means of ultrasound has an emitting transducer and a receiving transducer with a plurality of transducer elements.
Extensive use of refined broad-band wide aperture transducers With wide aperture transducers, transmit and receive apodization also allowed for the electronic reduction of the lateral array elements (sidelobes). Therefore lateral resolution will be best (smallest) if there is a large aperture and short wavelength (higher frequency). The phase data in returning ultrasound echoes The phase data in returning ultrasound echoes, in addition to the amplitude data are processed in what is known as coherent image processing. The technique produced twice the amount of data from which to create ultrasound images of high resolution.
The advent of tissue harmonic imaging In a nutshell, tissue harmonic Imaging made use of lower frequency sound waves to improve penetration, while receiving and processing only the higher frequency echoes produced by the body's inherent harmonic characteristics
Portable Ultrasound Scanner Technology Portable ultrasound scanner is an invaluable aid to medical practitioners, especially in rural areas, in the early diagnosis of the medical-surgical problems of their patients.
Portable Bladder Ultrasound Technology In May 2005, the Continence Care Panel was formed. The Panel discussed technologies used in the management of urinary conditions and recommended some for review by Ontario Health Technology Advisory Committee. These technologies included hydrophilic catheters, bladder ultrasound, and pessaries. This health technology and policy assessment focuses on portable bladder ultrasound.
Ultrasound Computed Tomography-High Speed Data Acquisition This report describes the development of an experimental system for ultrasound computed tomography and its application to breast imaging. Details of the system design and methods of high-speed data acquisition are presented.
For general ultrasound technology B-K medical offers advanced scanner technology and specially designed transducers. This has resulted in scanning systems which are not only well-suited to the needs of the general ultrasound practitioner, but are also easy to operate. You thus avoid the need for time-consuming and expensive training.
Recently, the ultrasound user has been faced with a barrage of information from many manufacturers regarding the basic electronic technologies in ultrasound instruments. The digital- analog comparison has been among the most broadly touted and debated of these technologies.
