The use of ultrasound technology for medical purposes, although it justifies itself in terms of the effectiveness of the diagnosis of various diseases and disorders, still may not always be the only right decision – for the simple reason that it requires the use of a special marker attached to the patient’s skin. In the case of young children and victims of severe burns, this may not work, and therefore a team of talented medical specialists from the Massachusetts Institute of Technology introduced a new hybrid development that combines both ultrasound technology and laser pulsation technology, without the need for skin markers.
This will greatly facilitate many procedures for the diagnosis of various diseases and, in general, make such diagnostics faster and more efficient. The created system operates as follows: first, one stream of laser pulsations is launched, aimed at the examined site, and then, when these pulsations are reflected from the skin, a second laser stream is used to convert these pulsations into a visual display. The result is a fairly accurate and detailed picture of the site being examined, indicating possible violations.
In particular, the development scientists have already conducted several similar tests on several subjects and found that their technology allows you to easily look at a depth of tissue up to 6 cm, which cannot but impress – and the technique allows you to specify almost any type of tissue in the correct sequence, using 1,550 nanometer laser pulsations, possessing not only small size, but also high accuracy.
It is worth noting that so far the presented technology continues to be developed and tested by scientists, but now there is no doubt that it will soon become truly unique and, possibly, will give a second wind to the hybrid technology of pulsation and ultrasound. Given the current successes and achievements of the team of scientists from MIT, there is less and less doubt in this regard, despite some parallel difficulties in the work.
