HIGH FREQUENCY ULTRASOUND IMAGING BY ROTATIONAL SCANNING OF ANGLED TRANSDUCERS

摘要

Techniques are described, including systems, methods, and mechanisms/apparatus (e.g., probes), for high frequency ultrasonic imaging structure of small vessels and tissues of a surgical site during and after performing a microsurgical procedure such as ophthalmic surgical procedure and endoscopic procedure. A rotational motor and controller control a partial or full rotation of an angled transducer for scanning of tissues or small vessels using high frequency ultrasound over 30 MHz for high spatial resolution. This rotational sector or polar imaging from a rotation of an angled ultrasound transducer can be used with endoscopes or intravascular ultrasound (IVUS) systems. The rotational imaging systems and methods also can be used with the Doppler analyzer as a duplex imaging system to measure blood flow from small vessels.
