Esaote was founded in Genoa in 1982 as a division of Biomedical Electronics Ansaldo Ansaldo SpA. In 1984, its activities with those of Elsag SpA converge in Esacontrol. In 1986 STET acquires Tuscan Officine Elettromeccaniche Biomedica - OTE Biomedica Elettronica SpA and in 1988 moved to the Finmeccanica which shall merge it with the biomedical sector Esacontrol, [1] giving rise to Esaote ...
The PA probe consists of many small ultrasonic transducers, each of which can be pulsed independently.By varying the timing, for instance by making the pulse from each transducer progressively delayed going up the line, a pattern of constructive interference is set up that results in radiating a quasi-plane ultrasonic beam at a set angle depending on the progressive time delay.
The transducer may be used in contact with the skin, as in fetal ultrasound imaging, or inserted into a body opening such as the rectum or vagina. Clinicians who perform ultrasound-guided procedures often use a probe positioning system to hold the ultrasonic transducer. [9] Compared to other medical imaging modalities, ultrasound has several ...
The transducer is typically separated from the test object by a couplant [4] such as a gel, oil or water, [1] as in immersion testing. However, when ultrasonic testing is conducted with an Electromagnetic Acoustic Transducer (EMAT) the use of couplant is not required. There are two methods of receiving the ultrasound waveform: reflection and ...
Conventional Converging Ultrasonic Horn, produced by Industrial Sonomechanics, LLC [1] Full-wave Barbell Ultrasonic Horn, produced by Industrial Sonomechanics, LLC [1]. An ultrasonic horn (also known as acoustic horn, sonotrode, acoustic waveguide, ultrasonic probe) is a tapering metal bar commonly used for augmenting the oscillation displacement amplitude provided by an ultrasonic transducer ...
Nanosonics is a ASX-listed company in the healthcare industry which manufactures and distributes ultrasound probe disinfectors and other related technologies. It has offices in Australia, the U.S. and Canada, the United Kingdom and Europe, [2] employing more than 300 people.
In (semi-) automated probe positioning systems, a control system corrects for the movement of the object or disturbances in the environment. These systems can use a tilt, pressure or other sensor carried by the probe to collect positional data. The positioner, such as a robotic arm is coupled to the probe. The positioner can provide roll and ...
The frequency content of the generated ultrasound is partially determined by the frequency content of the laser pulses with shorter pulses giving higher frequencies. For very high frequency generation (up to 100sGHz) femtosecond lasers are used often in a pump-probe configuration with the detection system (see picosecond ultrasonics).
