The twin-turboprop, high-wing aircraft has a retractable gear and came in two variants: the initial N22, followed by the stretched N24. Supported by the Australian Government, design work began in the mid-1960s, and it made its maiden flight on 23 July 1971. Despite some export sales and commercial operations, sales were not sufficient and ...
Therefore, most conventional ultrasound methods require the use of some type of acoustic coupling medium in order to efficiently transmit the energy from the sensor to the test material. Couplant materials can range from gels or jets of water to direct solder bonds. However, in non-contact ultrasound, ambient air is the only acoustic coupling ...
A curvilinear array ultrasonic transducer for use in medical ultrasonography Inside construction of a Philips C5-2 128 element curved array ultrasound sensor. Ultrasonic transducers and ultrasonic sensors are devices that generate or sense ultrasound energy. They can be divided into three broad categories: transmitters, receivers and transceivers.
An ultrasound research interface (URI) is a software tool loaded onto a diagnostic clinical ultrasound device which provides functionality beyond typical clinical modes of operation. A normal clinical ultrasound user only has access to the ultrasound data in its final processed form, typically a B-Mode image, in DICOM format.
Current iSpec 2200 comprises a suite of data specifications and data modules for the digital representation and exchange of technical data. Objective is to: Minimize cost and effort expended by operators and OEMs; Improve information quality and timeliness; Ensure that manufacturers provide data that meets airline operational needs
In the field of industrial ultrasonic testing, ultrasonic thickness measurement (UTM) is a method of performing non-destructive measurement (gauging) of the local thickness of a solid element (typically made of metal, if using ultrasound testing for industrial purposes) based on the time taken by the ultrasound wave to return to the surface.
Ultrasound energy is transferred based on the frequency and power output of the ultrasonic waves that an ultrasound machine or device creates. Home ultrasound machines and doctor's office machines both operate between 1 and 5 megahertz , however, home machines utilize pulsed ultrasonic waves while professional ultrasound machines in a doctor's ...
Ultrasound duplex scanning can provide additional information that may guide therapeutic decisions. The location and severity of arterial narrowings and occlusions can be identified. The vascular sonographer can map disease in lower-extremity segments with great accuracy, though duplex scanning is more time-consuming than other lower-extremity ...
