The A1 device converter has a stable and fixed shape compared to its competitors. The thermal lesion is oval in shape, which leads to better therapeutic results (if the created thermal lesion is vertical and elongated, it can cause burns in the surrounding areas, such as around the eyes).
High frequency transfers more energy and creates a more desirable thermal lesion; therefore, to enhance treatment effectiveness at lower skin depths, a high-frequency converter should be used. Only a limited number of companies worldwide have commercialized this technology. The A1 device is equipped with a 10 MHz converter with a penetration depth of 1.5 millimeters, as well as six other types of converters.
In HIFU devices, ultrasonic waves are emitted for a duration of 10-40 milliseconds, which results in the creation of distinct thermal lesions at the desired depth.
Having these types of cartridges allows for better coupling with the skin in elevated areas of the face, such as the ends of the forehead, without the need to shorten the effective length of the converter.
