Resumo

Sonothrombolysis consists in a new treatment based on ultrasound to help to unblock arteries that may be blocked by a thrombus, helping in infarct treatment as a noninvasive method. Although it is a new method, it has shown great progress thorough recent years. Among the variety of applications of this technology, the Phased Array Ultrasound Technique (PAUT) can achieve a higher pressure with the same power using the focused beam concept. In this paper, this technique is analyzed as a tool for sonothrombolysis treatment and compared to other conventional techniques. The advantages of the phased array ultrasound technique are shown by wave simulation programs. After that, a project for an ultrasound device prototype is introduced. The project implementation and its characteristics are also explored herein. (AU)
